HOOKER BLACKHEART PREMIUM LS/LT SWAP MOUNT BRACKETS - REAR BIAS POSITION

Fits GM 1988-1998 C1500 RWD Trucks

Part # BHS554
Hooker BlackHeart application-specific LS/LT swap engine mounting brackets eliminate the installation guesswork and compatibility uncertainty that comes with using universal swap plate mounting methods. These mounting brackets are available with forward-bias, or rearward-bias engine mounting positions that optimize powertrain placement based on user-selected transmission, transfer case and driveshaft compatibility/retention priorities. The factory transmission crossmember is re-used with these mounting brackets (cost savings since driveshafts and crossmember are re-used). Factory LS Vortec exhaust manifolds can be used along with the engine mounting brackets and are required to support a street-legal engine change (with catalytic converters). Off-Road racing applications can use Hooker BlackHeart BH13272 Gen-V LT Swap Headers. Mounts feature a black powder-coated finish and Include (2) engine mounting brackets, attaching hardware and instructions.

  • Premium Engine Mounting Brackets – for Two-Wheel Drive 1/2-Ton Trucks
  • Premium Engine Mount Brackets are Used with Hooker Blackheart Clamshells (71221018HKR for LS engines, or 71221019HKR for LT engines) with Through Bolts 71223015HKR, and Poly Inserts 71221016HKR (Black) or 71221017HKR (Red)
