QA1 HD Pro Rear Weld-In Coilover Kit 300lb/in. S-Adj. 3.00in

QA1 is well-known for its suspension components, and their Heavy Duty Pro Rear Systems are a prime example of that expertise. If you're looking to upgrade your car or truck's rear suspension with coilovers, this kit is designed to make that happen. It's built for vehicles with a rear axle weight between 1700 and 2600 pounds, offering a robust solution for both street driving and track use.

This kit simplifies the conversion process with a weld-in design that includes all the necessary brackets, tabs, and hardware. You get double shear bracketry for added strength and springs with a 300 lb/in rate, which is a solid choice for many applications. The single-adjustable QA1 Proma Star shocks let you easily dial in your preferred damping – a quick turn of a knob can change the feel from comfortable cruising to a more aggressive setting for spirited driving. You'll also have a total of 9 inches of ride height adjustability between the axle-mounted brackets and the coilover shock itself, giving you precise control over your vehicle's stance. The upper shock mount tubing is 1-5/8 inch diameter, .095 wall, and 40 inches long, designed to fit 3.00 inch axle tubes.

Installation is straightforward for those comfortable with welding. Everything you need to get the coilovers mounted is included, so you won't need to make extra trips for parts. QA1 backs this kit with a best-in-class lifetime warranty when registered, and it's proudly made in the USA. You will need a QA1 spanner wrench (T114W or T115W) to make adjustments.
