Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you're running a non-standard setup, call us before ordering and we'll confirm compatibility.
Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.
Yes, if you've done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you'd rather have it done.
Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.
Teraflex's lifetime warranty voids if you miss a maintenance interval. MetalCloak's actual parts warranty is 12 months — their "lifetime" language refers to their service program. No conditions here.
