What to Know Before You Buy
2011–2013 vs. 2014–2018 Fitment
The 4th-gen Ram 2500 had a mid-cycle update for 2014. Most kits on this list fit 2011–2018; some (Eibach, Fabtech 5in Basic, Fabtech Radius Arm) are validated for 2014–2018 only. If you have a 2011–2013 model, confirm fitment with the manufacturer before ordering. Superlift, Fabtech 2.5", and ICON 4.5" explicitly fit the full 2011–2018 range.
Gas vs. Diesel Fitment
The 2011–2018 Ram 2500 is offered with the 6.4L Hemi gas or 6.7L Cummins diesel. Most lift kits fit both. The Eibach Pro-Truck is designed specifically for the 6.7L Cummins 4WD. Gas 2500 owners should choose Superlift, Fabtech, or ICON. Always verify engine fitment before ordering.
Tire Clearance by Lift Height
A 2" lift comfortably clears 33" tires on the 4th-gen Ram 2500. A 2.5" lift handles 33–35" tires. A 4.5–5" lift fits 35" tires cleanly and opens the door to 37" with proper wheel backspacing. The 4th-gen Ram 2500 has solid front axle geometry; at 5"+ lifts, radius arm upgrades improve caster and ride quality.
Radius Arm vs. Spacer Design
The 4th-gen Ram 2500 uses a radius arm front suspension with coil springs. Spacer kits (Superlift, Fabtech 2.5", ICON) retain the factory radius arms. Radius arm replacement kits (Fabtech 5") improve caster and geometry for 5"+ lifts. At 2–2.5", spacers are sufficient; at 5"+ consider the full radius arm upgrade for best ride and handling.
Superlift 2in Suspension Lift Kit w/ Shocks
The Superlift 2" Suspension Lift Kit is the most affordable complete lift for 2011–2018 Ram 2500 and Ram 3500. Unlike spacer-only kits, this system includes front and rear Superlift shocks valved for the lifted application, so you get a true suspension upgrade at a budget price. The 2" lift comfortably clears 33" tires and maintains factory driveline geometry, so you typically won’t need adjustable control arms or driveline corrections. Superlift has been building truck lifts since 1975, and their Ram HD kits are proven for daily driving and light off-road use.
This kit fits Ram 2500 and 3500 from 2011 through 2018. The 2" lift is the sweet spot for 4th-gen HD Ram owners who want a modest stance improvement and tire clearance without the complexity of a 4.5" or 5" system. At $480, it’s the lowest-priced complete lift on this list for 2500/3500 owners.
Pros
- Lowest price on this list ($480)
- Includes front and rear shocks
- Fits 2011–2018 Ram 2500/3500
- 2" lift preserves driveline geometry
- Superlift’s 50+ years of truck lift expertise
Cons
- 2" lift limits tire size to 33"
- Superlift shocks are functional but not premium-tier
- Moderate lift vs. 4.5" or 5" options
Fabtech 2.5in Coil Spacer Kit w/ Performance Shocks
The Fabtech 2.5" Coil Spacer Kit with Performance Shocks is the best value for 2011–2018 Ram 2500 owners. It uses angled coil spacers that preserve the factory coil spring geometry, delivering a clean 2.5-inch lift front and rear. The included longer front shocks and extended bump stops ensure full suspension travel and prevent coil bind. Fabtech has been building truck lifts for over 25 years, and this kit is engineered specifically for the 4th-gen Ram HD platform.
This kit fits Ram 2500 from 2011 through 2018. The 2.5" lift levels the truck and clears up to 35" tires with minimal modifications. At $488, it’s only slightly more than the Superlift but adds half an inch of lift and Fabtech’s proven spacer design. If you want a modest stance improvement with room for 33–35" tires, the Fabtech 2.5" with Performance Shocks is the value pick.
