AWR believes so strongly in their engine mounts and sway bars that they back them with a limited Lifetime Warranty. What's more, this warranty, excluding bushings, is retroactive to all mounts and sway bars built previously by AWR. Basically, if it breaks or fails, AWR will fix or replace it at their discretion. The warranty is 'limited' in that bushings are considered a normal wear item, so the urethane or rubber bushings are not covered, but if the metal cracks, breaks or otherwise fails, we'll replace or repair it.
