4 Link Kit - Uppers Triangulated Single triangulated suspension kit with angled upper links This kit takes the guesswork out of building a single-triangulated 4-link by triangulating the upper links to eliminate side-to-side axle movement—no panhard bar required. Ideal for rear suspensions where keeping the axle area clean and open is a priority, it works with coilovers, emulsion shocks, or coil springs. If you've got the packaging space for an axle truss or upper link tower, this setup delivers reliable geometry without unnecessary complexity. Includes everything you need to build your 4-link, minus the tubing. Note: All link brackets and the included bolt kit use 9/16" bolts. If you need to run a larger size, you'll need to drill the brackets yourself.
