Description
Over time all internal engine wear surfaces become worn. This is true for crankshaft journals, connecting rods, camshaft lobes, piston rings, bearings, etc. When rebuilding a worn out engine you'll need to replace them all in order to regain the engine's original performance. And, let's face it, Jeep's need all the power we can get. We offer new high quality replacement engine parts to get your Jeep back on the road. This replacement piston fits 79-83 CJ5, 79-86 CJ7, 81-86 CJ8 Scrambler, 79-87 J-Series Trucks, 79-83 Cherokee SJ, 80-83 Wagoneer, 87-90 Wrangler YJ and 84-86 Grand Wagoneer SJ models equipped with 4.2 liter engines.

I got into Jeeps at an early age, as a child around 3-4 year of age my parts got me a power wheel Jeep and the rest was history. Growing up I always wanted a Jeep, from the day I started driving I spent my days behind the wheel of a Jeep branded vehicle, which has not changed.
