TeraFlex HD Front Axle Housings are perfect for replacing bent, broken, or damaged axles in JK Wrangler/Unlimited Rubicon models. Can also be used as a direct bolt-on upgrade for Jeep owners looking to beef up the stock axles� weak areas. Our Bare HD Front Axle Housings feature a heavy-duty housing with axle tubes, bracketry, and forged inner knuckles as well as pre-installed inner seals and upper control arm bushings. Transfer your existing internal components (differential, ring and pinion) and outer components (stub shafts, knuckle assembly, ball joints, unit bearings, brakes, sensors) to the new housing! Requires new inner axle shafts. These 70in wide front axle housings must be used with 70in wide rear axle housings such as our Tera CRD60 HD Wide Rear Axle Housings (w/ Semi-Float Axle Shafts or w/ Full-Float Axle Shafts).
