A-Premium Front CV Axle Shafts Set of 2 — Fits 2007–2020 GM 4x4, OE‑spec splines

Set of two A-Premium front CV axle shaft assemblies engineered to replace the front left and right axles on select 2007–2020 GM 4x4 trucks and SUVs, complete with axle nuts and factory-equivalent spline and thread specifications.

If your Silverado, Sierra, Tahoe, Yukon, Escalade, Avalanche or Suburban is showing vibration, torn boots, clicking while turning, or visible axle damage, replacing both front axle shafts with a matched pair restores driveline balance and simplifies installation. These A-Premium shafts are built to match OE spline counts, compressed length, thread sizes and bolt patterns so they fit directly into compatible front hubs and steering knuckles without modification.

Which vehicles are these A-Premium axle shafts compatible with?

These axle shafts are manufactured to fit a range of GM full-size trucks and SUVs with four-wheel drive across model years listed below. Confirm fitment by cross-referencing your factory part number or vehicle-specific fitment information before purchase.

How does choosing a matched pair affect installation and vehicle performance?

Replacing both front axles as a matched pair helps maintain equal torsional stiffness and reduces the chance of vibration or uneven wear after installation. It also simplifies alignment of axle splines and hub components during reassembly.

• Balanced driveline reduces vibration and noise under acceleration or turning
• Mated pair prevents mismatch in length or spline engagement between sides
• Saves time vs. staging two different aftermarket parts across months

What should I check before ordering to ensure fit and compatibility?

Verify your vehicle’s year, model, drive type (4x4), and whether factory ABS tone rings were used on the original axles. Cross-check the reference numbers listed with your OEM part number to avoid returns.

• Confirm model year and 4x4 designation match your vehicle
• Compare OEM reference numbers: 15185911, 15868123, 20909191, 22791460, 661430, 66-1430
• Note ABS ring absence; if your vehicle requires it, order accordingly

Who this is for: This A-Premium set is meant for owners, mechanics and fleet managers replacing worn or damaged front CV axle shafts on compatible GM 4x4 trucks and SUVs from 2007 through 2020 who want a direct-fit, matched pair with OE-style spline counts and hardware included. It suits anyone seeking a durable replacement that installs with standard hub and spindle specifications, provided the vehicle does not require an ABS tone ring on the axle.
