White Box application-specific 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, rearward-bias, or dual 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). Off-Road racing applications can use Hooker BlackHeart BH13272 LT Swap Headers. Mounts feature a raw un-coated finish and Include (2) engine mounting brackets, attaching hardware and instructions.

Features:

  • Standard Engine Mounting Brackets – for Four-Wheel Drive 1/2-Ton Trucks
  • Standard Engine Mount Brackets (WB130051, WB130055) are Designed for Use with the Factory V8 Engine Isolators and Provide a Simple, Cost-effective Gen-V LT Engine Mounting Solution
  • Fore/Aft Engine Mounting Engine Position Options – Optimizes Powertrain Placement Based on User-selected Transmission, Transfer Case and Driveshaft Compatibility/Retention Priorities
  • Forward-Bias Engine Location Maintains the Stock Location of the Transfer Case and Driveshafts with 6L80/6L90 Transmission Installations in 4WD Applications
  • Rear-Bias Engine Location (Stock Bellhousing Plane Position) Allows an Existing Transmission Transfer Case and Related Driveshaft(s) to Remain Undisturbed, if Desired.
  • Standard Mounting Brackets are Engineered to Accommodate either Engine Location (Dual Mounting Positions)
  • Compatible with Hooker Blackheart BH13272 LT Swap Headers for Racing and Competition Applications
  • Factory Driveshafts and Transmission Crossmember are Re-Used with Engine Swap

Instructions for Part# WB130055
These engine mounting brackets have been designed for use with the V8 engine mounts that were factory installed on these trucks. Use of these engine mounting brackets on 4.3L V6 equipped trucks will require the factory V6 frame side engine mounts and brackets to be removed and replaced with V8 engine mounts. The factory front crossmember may need to be notched for oil pan clearance when using the forward engine position on 1973-1987 K10 Trucks.
