    Premium Power. Upgrade your feeble factory 4.2L engine with the Scat 10.7:1 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 an over the top 10.7:1 compression ratio.

    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 YJ to supreme power.

    Installation. Upgrading to a stroker kit is an extreme upgrade and process, requiring full tear down of your engine's rotating assembly. We recommend you have an experienced mechanic install this kit. This stroker kit is internally balanced.

    Application. This 10.7:1 Scat Stoker Kit is designed for use on 1987-1990 4.2L Jeep Wrangler YJ models.

    How do you increase displacement without changing bore or stroke?

    JoeWolfe

    • This kit actually will require boring out of the cylinder walls to increase the displacement and allow this kit to work. As these pistons are .030" wider than the stock piston This is going to be amended on the site for future reference.
