2011-2014 Duramax Extended Travel Front CV Axle Assembly (DMAX-8253-EXT)

Engineered for leveled and lifted Duramax trucks, this extended travel CV axle delivers up to 47 degrees of articulation versus the factory's ~23 degrees, drastically reducing bind and premature failure. Upgraded internals, an 8-ball CV joint design, and thermoplastic elastomer boots deliver superior durability across extreme conditions. Backed by a lifetime replacement warranty to the original purchaser.

Requires 34mm socket for CV axle nut removal.

Axle shafts are thicker than stock, potentially conflicting with aftermarket coilover shock lift kits.
