What to Know Before You Buy
Your Trim Changes the Drop
The same spring kit will drop a V6 Challenger differently than an R/T or Hellcat. Heavier engines compress springs more. The Eibach E10-27-004-01-22, for example, drops a Scat Pack -0.8" front but a Hellcat Widebody -1.2" front. We break down every trim's expected drop in each product section below.
SRT, Scat Pack & Hellcat Fitment
Performance trims use Bilstein shocks with electronic adaptive damping (EDC). Most standard lowering kits do NOT fit these models. Only the Eibach E10-27-004-01-22 is specifically designed and validated for Scat Pack, SRT 392, Hellcat, and Widebody. Other kits may physically bolt in but aren't tuned for the electronic dampers.
Alignment & Camber Correction
Drops under 1.25" usually stay within factory alignment specs. Anything above 1.25" will likely need aftermarket adjustable upper control arms or camber bolts ($300–$600 extra). Always budget for a professional alignment after installation.
Factory Shocks Still Matter
All kits on this page work with factory shocks. However, if your shocks have 60,000+ miles, they may be worn. Installing new springs on tired dampers results in a bouncy, poorly controlled ride. Consider upgrading to Bilstein B6 dampers ($100–$150 each) if your shocks are worn.
Eibach Pro-Kit Lowering Springs
The Eibach Pro-Kit is the most recommended lowering spring for the Challenger across every major forum — ChallengerTalk, LX Forums, and Reddit. Eibach is the only brand that offers trim-specific kits for this platform, meaning the spring rates are precisely tuned for the weight and suspension geometry of your exact sub-model. They deliver a noticeable drop with near-stock ride quality, and the progressive spring rate keeps daily driving comfortable while improving handling in corners.
For 2015-2023 Challengers, Eibach offers two main kits: one for V6 and R/T models, and another specifically engineered for Scat Pack, SRT 392, Hellcat, and Widebody models. The SRT/Hellcat kit (E10-27-004-01-22) is the only lowering spring on the market validated for Widebody variants and designed to work with the factory Bilstein electronic adaptive damping system.
Drop by Trim — Eibach E10-27-004-01-22 (SRT / Scat Pack / Hellcat)
| Sub-Model | Front Drop | Rear Drop |
|---|---|---|
| Scat Pack | -0.8" | -1.3" |
| SRT 392 | -0.6" | -1.1" |
| SRT Hellcat | -0.9" | -0.9" |
| SRT Hellcat Redeye | -1.1" | -1.0" |
| R/T Scat Pack Widebody | -1.1" | -1.5" |
| SRT Hellcat Widebody | -1.2" | -1.7" |
| SRT Hellcat Redeye Widebody | -1.0" | -0.9" |
Pros
- Only brand with validated Widebody fitment
- Works with factory electronic adaptive damping
- Trim-specific spring rates for precise drop
- Near-stock ride comfort (progressive rate)
- Million-mile limited lifetime warranty
- Made in Germany
- Camber correction usually not needed (under 1.25" drop on most trims)
Cons
- Conservative drop — may not satisfy aggressive stance seekers
- Multiple SKUs can be confusing (make sure you pick the right one for your trim)
- Spring rates not publicly published
H&R Sport Lowering Springs
H&R is the second most popular lowering spring brand in the Challenger community, and for good reason. Their Sport Springs deliver a noticeably more aggressive drop than Eibach's Pro-Kit — approximately 1.7" in the front and 1.4" in the rear — which dramatically closes the wheel gap and gives the Challenger a much more planted, aggressive look. They're made in Germany with a lifetime limited warranty, and the progressive spring rate keeps the ride livable for daily driving despite the significant drop.
H&R offers two kits: the 50880 for V6 models, and the 50888-1 for R/T, SRT8, SRT 392, and Hellcat models. One important note: H&R has not officially validated fitment on Widebody variants. The wider 305-series tires and altered suspension geometry increase rubbing risk. If you own a Widebody, contact H&R directly or consider the Eibach kit instead.
Pros
- More aggressive drop than Eibach Pro-Kit
- Separate V6 and Hemi-specific kits
- Lifetime limited warranty
- Made in Germany, proven quality
- Strong community presence (2nd most popular)
- Covers R/T through Hellcat (narrowbody)
Cons
- Not validated for Widebody models
- At -1.7" front drop, camber correction will likely be needed
- Ride is noticeably firmer than stock (stiffer than Eibach Pro-Kit)
- May require upgraded shocks for optimal ride at this drop height
BMR Suspension Lowering Springs
BMR is the only brand in this comparison that sells front and rear springs individually — making them ideal for owners who just want to fix the Challenger's nose-high "stink bug" look without touching the rear. At $140 for front springs only, it's the cheapest way to improve your Challenger's stance. The full front-and-rear set (SP110R) is $300, making it one of the best values on this list.
