4 Link Kit Lowers Triangulated

4 Link Kit - Lowers Triangulated

Single triangulated suspension kit with angled lower links

Building a single triangulated 4-link doesn’t have to be complicated. This kit is set up with triangulated lower links and straight uppers—perfect for low-slung crawlers, buggies, and dedicated trail rigs where packaging constraints make upper triangulation tricky. Compatible with coilovers, emulsion shocks, or coil springs, it’s strong, complete, and designed to take the hits without letting your geometry slip. Great for rear suspensions where you want stability, articulation, and a lower center of gravity without over-complicating your setup.

Note: All link brackets come with 9/16" holes. If you select a larger bolt size, you will need to drill out the bracket holes to match.

Available Kit Options

Misalignment Bolt Size:
3/4"
5/8"
9/16"

Link Tower Option:
10 Degree – Best for angled mounting, helps reduce joint bind at extreme articulation. Use when your link geometry comes up at an angle to the axle.
0 Degree – Best when your link is nearly flat or you’re tight on vertical space.

Upper Frame Link Bracket:
Adjustable Link (10 Degree) – Gives multiple mounting options, ideal for dialing in anti-squat and link separation.
3 Legged Link (0 or 10 Degree) – Strong and compact. Great for tight installs or rear upper link mounting to a crossmember or truss.

Rod End Maintenance Tip

Only use Tri-Flow to service rod ends. Using WD-40, PB Blaster, or similar products will cause internal damage and void the warranty.
