This heavy-duty constant velocity axle by A-Premium fits a wide range of Chevrolet, GMC and Cadillac 4x4 models from the late 2000s through 2020. Built to replace worn or damaged front axles, it includes the spindle nut and delivers the correct spline and length specifications so installers can swap with the original equipment quickly. It’s designed for front-left or front-right installation and is sold as a complete shaft assembly ready for bolt-on fitment where applicable.

Which vehicles will this CV axle fit?

This axle covers many GM full-size trucks and SUVs across model years where the original equipment used a 33-spline front axle with the same compressed length. It’s an aftermarket direct-fit option intended to match factory geometry on these four-wheel-drive models.

How does this axle assembly affect driving and maintenance?

Replacing a failing CV axle restores drivetrain smoothness, eliminates clicking or vibration under acceleration and ensures proper hub alignment. Using a correctly sized replacement also prevents premature wear on adjacent components like wheel bearings and seals.

• Reduces vibration and noise caused by worn CV joints or bent shafts
• Prevents leaks from torn boots by installing a complete assembly
• Simplifies service time with a bolt-on unit that includes the axle nut
• Maintains factory drivetrain geometry to improve longevity of related parts

What should I verify before ordering to ensure correct fit?

Confirm your vehicle’s model year, front-wheel drive orientation (4x4), and original part reference where possible. Compare spline count, compressed length and spindle nut thread to the axle being replaced to avoid returns and fitment delays.

• Check that your vehicle is a listed make/model/year combination (see fitment list above)
• Measure or confirm 33 output splines and 22.91-inch compressed length
• Verify spindle nut thread is M24 x 2.0 and that the ABS tone ring is not required
• Match reference numbers if available from your dealer or repair manual
