Product Details
This front coilover kit from UMI Performance uses Viking Crusader AT valved shocks paired with 850 lb/in Hyperco springs, a setup designed for serious performance on the street, track, or autocross course. The Viking Crusader shocks offer double adjustability, allowing you to fine-tune both compression and rebound damping. This means you can dial in a comfortable ride for daily driving or stiffen it up to minimize body roll and pitch during aggressive maneuvers, keeping the car remarkably flat through transitions. The high rebound force is particularly effective at controlling body movement, while the wide range of compression adjustment lets you tailor the feel from a relaxed cruise to race-ready stiffness.
Designed as a direct bolt-in for many GM G-Body and S10/S15 vehicles, this kit integrates with UMI's 3057 lower A-arms. Installation involves bolting into the stock upper mount location, though you will need to trim the spring location fingers on the factory mount. The kit includes two Viking Crusader shocks with AT pro-touring valving, two Hyperco springs, and a thrust bearing kit to make ride height adjustments smooth and easy. This setup is built to work with UMI's specific A-arm for optimal geometry and performance.
This kit is a solid choice for owners looking to significantly upgrade their vehicle's suspension. It's engineered to work with a range of popular vehicles including the 1978-1988 Chevrolet Monte Carlo, 1982-2003 Chevrolet S10, and 1978-1987 Buick Regal. By providing adjustable damping and a well-matched spring rate, it offers a noticeable improvement in handling and control without sacrificing streetability.
