      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, 87-90 Wrangler YJ, 79-83 Cherokee / Wagoneer SJ, 79-87 J-Series Trucks and 84-86 Grand Wagoneer SJ models equipped with 4.2 liter six cylinder engines with 0.030-inch over-bore. Sold individually- use 6 per engine. Replaces OE 8134441.030. Piston 4.2L .030 1979-1990 Jeep CJ
