Product Information

Product Details
Part No. BHS539
Warranty Details (90 DAY REPLACEMENT IF DEFECTIVE)
The Hooker Blackheart transmission cross member hoop is part of the most comprehensive line of Gen III Hemi swap components available for the Mopar B-Body. The BHS539 Cross member Hoop allows the installation of the popular, NAG1 5-speed or 8HP70 8-speed automatic transmission when used with the corresponding adaptor plate (sold separately). The BHS539 Transmission Cross member Hoop replaces the very narrow factory Hoop on the original B-Body upper transmission cross member allowing adequate clearance for drive shaft coupler and Speed sensor tone rings. The BHS539 transmission Cross member Hoop is specifically designed to replace the factory hoop and when used in combination with the BHS532 transmission cross member will provide a bolt in clearance solution with OE (Original Equipment) strength and durability with no need for any fabrication or welding.

Product Features:
  • Engineered Transmission Mount System Works together with Hooker Blackheart Engine Mounting Brackets, Transmission Cross member, Long Tube Headers, and Exhaust Systems
  • Offers an Easy Trouble Free Gen III Hemi Engine Swap in the 1966-1970 Mopar B-Body
  • Provides the Necessary Clearance Through the Upper Transmission Cross member for the Drive Shaft Coupler and Speed Sensor Ring when Installing the NAG1 or 8HP70 Transmission
  • 1/2" Steel Upper Hoop Provides the Necessary Structural Integrity When Used in Combination with the BHS532 transmission Cross member (no Welding Required)
  • No Cutting of the Transmission Tunnel Required
  • Accommodates Popular NAG1 or 8HP70 Transmission (Requires Transmission Specific Adaptor plate)
