      Very affordable for engine parts

      I was expecting for my 4.6 i6 rebuild to bankrupt me, and while it wasn;t cheap these std length pushrods saved me a lot of money. Its been 2 months and I havent had any bending or wear. 5/5 strrs

      Perfect fit!

      Fit like a glove. This was the exact size to replace the original old, brittle one. Would definitely buy again.

      Exhaust gasket

      This flange gasket was a literal life saver. The exhaust would run you out of the Jeep while idling. Glad I changed this

      Valve Cover

      This was perfect, bought one from a local car store here and it wasnt thick enough so oil was leaking. This one was thicker and easier to put on

          The videos outlining the capabilities, specs, and installation were instrumental to my decision on purchasing this winch. The website is well laid out which makes navigation a breeze. Friendly Customer Chat Support is helpful and appreciated as it provides a human connection for an otherwise cold internet transaction.