Every BMR spring is made in the USA, individually tested, and compressed solid twice before shipping to prevent settling. They publish their spring rates (unlike most competitors) and offer a lifetime sag warranty — if the springs sag, they replace them free. The conservative 1.25" drop means you almost certainly won't need camber correction hardware.
Available Configurations
| SKU | Configuration | Drop | Price |
|---|---|---|---|
| SP111R | Front Only (pair) | -1.25" front | $140 |
| SP112R | Rear Only (pair) | -1.25" rear | $180 |
| SP110R | Full Set (F&R) | -1.25" F&R | $300 |
Pros
- Buy front-only to level the stance ($140)
- Published spring rates (transparent engineering)
- Made in USA, individually tested
- Lifetime sag warranty
- Conservative drop — no camber correction needed
- Works great with factory Scat Pack Bilstein shocks
Cons
- Only -1.25" drop — not enough for aggressive stance builds
- Not marketed for V6 models (designed for heavier V8 weight)
- Less community presence than Eibach or H&R
D2 Racing Pro Series Lowering Springs
At $200, the D2 Racing Pro Series is the cheapest lowering spring option available for the Challenger — and also the most aggressive, with a full 2.2" drop front and rear. If maximum slam on a budget is your goal, this is the kit. But there's a catch: at -2.2", you'll almost certainly need aftermarket adjustable upper control arms for camber correction ($300–$600), will likely scrape on driveways and speed bumps, and the true "all-in" cost approaches $500–$800.
D2 Racing springs are excluded from fitting SRT, Scat Pack, Hellcat, and AWD models. They only work on V6 and R/T trims. Forum reports from long-term owners note that D2 springs can sag over time (5–7 years), gradually settling lower than the advertised drop. The 1-year warranty is the shortest of any product in this guide.
Pros
- Lowest price at $200
- Most aggressive drop (-2.2" F&R)
- Eliminates nearly all wheel gap for maximum stance
Cons
- Excludes SRT, Scat Pack, Hellcat, AWD
- Camber correction almost certainly required (budget extra $300–$600)
- Reports of sagging after 5–7 years
- Only 1-year warranty
- Will scrape on driveways, speed bumps, steep inclines
- Significantly stiffer ride quality
Hurst Stage 1 Performance Spring Kit
The Hurst Stage 1 is the handling-focused choice. Unlike every other spring on this list, Hurst uses a linear spring rate (260–312 lb/in front) rather than progressive. Linear springs provide a consistent, predictable response throughout the entire suspension travel — better for spirited driving and track days, but firmer for daily commuting. This is the spring for the owner who prioritizes cornering grip and turn-in response over ride comfort.
Backed by Holley Performance Products, Hurst is a legacy American muscle car brand founded in 1958. The springs feature a signature gold powder coat for corrosion resistance and distinctive appearance. The drop is trim-dependent: approximately 1.0" on heavier SRT8 models and 1.75" on lighter R/T, SXT, and GT models. With a 4.8/5 star average from 25+ reviews and a lifetime warranty, it's a proven kit — but at $584, you're approaching entry-level coilover territory.
Pros
- Linear rate for predictable, performance handling
- Published spring rates (260–312 lb/in front)
- Lifetime limited warranty (Holley-backed)
- 4.8/5 star average from 25+ owner reviews
- Trim-dependent drop (smart engineering)
- Fits SXT through SRT8 (widest trim coverage)
- Signature gold powder coat finish
Cons
- Most expensive non-adjustable spring at $584
- Linear rate = noticeably firmer daily ride than progressive springs
- At this price, entry-level coilovers become a consideration
- 1.75" drop on R/T may still need camber correction
Function & Form Adjustable Spring Sleeve Kit
The Function & Form is a unique product in this lineup — it's not a traditional lowering spring, and it's not a full coilover. It's an adjustable sleeve system that wraps around your factory shocks, replacing the spring with a height-adjustable unit. You keep your OEM Bilstein electronic dampers (all drive modes still work), but gain the ability to dial in your exact ride height from -1.0" to -2.0". Think of it as a middle ground between springs and coilovers.
Important limitation: this kit is designed for SRT models with Adaptive Damping Suspension (ADS) only. It does not fit base R/T, SXT, or GT models. The trade-off for adjustability at this price point is a shorter 1-year warranty and budget-tier materials compared to the premium ST/KW option below. Function & Form has its roots in the Honda/import community, and Challenger-specific reviews are limited.
