Fitment Notes:
- This crossmember is designed as an Integral component of the complete Hooker Blackheart LS swap system for this vehicle application. Its unique design geometry is designed for compatibility with Hooker Blackheart 12512HKR and 12613HKR engine mounting brackets only.
- Due to design variances in the crossmember mounting hole locations on GM 2nd-gen F-body subframes, the mounting holes in this crossmember may not line-up directly with the mounting holes in your subframe. In such cases, the crossmember will need to be mounted using angle brackets included with this crossmember (requires drilling new holes in the subframe).
- Direct installation of a T56 (GM F-Body/GTO LS versions only) or T56 Magnum transmission.
- 4L80E or 4L85E Transmissions REQUIRE Part Number 71223013HKR
- TH400 or 2004R Transmissions REQUIRE Part Number 12650HKR
- Note: this crossmember is not compatible with Tremec TR6060 transmissions
- Designed for use with 71223029HKR (black) or 71223030HKR (red) transmission mount
