Key Features

4" Front / 6" Rear Ride Height Drop
Provides an aggressive lowered stance while maintaining suspension travel and ride quality. Actual ride height may vary depending on wheel and tire size.

2" Drop Spindles
Engineered to increase negative camber gain for improved tire contact during cornering. The 2-inch pin drop allows the use of longer shocks, increasing suspension travel and ride comfort.

Ridetech Upper StrongArms
Designed with corrected ball joint angles and increased caster capability to improve high-speed stability and steering feel. Injection-molded Delrin bushings with 13% Teflon reduce suspension deflection and friction.

Ridetech Lower StrongArms
Feature a double-shear lower shock mount for increased strength and durability. The lower ball joint is repositioned to improve caster while keeping the wheel centered in the wheel opening. Includes cross shafts and installation hardware.

HQ Series Adjustable Coilovers
Ridetech HQ coilovers feature an impact-forged aluminum body and monotube shock design for excellent ride quality and handling. Adjustable rebound allows fine tuning of suspension performance, with adjustment knobs accessible under the hood.

Front MuscleBar Sway Bar
Manufactured from massive 1.5" x .250" wall tubing to minimize body roll and improve cornering stability. Includes billet aluminum frame straps and low-friction bushings for smooth suspension operation.

Rear Bolt-On 4-Link Suspension
The Ridetech rear 4-link system increases traction and strength while utilizing R-Joint Technology to provide low-friction movement, lateral stability, full articulation, and quiet operation.

The rear suspension is a 100% bolt-on design requiring minimal cutting and no welding. C-notch brackets tie directly into the upper crossmember while link bar mounts use factory bolt holes and axle mounting points.
