Great replacements
Outstanding bargain for the price. Installed on a 2000 Polaris Sportsman 500 4X4. The build quality looks and feels like it'll hold up, but only time will tell. These new ones fixed the wobbling issue the bad axles were causing. The bad ones had torn boots and were clicking when turning. The new ones fit as advertised and they are working perfect so far. They come with new spindle nuts, so that's a nice bonus. Lightly grease or apply anti-seize on the splines of the shafts to help prevent rust and help with install.

Would Buy Again
Perfect Fit and Smooth Performance!
I used these to replace the worn-out factory axles on my Polaris, and they have been working great. If you do any real trail riding or utility work, you know how much abuse the stock CV joints take over time. These premium assemblies feel heavy-duty and restored that smooth, confident ride immediately.
What I Like:
Exact Fit: No struggling during the install. They matched up perfectly with the factory specs and slipped right into place without any alignment issues. Complete Assembly: Getting both the rear left and right sides together makes it easy to knock out the whole backend maintenance at once. Solid Build Quality: The CV joints feel incredibly sturdy, and the boots seem thick enough to handle mud, brush, and rocks without tearing easily.
If your older Polaris is starting to click or pop in the rear, this set is an excellent, cost-effective replacement to get it running like new again!

Forged High-Strength Steel Driveline Refresh Built for Tough Mud and Trail Loads
Replacing worn, clicking rear axles on a classic Sportsman 500, 400, 335, Worker, or Diesel 445 quad is painless with this matching driver and passenger side set from AXLCORE. The build quality of the forged steel shafts is pristine—featuring precision-machined splines and premium, grease-packed CV joints that operate smoothly under heavy suspension flex (replaces OE# 1380142). The heavy-duty neoprene boots shield the joints from trail sticks, mud, and water.
Installation Time: Replacing both rear CV axle shafts takes about 45 to 60 minutes total using standard shop tools and an axle nut socket.
Trying to buy replacement axles individually through a local dealer parts catalog can cost an arm and a leg. This complete driver and passenger side pair is a fantastic bargain for the price.
