It is a rear main seal kit for a gm vortec engine. It has slots made for a flat head screwdriver that make quick work of changing the main seal. The lip of the seal is different than a traditional rubber seal and the seal is narrower than the origional seal. It has an engine transplant. The plates are only 100 bucks and it saves a ton of extra work. The housing that the other gasket is for doesnt really need to come off if you are only doing the main.

The FELPRO gaskets and seals are just good quality. It is good as it gets as far as 2 piece main seals go. It comes with a little paper tab as well to help guide/feed the seal in and prevent cutting on the metal engine block. The front axle will hang down and give you room to get the pan off.

There's a little plastic tab that comes in this kit with no instructions. It provides logical instructions and a tool for installation. The "shoe horn" that comes with the seal works great to get the new top half started. It is a far better quality seal, and should be a standard for all jeep owners replacing the rear main oil seal.

• Comes with a little "shoe horn
• Come in handy to knock out the top piece
• Easy install, nice and beefy seal
