WORKS Blue Axle Blocks Elite, Size Not Specified, Model 17-280

Consisting of a pair of CNC’d Elite axle blocks, a titanium drive-side receiver and a square removal tool nut, the Elite Axle Block Kit converts your stock Off-Road or Dual Sport model’s rear axle from a fixed design into a floating type. Factory teams use this same floating type design on their race team bikes to improve traction as well as straight line stability and now those same benefits are available from this kit. Another key component is the integrated receiver post on each axle block that allows the use of a caliper to precisely measure and match the left and right axle block’s position. This assures exact alignment of the chain and sprocket so critical to prolonging chain and sprocket life.

The WORKS Elite Axle Block Kit, model 17-280, converts the stock rear axle on select Yamaha Off-Road and Dual Sport models from a fixed design to a floating type. The floating axle design is intended to improve traction and straight-line stability. The kit includes a pair of CNC-machined Elite axle blocks, a titanium drive-side receiver, and a square removal tool nut.

Each axle block features an integrated caliper receiver post for precise measurement and matching of the left and right axle block positions. This helps maintain accurate chain and sprocket alignment, which can help prolong chain and sprocket life. The ultra-slim axle blocks are precision CNC-machined from 6061 T-6 billet aluminum and manufactured with tighter tolerances than O.E.M. parts. The reversible design helps keep axle adjustment bolts from extending beyond their service range. Laser-engraved “WC” logos and a blue anodized finish complete the design.

The manufacturer part number is 17-280. The vendor part number is 66-17280. Fitment includes the 2012–2017 Yamaha YZ250F and the 2010–2013 Yamaha YZ450F. The product is made in the USA.
