Tech Resources

Installing a GEN3 HEMI into this vehicle will require the engine to have a mid-sump oil pan. Use with BlackHeart Headers BH2358 (tested for correct fitment with these engine mounts). K-Member clearance will need to be performed to accommodate low mount A/ C compressors ( on 2009 & Up engines that came with VVT) Vehicles that came from the factory with a Slant-6 engine will need to swap out the K-member with one from a V8 engine. Use with Transmission Specific Transmission Adapter (sold separately) BHS534 A727 Transmission Adapter BHS535 NAG1 Transmission Adapter BHS536 8HP70 Transmission Adapter
