QA1 DM501-12110 Pro-Rear MOD Series Double-Adjustable Weld-In Coilover Kit 110 lb/in 3.00in Axle

The QA1 DM501-12110 is a Pro-Rear MOD Series custom-mount weld-in coilover conversion kit designed for performance-minded builders working with 3.00-inch diameter axle tubes. This complete kit enables you to fabricate your own rear coilover suspension system in virtually any non-leaf spring vehicle, making it a popular choice for drag racing, street performance, and street rod builds.

At the heart of this system are two MOD Series double-adjustable coilover shocks featuring independent compression and rebound adjustment. Each click is precisely calibrated with evenly spaced valving changes throughout the adjustment range, eliminating harsh transitions between settings for smooth, predictable tuning.
