QA1 Pro Parallel 4-Link System- (Rear)

If you're building a custom hot rod or truck and need to set up a solid rear suspension, this QA1 Pro Parallel 4-Link System is a great way to get there. It simplifies the process of adding a four-link setup, especially for vehicles that don't have a lot of aftermarket support. This kit gives you the foundation to achieve a dialed-in stance and improved ride quality.

QA1 designed this kit for DIY builders, so it includes MIG-weldable components that are straightforward to adapt. You'll get everything needed to mount the trailing arms, shock mounts, and the panhard bar. The trailing arms themselves adjust from 24-5/8" to 25-½", and the panhard bar can be up to 37" long, allowing you to fine-tune your axle position and pinion angle. The adjustable coilover mounts mean you can set your ride height exactly where you want it. Just remember you'll need to add your own coilovers to complete the setup.

This system is built to be adaptable, with components that can be cut to length and welded to fit your specific chassis. The parallel four-link design is known for packaging well, even in tight spaces. You'll find the trailing arms are powder coated for looks and durability, and they come with forged bushings for a smoother ride. This kit is made in the USA and includes all the necessary hardware for installation, including brackets for a 3-inch axle tube and a 40-inch trailing arm crossmember.
