Description

The Hooker BlackHeart 71223012HKR is an automatic transmission mount spacer designed for LS engine swap applications. It is made of aluminum with a natural finish and black color. This spacer facilitates the installation of GM 4L60-4L70, Tremec TKO 500/600, or TTR-3550 transmissions when used with Hooker Blackheart transmission crossmembers.

This component is CAD modeled for optimal fitment and strength, and it provides the necessary powertrain inclination angles for compatibility with other Hooker Blackheart LS engine swap components. It is designed to work with Anchor Industries™ 2268 (rubber) or Prothane™ 7-1604 (poly) transmission mounts and includes attaching hardware.
