Overview

The GSP XD Xtreme-Duty CV Axle Assembly is engineered for upgraded performance in extreme temperatures and challenging conditions. Its heavy-duty center shafts are constructed from industry-leading alloy materials, providing 30% more strength than standard OE axles with added heat treatment for durability.

This CV axle assembly features precision-engineered cages and housings for reduced friction and smooth motion. It offers extreme temperature resistance, with premium grade boots and specialized Moly grease designed to maintain performance from -50°C to 248°C (-58°F to 478°F). The design supports superior articulation up to 50 degrees, beneficial for lifted vehicles.

Vibration-free performance is ensured through precision machining and balancing, delivering smooth operation even under extreme driving conditions. Heavy-duty, stepless ear clamps provide reliable sealing, keeping grease in and contaminants out.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
