Tusk is always a good product
Very satisfied with this Tusk gasket. The quality looks excellent, the material feels durable, and it seals perfectly. It arrived well packaged and matched the original specifications without any issues. Installation was easy, and everything fit exactly as expected. Great value for the price and a product I would definitely recommend.

Hot Cams Valve Shim Kit
Kenneth in AZ
Best thing ever for doing valve adjustments.
Was able to adjust the valves using the great assortment of shims. Best part now is that I won't be paying for a bucket shim saving big $$$$'s. Well worth the onetime investment and install.
