Description
A Quality Seal. Gaskets, in essence, are used for properly sealing engine parts as well as preventing leaks that can cause damage to the engine. When your engine gaskets start leaking, replace them with the Upper Engine Gasket Set. This gasket set includes Head Gaskets, Intake Gaskets, Exhaust Manifold Gaskets, Valve Cover Gaskets, and Valve Stem Seals.
Durable and Long-Lasting. These gaskets are built from highly-durable materials that are guaranteed to endure an excessive amount of heating and cooling cycles.
Installation. This engine gasket set is a direct-fit replacement of the original factory parts so they will install the same way as the stock equipment and do not require major modifications.
Warranty. A limited 12-month/12000-mile warranty, whichever comes first, covers this product against manufacturing and material defects.

Review shared from Engine Rocker Arm Pivot Bolt (87-06 Jeep Wrangler YJ & TJ)
1980 Wrangler - jontheJL
No valvetrain rattle
My rocker arms perform as intended, with little noise of operation ever since I replaced the arms and hardware with a valve job. It feels as new as it came off the showroom floor

Review shared from Hexagon Nut; Flanged Lock (07-25 Jeep Wrangler JK & JL)
1980 Wrangler - jontheJL
Machined ok
This nut for my ‘11 Jeep Wrangler JK was an ideal replacement. It fit perfectly, and the flanged lock design ensures a secure hold that won’t loosen over time. The quality is excellent, and installation was quick and easy. A reliable part that gets the job done with confidence.