Pros
- Best value for 2.5" lift ($488)
- Fits full 2011–2018 Ram 2500 range
- 2.5" lift clears 33–35" tires
- Preserves factory ride characteristics
- Includes longer shocks and bump stops
Cons
- Spacer design, not a true spring replacement
- Does not improve suspension travel
- Performance shocks are functional but not premium-tier
Fabtech 2.5in Coil Spacer Kit w/ Stealth Shocks
The Fabtech 2.5" Coil Spacer Kit with Stealth Shocks steps up from the Performance shock package with Fabtech’s Stealth monotube shocks. Monotube designs dissipate heat more efficiently than twin-tube shocks, providing more consistent damping during repeated off-road use. The same angled coil spacers preserve factory geometry, so you get the same 2.5" lift with better ride quality and control. This is the sweet spot for Ram 2500 owners who want a mild lift with noticeably improved damping.
Fitment matches the Performance version: Ram 2500 2011–2018. At $660, it’s roughly $170 more than the base kit but delivers a meaningful upgrade in shock performance. If you plan to use your Ram for towing, light off-roading, or daily driving on rough roads, the Stealth package is the best for ride quality at the 2.5" lift height.
Pros
- Stealth monotube shocks for better damping
- Fits 2011–2018 Ram 2500
- Preserves factory ride and geometry
- 2.5" lift clears 33–35" tires
Cons
- Still a spacer design
- Moderate lift limits tire size vs. 5" kits
Eibach Pro-Truck Lift Kit (Springs & Shocks)
The Eibach Pro-Truck Lift Kit is our Best Overall pick for 2014–2018 Ram 2500 owners with the 6.7L Cummins diesel. Unlike spacer kits, Eibach replaces the factory front springs with purpose-built lift springs and pairs them with sport-tuned shocks. The result is +2.75" front and up to 1.5" rear lift with improved ride quality and suspension travel. Eibach’s off-road race spring technology ensures durability, and the million-mile warranty backs it. Made in the USA.
Important: This kit fits 6.7L Cummins 4WD only and is validated for 2014–2018. Gas 6.4L Hemi 2500 owners need Fabtech or ICON. The 2.75" front lift clears 33–35" tires. If you have a Cummins-powered Ram 2500 and want the best combination of ride quality, durability, and tire clearance, the Eibach Pro-Truck is the pick. It’s currently on sale at $930, down from $1,034.
Pros
- True spring replacement, not spacers
- 2.75" front / up to 1.5" rear lift
- Million-mile warranty, Made in USA
- Best ride quality in this price range
- Race-derived spring technology
- Currently on sale — $930 (down from $1,034)
Cons
- 6.7L Cummins only — gas 2500 excluded
- 2014–2018 fitment (2011–2013 confirm with Eibach)
- Moderate lift vs. 5" options
ICON 4.5in Box Kit
The ICON 4.5" Box Kit delivers a substantial lift for 2011–2018 Ram 2500 owners who want to clear 35" tires without stepping up to a 5" system. ICON Vehicle Dynamics is based in California with roots in Baja 1000 and King of the Hammers competition. This complete system includes dual-rate front springs, rear components, and ICON shocks valved for the lifted application. The 4.5" lift is the sweet spot between moderate 2.5" kits and aggressive 5" systems.
Fitment covers the full 2011–2018 Ram 2500 range. At $1,180, it’s the most affordable 4.5"+ lift on this list. The dual-rate springs provide a softer initial rate for comfort and a firmer secondary rate for load support and bottom-out protection. If you want to run 35" tires and need more lift than the 2.5" options provide, the ICON 4.5" Box Kit is the mid-range pick.
Pros
- 4.5" lift clears 35" tires
- Fits full 2011–2018 Ram 2500 range
- Dual-rate springs for comfort and control
- Complete system with shocks
- Race-proven ICON engineering

- Retains factory radius arms
Fabtech 5in Basic Kit w/ Performance Shocks
The Fabtech 5" Basic Kit delivers the most aggressive lift on this list for the 2014–2018 Ram 2500. It retains the factory coil springs and uses heavy-duty steel components to achieve a full 5 inches of lift front and rear. The included Performance shocks are valved for the lifted application, and the system maintains factory load capacity. This is the kit for Ram 2500 owners who want maximum stance and 35–37" tire clearance.
