Wearing out CV axles? DmaxStore has the solution.
This Extended Travel CV Axle Assembly is built to handle the real-world abuse Duramax owners put their trucks through, especially leveled and lifted applications. With up to 47° of articulation compared to the factory axle’s ~23°, this axle dramatically reduces bind, stress, and premature failure at increased ride heights.

The thermoplastic elastomer boots provide superior flex-fatigue resistance, excellent tear strength, improved water sealing, and better performance across extreme temperature ranges compared to traditional rubber boots. Internally, upgraded cages, races, and bearings ensure smooth, reliable operation even at maximum articulation—where most factory and aftermarket axles fail.

Unlike competitors that rely on 3-ball designs, this axle utilizes an 8-ball CV joint, distributing load more evenly for increased strength, durability, and long-term reliability. Backed by a Lifetime Warranty, this axle is designed to perform and last.

Features:

• Extended Travel Design - Allows significantly more plunge and suspension travel than OE axles, reducing bind in leveled and lifted set ups.
• Higher Articulation Capability - Nearly doubles the factory articulation, minimizing CV joint stress and failure at increased ride height.
• Thermoplastic Elastomer CV Boots - Superior resistance to tearing, cracking, water intrusion, and temperature related degradation compared to standard rubber boots.
• Upgraded Cages, Races & Bearings - Engineered for smooth operation and durability at extreme articulation angles.
• 8-Ball CV Joint Design - Distributes load across more contact points than the factory style 3 bearing joints for increased strength and longevity.
• Lifetime Replacement Warranty - Covered for the original purchaser.

Includes:

• 1 - CV axle shaft for left or right side
• 1 - CV axle nut washer
• 1 - CV axle nut, self locking

Optional:

• CV Hardware Factory length - If your truck has a CV Axle spacer that came with your lift kit, The factory length hardware will not work for your application. 
• Factory hardware has 15mm heads. Replacement hardware is 17MM head. There may be a clearance issue with some lift kits due to head size increase. It is recommend to utilize the factory hardware with lift kits.

Replaces Part#:

• GM 20875738

Notes:

• The Axles Shafts are thicker than the stock unit, this may cause clearance issues on trucks with aftermarket Coilover Shock Lift Kits.
• You will still need to run the CV axle spacers if your truck currently has them installed using the longer bolts from your original spacer/axle. 
• Make sure to use medium strength thread lock for reinstallation of CV flange bolts. 36mm socket needed for CV axle nut removal.
• Don't forget to throw on some flashy DmaxStore Valve Stem Caps while under the truck!
