Return PolicyProduct Overview:
QA1's Heavy Duty Pro Rear Drag 4-link system streamlines the fabrication process, delivering professional-grade results and performance in a convenient and easy-to-order kit all from one source. This 4-link system is designed for the hardcore, discerning, do-it-yourself racer looking for a no-compromise solution to take their vehicle to the next level in performance and adjustability. High quality, MIG-Weldable components ensure a safe and properly engineered design that can be easily adapted into many drag racing setups. Find convenience, safety, and performance all from QA1 with the HD Pro Rear Drag 4-Link.
Performance:
This drag race-style 4-link design is known for its performance and adjustability, and features a wide range of instant center tuning and on-car adjustability. The components are adaptable and can be cut to length to work in any setup with 40 inch or narrower frame-rails. QA1's 7 inch travel, track-proven shocks round out the kit and offer adjustability for changing track conditions and plenty of travel and ride height tuning.
Heavy Duty Design:
This heavy-duty design can handle the demands of high-performance racing. With ¼ inch-thick plates, 1-1/4 inch trailing arm tubes, Grade 8 hardware, and QA1 chromoly rod ends, these kits are built to put down serious power.
Adaptability:
This kit contains all the components and hardware needed for assembly and mounting of the trailing arms, shocks, springs, and uses a diagonal link for lateral locating of the axle. However, all components can be purchased individually as well if different shock options or configurations are required for a particular build. Look to QA1 for components that will help with any drag race suspension setup.
Look to the provided dimensional diagrams and renderings to help with your custom install.
