  • Piston rings
  • Wrist pin
  • Circlips
  • Top-end gasket set

Great service, and prompt delivery. I would order again and recommend them to my friends.

The item arrived fast and in good condition. There however seems to be a glitch with the scale the first time we weighed something. After we shut it off and then back on it seemed to be OK.

So far so good!

Thanks my complete order is for a 2000 ford ranger 2.5 thanks
