Add some serious torque and power to your Jeep Wrangler YJ with a Gen III Hemi Engine Swap. These engine-mounting brackets are one part of a fully engineered swap system that provides maximum component clearances, ideal drivetrain geometry and clearance for swap headers & 3.00" high-tuck exhaust system. These engine mounts work together with the stock skid plate / transmission crossmember to mount the transmission & stock NP231J transfer case. The Gen III Hemi 5.7L factory truck oil pan & accessory drive system are recommended for this swap (these parts come on the donor engine when using the 2003-2008 5.7L Hemi truck engine). The 5.7L truck engine is an ideal engine choice for the Wrangler since it makes torque at a low RPM, right where it is needed for off-road use.
