GM LS Engine Swap Kit Includes Engine Mounting Brackets BHS513, Clamshell Mounts BHSxxx, Poly Inserts 71221016HKR, Through Bolts 71223015HKR, and Transmission Mount 71223029HKR. Add some series torque and power to your Jeep Wrangler with a GM LS engine swap. These engine-mounting components 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.


  • Designed to use most of the stock engine frame mounts to minimize necessary fabrication
  • High arch design maintains upper control arm to frame clearance
  • Does not require the use of a body or suspension lift (when used with a 4L60E/4L70E and stock transfer case) to allow for budget friendly build options
  • Designed to install a GM LS engine (Gen lll, lV) with a TH350, TH400, 4L60E, 4L80E or 6L80 transmission into a 6 cylinder Jeep TJ/LJ chassis by mating them to the stock Jeep Wrangler NP231J transfer case with aftermarket adapter.
  • Does not require removal or replacement of the stock steering shaft support bracket for simplicity
  • Maintains the stock passenger-side offset of jeep 4.0L engine to prevent alteration of linkage and other associated parts
  • Works with stock, transfer case drop, or belly-tuck drivetrain installations allowing several design/component options
  • Compatible with the stock skid plate, or aftermarket transmission cross members and skid plates for convenience
  • Designed for use with Hooker BlackHeart LT swap headers for a complete swap solution
  • Includes “clamshell” style engine mounts and polyurethane inserts for trouble-free use and serviceability
  • All hardware included
