Elevate your GM A-Body’s performance with the UMI Stage 3.5 Handling Kit. Engineered to deliver razor-sharp handling, this kit replaces your stock suspension with high-performance components designed for aggressive driving.

The foundation of this kit lies in UMI’s ultra-premium lowering springs and rebound-adjustable monotube shocks. The springs offer precisely tuned rates to eliminate float and keep you planted, while the shocks allow fine-tuning of damping for any driving scenario. UMI’s tubular upper and lower control arms, featuring Delrin bushings and caster-corrected geometry, ensure precise steering response and improved stability.

Out back, upgraded trailing arms with Roto-Joints and polyurethane bushings provide smooth articulation and a refined ride. Adjustable upper trailing arms allow for pinion angle correction, and the chassis-mounted Pro-Touring rear sway bar enhances cornering performance without binding. Heavy-duty frame braces and dedicated hardware complete the package.

Designed, manufactured, and tested in the USA, the UMI Stage 3.5 kit combines cutting-edge technology with robust construction. Experience superior handling, improved responsiveness, and a more connected driving feel, whether on the street, track, or autocross course.
