Dirt Tricks has developed a tool steel, heat-treated dome washer that develops two to three times the preload force of the OEM washer without reaching its elastic limit and without overstressing the mating components. This solves O-ring leakage as well as extending the life of both the countershaft and sprocket splines.
A countershaft replacement alone has labor costs in excess of $700. If you plan to keep your KTM four-stroke, this product is well worth the small investment for many reasons.
