Upgrade your Yamaha YZ250F or YZ450F with the WORKS Elite Axle Block Kit designed for precision and performance. This kit includes a pair of CNC-machined Elite axle blocks, a titanium drive-side receiver, and a square removal tool nut, transforming your stock fixed rear axle into a floating system used by professional racing teams to enhance traction and straight-line stability. The floating axle design ensures better weight distribution and improved handling under aggressive riding conditions, giving you a competitive edge on the trail or track. The integrated caliper receiver post on each axle block allows for accurate measurement and alignment, ensuring the chain and sprocket are perfectly aligned, which extends the lifespan of these components and maintains optimal power transfer. Manufactured from high-quality 6061 T-6 billet aluminum, these ultra-slim, precision CNC’d parts are built to tighter tolerances than OEM components, providing reliable performance and durability. The reversible design prevents the axle adjustment bolts from extending beyond their service range, simplifying maintenance and adjustments. Each axle block features laser-engraved ‘WC’ logos and is anodized in your choice of blue, red, black, green, or raw silver, offering both style and corrosion resistance. Made in the USA, this kit is a perfect upgrade for riders seeking factory-level performance with easy installation and precise alignment.
