QA1 DM501-12130 Pro-Rear MOD Series Double-Adjustable Coilover Conversion Kit 130 lb/in 3.00in Axle

The QA1 DM501-12130 is a Pro-Rear MOD Series coilover conversion kit designed for custom weld-in rear suspension builds on non-leaf spring vehicles. Engineered for drag racing, street performance, and street rod applications, this complete kit delivers precise, tunable damping with a 130 lb/in spring rate sized for 3.00-inch diameter axle tubes.

The MOD Series shocks at the heart of this system feature modular valve packs that allow valving changes without removing the shocks from the vehicle — making on-car tuning faster and easier. Independent compression and rebound adjustability gives you full control over your suspension's behavior in any driving condition. Each shock is 100% dyno tested and serialized for guaranteed performance consistency.

• MOD Series Double-Adjustable Shocks — independent compression and rebound tuning for maximum setup flexibility
• 130 lb/in Spring Rate — 12-inch linear coilover springs included, silver powdercoated finish
• 3.00-Inch Axle Tube Compatibility — designed for vehicles with 3.00" diameter rear axle tubes

• 5/8" Centerless Ground, Hard Chrome Plated Solid Piston Rod — for durability and consistent performance