Fitment is 2014–2018 Ram 2500. At 5" of lift, you’ll want to budget for an alignment and possibly driveline corrections if you experience vibrations. Fabtech also offers a Radius Arm Kit ($2,552) that replaces the factory radius arms for improved geometry at this lift height. For Ram HD owners who want a bold lift at a reasonable price, the 5" Basic Kit is the aggressive pick.
Pros
- 5" lift — largest on this list
- Clears 35" tires easily, 37" with setup
- Maintains factory load capacity
- Complete system with shocks
Cons
- 2014–2018 fitment only
- 5" lift may require driveline corrections
- Retains factory radius arms — geometry at limit
- Stiffer ride than 2.5" kits
Fabtech Radius Arm Kit w/ Performance Shocks
The Fabtech Radius Arm Kit replaces the factory radius arms with Fabtech’s tubular radius arms and introduces a straight coil spring design that addresses the harsh ride common in stock Ram HD front suspensions. The factory bowed coils are replaced with vertical coils on patented angled spring seats, delivering a smoother, more controlled ride. The 5" lift clears 35" tires easily and accommodates 37" with proper setup. This is the kit for Ram 2500 owners who want maximum capability with improved ride quality.
Fitment is 2014–2018 Ram 2500. The radius arm upgrade improves caster angle for better steering and tire wear with oversized tires. Fabtech also offers this kit with Dirt Logic 2.25 DLSS shocks ($3,377) for upgraded damping.

Common Questions
Frequently Asked Questions
Do lift kits for 2011–2013 Ram 2500 fit 2014–2018 models?
Most kits that fit 2011–2018 will fit both. The 4th-gen Ram 2500 had a mid-cycle update for 2014; some manufacturers validate 2014–2018 only (Eibach, Fabtech 5in Basic, Fabtech Radius Arm). Superlift, Fabtech 2.5", and ICON 4.5" explicitly fit the full 2011–2018 range. If you have a 2011–2013 model, confirm fitment before ordering.
Do I need new shocks when installing lift springs or spacers?
All seven kits on this list include shocks. If you’re installing a spacer-only kit from another brand, you should pair it with shocks designed for your new lift height. Factory shocks are valved and travel-limited for stock height — they’ll bottom out or top out at 2"+ lifts. Superlift, Fabtech, Eibach, and ICON all include matched shocks in their kits.
I have a 6.4L Hemi Ram 2500. Does the Eibach kit fit?
No. The Eibach Pro-Truck Lift Kit is designed specifically for the 6.7L Cummins 4WD. Gas 6.4L Hemi 2500 owners should choose Superlift, Fabtech, or ICON. All other kits on this list fit both gas and diesel configurations.
Will a lift kit cause driveshaft vibrations?
Lifts of 2" or less rarely cause driveline vibrations on the 4th-gen Ram 2500. At 2.5", most trucks are fine. At 4.5–5", some may develop a slight vibration at highway speeds. Driveshaft angle correction (adjustable control arms or carrier bearing spacer) may be needed. Fabtech’s radius arm kit improves caster and geometry to minimize these issues. Budget for an alignment after any lift installation.
What is the difference between a spacer lift and a spring lift?
Spacer lifts (Superlift, Fabtech 2.5", ICON) place a spacer on top of or within the factory coil spring, pushing the vehicle up without changing the spring. They’re simpler and often cheaper, but don’t improve suspension travel. Spring lifts (Eibach, Fabtech radius arm) replace the factory springs with purpose-built lift springs. They can improve ride quality and load capacity. The Eibach Pro-Truck is the only true spring replacement in this guide for the 4th-gen 2500.
How much lift do I need to clear 35-inch tires?
A 2.5" lift will physically fit 35" tires on most 2011–2018 Ram 2500s, but you may need minor trimming at full lock. A 4.5" lift fits 35" tires cleanly, and a 5" lift accommodates 37" with proper wheel backspacing. The 4th-gen Ram 2500 has solid front axle geometry; wheel offset and tire width are the main constraints. Always confirm fitment for your specific wheel and tire combination.
