      Description

      Premium Power. Looking for more power from your 4.2L YJ? Scat's 9.6:1 Stroker kit is just what you need for a more engaging drive. This rotating assembly is complete and internally balanced to retain stock stroke. This rotating assembly with overbore pistons will give you a smooth ride.

      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 3/8" 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 a new level of power.

      Installation.
      Upgrading with a stroker kit is an intense 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 require boring from 3.75" to 3.905" to accommodate the larger pistons.

      Application. This 9.6:1 Scat Stoker Kit is designed for use on 1987-1990 4.2L Jeep Wrangler YJ models.
