Proper engine mounting is a fundamental requirement of performing any LS engine swap and Hooker now makes it possible to accomplish this task in any GM 4th-gen F-body without having to swap out the stock LT1/LT4 engine K-member for a factory or aftermarket LS K-member. These brackets are designed for bolt-in installation onto the existing LT1/LT4 engine cradles. LS Oil Pan 302-2 can be used with these mounts


  • CAD designed for optimized strength and fitment
  • Provides same-as-factory LS engine and transmission location and inclination angle
  • Specific mounting brackets for LT1/LT4 V8 equipped cars
  • Allows use of stock transmission crossmembers for 4th-gen F-body 4L60E and T56 installations
  • Fully compatible with Hooker 4th-gen mid-length headers and dual exhaust system recently developed for this vehicle platform (requires installation of LS1 steering rack)
  • Fabricated steel construction provides high strength at an affordable price
  • Compatible with stock GM or aftermarket rubber or polyurethane 4th-gen F-body LS engine mounts
  • Bracket-to-frame hardware included
  • LS Oil Pan 302-2 can be used with these mounts
