1994-2009 Cummins Adjustable Control Arm Kit (8531-02)

Fits

Restore proper geometry and unlock the full potential of your Ram’s suspension with the Synergy Adjustable Control Arm Kit. When leveling or lifting your Cummins, maintaining correct caster and pinion angles is critical for predictable handling and driveline longevity. This kit replaces weak factory stamped arms with heavy-duty DOM tubing, engineered to correct suspension geometry on trucks with 0" to 3.5" of lift. Featuring maintenance-free Dual Durometer Bushings, this kit improves ride quality while providing the strength needed for heavy towing and off-road abuse.

• Fully adjustable on the vehicle using the Synergy pinch bolt and adjuster sleeve assembly.
• Maintenance-free Teflon® bearing surface in the bushings ensures long-term flex and performance.

Stepped Cam Bolt Eliminators

• Eliminates weak factory cam bolts that are prone to slipping and causing alignment creep.
• Moves all adjustability to the control arms, providing a more secure and precise alignment.
• Specifically designed to work with Synergy Dual Durometer Bushings for a perfect fit.

Synergy Adjustable Front Track Bar (8550-11): The perfect companion to this kit; allows you to fully recenter the front axle and achieve the best alignment possible on lifted Rams.

Synergy Copper Infused Anti-Seize (4118): Highly recommended for the adjuster sleeves to ensure they remain easy to turn for future alignments.
