UMI Performance 6400-1 - 73-87 GM C10 Lowering Kit (4.5in Front/6in Rear) with UMI shocks
Lowering Kit - 4.5 in Front / 6 in Rear - Coil Springs / Hardware / Spindles - GM Fullsize Truck 1973-87 - Kit
UMI’s 6400-1 kit drops C10s 4.5”/6” for improved stance and handling. Includes drop spindles, springs, Bilstein B6 shocks, and rear flip kit—no notch needed. Fits ’73–80; ’81–87 require 1.25” rotor upgrade.
Designed specifically for the 1973-1980 GM C10 trucks, these spindles fit perfectly with 1-1/4" brake rotors. If you own a 1981-1987 model, you might find that it comes with 1" brake rotors. In such cases, you'll need to upgrade to the 1-1/4" rotors used on the earlier models to ensure compatibility and optimal performance.
- 4.5” front / 6” rear drop for a low, aggressive stance

- Includes 2.5” drop spindles, 2” lowering springs, and rear flip kit