Pros
- Adjustable height (-1.0" to -2.0")
- Preserves factory electronic damping (all modes work)
- Cheaper than coilovers or ST Suspensions
- Mild 10–15% spring rate increase keeps ride comfortable
Cons
- Only fits SRT models with ADS (not R/T, SXT, GT)
- Only 1-year warranty
- No damping adjustment (relies entirely on OEM shocks)
- Very limited Challenger community reviews
- Threaded sleeves require periodic maintenance to prevent seizing
- Spring rates not published
ST Suspensions Adjustable Lowering Springs
ST Suspensions is a sub-brand of KW Automotive — the premier German suspension manufacturer. These adjustable springs use KW's engineering, R&D, and vehicle-specific spring rate tuning, but at a lower price point than KW's own H.A.S. kits. The springs are made from chrome-silicon steel, TUV-certified for road safety, and include everything needed for installation: threaded height adjusters, bump stops, and dust protection.
Two variants are available: the 27327018 for vehicles with Electronic Damper Control (EDC), and the 27327019 for vehicles without. The EDC version maxes out at -0.8", while the non-EDC version allows up to -1.0". This conservative range is deliberate — KW engineered these to stay within the safe operating envelope of the factory dampers. Ride quality reports from Challenger forums are excellent, with owners describing the ride as "similar to stock but corners much better."
Which Variant Do You Need?
| Part Number | For Vehicles | Max Front Drop | Max Rear Drop |
|---|---|---|---|
| 27327018 | WITH Electronic Damper Control (Bilstein) | -0.8" | -0.8" |
| 27327019 | WITHOUT Electronic Damper Control (Monroe) | -1.0" | -1.0" |
Pros
- KW German engineering and R&D
- TUV-certified for road safety
- Vehicle-specific spring rates matched to OEM dampers
- Adjustable height within a safe, tested range
- Complete kit (springs, adjusters, bump stops, dust boots)
- 5-year warranty
- Chrome-silicon steel construction
- Excellent ride quality feedback from Challenger owners
Cons
- Most expensive option at $939
- Very conservative drop (max -0.8" to -1.0")
- At this price, full coilovers with damping adjustment become viable
- Not officially validated for 6.2L / 6.4L spring rates
- Height changes require jacking the car and realignment

Common Questions
Frequently Asked Questions
Do I need new shocks when installing lowering springs?
Not necessarily. All kits on this page are designed to work with your factory shocks. However, if your shocks have 60,000+ miles, they're likely worn. Installing fresh springs on tired dampers creates a bouncy, poorly controlled ride. Upgrading to Bilstein B6 performance shocks ($100–$150 each) is recommended if your dampers are worn.
Will lowering springs void my factory warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty just because you installed aftermarket parts. However, if a warranty claim is directly related to the modification (e.g., premature strut wear caused by lowering), the dealer can deny that specific claim. Lowering springs typically don't trigger warranty issues unless they cause a related failure.
Do lowering springs affect ride quality?
Yes, but the degree varies dramatically by product. Conservative drops (0.5–1.25") with progressive-rate springs (like Eibach Pro-Kit or BMR) maintain near-stock ride comfort. Aggressive drops (1.7–2.2") with stiffer spring rates will be noticeably firmer, especially over bumps and rough roads. Linear-rate springs (Hurst) feel firmer across the board but provide more predictable handling.
What's the difference between progressive and linear spring rates?
Progressive springs have a variable rate — soft initially for comfort over small bumps, then stiffening progressively as the spring compresses further. This gives a comfortable daily ride with good control under hard cornering. Most springs on this page are progressive. Linear springs (like Hurst) have a constant rate throughout the entire range of travel. They feel firmer overall but deliver more consistent, predictable handling. Linear is preferred for track-oriented setups.
Should I get lowering springs or coilovers?
Lowering springs are best if you want a set drop at the lowest cost ($200–$600 for springs vs. $1,200+ for quality coilovers). If you want adjustable ride height AND adjustable damping, coilovers are the better choice. The labor cost is roughly the same for both. Check our Suspension Buyers Guide for a full coilover comparison.
I have a Widebody Challenger. What are my options?
Your only validated lowering spring option is the Eibach Pro-Kit E10-27-004-01-22. It's the only kit specifically tested and approved for Widebody suspension geometry and wider 305-series tires. Other brands may physically bolt in, but risk rubbing and fitment issues. For adjustable lowering on a Widebody, consider a full coilover system instead.
