The Detroit Speed, Inc. Universal length Swivel-Link™ Rear Suspension Kit is a terrific way to upgrade the rear suspension for various trailing arm applications. Detroit Speed's unique rear trailing links incorporate our patented Swivel-Link™ system. These tubular trailing arms eliminate bind allowing the rear suspension to fully articulate without the use of noisy spherical rod ends. ith the Swivel-Links™ pinion angle and/or wheelbase can be adjusted without unbolting the link from the car. The Swivel-Link™ Rear Trailing Links allow for easy pinion angle adjustment for improved traction and lower driveline vibrations. Detroit Speed offers these links in 2 and 4 foot lengths so you can cut them to length to fit various applications.
