Precision CNC water-jet cut from .250 plate steel. These Patented Design motor mounts are for installing the 1999-2009 Gen III/IV LS series engine into 1973-87 2WD Chevrolet & GMC C10 Trucks, Blazers, and Suburbans. They are slotted for adjustability with engine placement in the engine compartment. Most aftermarket adapter plates that install the Gen III/IV LS series engine into older GM trucks do not position the engine in the correct location. These mounts allows the installation of TH350, TH400, TH700R4, 4L60E, 4L65E, 4L80, and any other combination of standard or automatic transmissions. Clears LS truck pans, no special oil pan is required to clear factory steering or frame. These mounts will allow you to move the engine forward up to 1 inch, and rearward up to 2 inches from typical locations. Welded and cooled in a jig to retain precision alignment. These mounts are rubber mounted and retain the factory engine mounts. Grade-8 hardware included.

 (raw steel not painted) Black texture powder coat is available.

*These mounts will clear low mount a/c but will not allow the engine to slide back, they mount against the a/c compressor bracket. They will clear low mount alternator but the amount of adjustment is limited.
