Item received as described. Thanks.
A+++ seller, fast shipping, thanks a lot
Listing said still in manufacturers packaging. Received in a different box and was missing several gaskets. Guess I can't complain for half price.
Seller contacted me and is making it right. Also did a little more research and the piston was not the cheap piston that came with the kit originally, it had been replaced with a higher name brand piston. No complaints. Changed to 5 stars.
Installed this gasket kit on my TRX250. The fit was precise and the quality of the materials is excellent. It runs perfectly with no leaks. A great value for the price.
This gasket kit matches the OEM specs perfectly. The materials are top notch and it installed without any problems. A reliable part that performs just as it should. Very satisfied with the purchase.
