Description
Premium Power. Turn your 4.2L into a power house with the Scat 9.6:1 Stroker kit. This rotating assembly is completely internally balanced and will give you more power by expanding your engine to 280 Cubic Inches. You'll see greater horsepower with this upgrade with a 9.6:1 compression ratio without boring out your engine.
Durable Construction. Scat takes great care and is dedicated to making sure their balanced assemblies are sized to the tightest possible specification. This high quality kit is comprised of 2 piece chromoly steel forged rods with 7/16" cap screw ARB bolts for the most reliable fit and are precision honed with diamond tooling for exact tolerances. Dowel capped pistons for precise alignment, a ground and polished crankshaft and all required oil rings are included for a fully complete kit to upgrade your Jeep to supreme power.
Installation. Upgrading to a stroker kit is an extreme process, requiring full tear down of your engine's rotating assembly. We recommend you have an experienced, professional mechanic install this kit. This stroker kit is internally balanced and does not require boring out your engine.
Application. This 9.6:1 Scat Stoker Kit is designed for use on 1987-1990 4.2L Jeep Wrangler YJ models.
