BMR Suspension Rear Lowering Springs

2008–2023 Dodge Challenger / Charger V8 Engines

Part #: SP112R

Overview

The BMR Rear 1.25" Drop Lowering Springs are engineered to enhance the handling and appearance of your 2008–2023 Dodge Challenger and Charger equipped with V8 engines, including R/T, SRT, Hellcat, Demon, and Redeye models. Designed specifically for street performance, these springs lower the rear of your vehicle by approximately 1.25 inches, reducing body roll and improving overall ride quality. Over time, factory springs can sag or corrode, diminishing performance and aesthetics. BMR’s high-quality lowering springs restore and elevate your suspension’s capabilities, delivering a more aggressive stance and sharper cornering response without compromising daily drivability.

Construction & Design

BMR Suspension’s lowering springs are crafted from premium chrome silicon high-tensile spring wire, a material known for its excellent strength-to-weight ratio and resistance to fatigue. The springs are cold-wound on CNC coiling machines, ensuring each coil meets exacting dimensional and performance standards. Following coiling, the springs undergo a stress-relief process at 750 degrees Fahrenheit to eliminate internal stresses and improve longevity. A shot-peening treatment further enhances the springs’ durability by inducing beneficial surface compressive stresses. The final red powder coat finish not only protects against rust and corrosion but also adds a clean, aggressive look that complements the aggressive styling of Dodge muscle cars.

Performance & Sound

By lowering the rear suspension approximately 1.25 inches, these springs reduce the vehicle’s center of gravity, which significantly improves handling dynamics. The decreased body roll enhances cornering stability and driver confidence during spirited driving. While these springs are designed primarily for performance and handling improvements, they also contribute to a more aggressive stance that visually communicates your vehicle’s enhanced capabilities. The ride quality remains balanced for street use, maintaining comfort without sacrificing performance.

Installation & Fitment

Installation of the BMR Rear Lowering Springs is straightforward and typically takes between 2 to 3 hours. They are designed as direct replacements for the factory rear springs on 2008–2023 Dodge Challenger and Charger models equipped with V8 engines, requiring no additional modifications. It is important to note that the actual ride height drop may vary depending on your vehicle’s engine and accessory configuration. For example, vehicles equipped with a supercharger and air conditioning may sit slightly lower than those without these components due to additional weight on the springs.

What's Included

• Set of 2 BMR Rear Lowering Springs (SP112R)
