Unleash the full potential of your classic A-body muscle car with the UMI Performance Stage 5 Handling Kit. This comprehensive pro-touring suspension upgrade is engineered to deliver superior cornering, stability, and an exhilarating driving experience, whether on the street or the track.
At the heart of this kit are Viking double-adjustable coilovers, allowing precise tuning of ride height and damping for personalized comfort and aggressive performance. Complementing the coilovers are tubular control arms featuring taller ball joints for optimized camber curves and reduced bump steer, ensuring confident handling through every turn.
The kit includes substantial 1.25″ front and 1.00″ adjustable rear sway bars to dramatically minimize body roll, enhancing responsiveness and control. Precision is further refined with Delrin® and spherical bearing bushings, providing smooth articulation and sharp steering feedback. A chassis stiffener brace is also included to bolster frame rigidity.
Designed for 1960s and 70s Pontiac, Oldsmobile, Chevrolet, Buick, and GMC A-body models, this bolt-on system requires no cutting or welding. It’s the ultimate solution for classic muscle car owners seeking to elevate their vehicle’s handling to modern performance standards.
