Gen 3&4 LS motor mount adapter brackets

Applications: Gen III and Gen IV LS motors ( LQ9, LMG, LC9, LQ4, LS1, LS2, LS3, LS7, LS9, LR4, LM7, L59, LM4, L33 LQ4, L76, LY6, LY2, L20, LH6, LY5, LMG, LC9, LH8, L92, L99, LSA) Probably a few we are missing since there are 40+ variants but you get the gist of it. 

What are the Gen 3 and Gen 4 LS motor mount adapters?

The LS platform uses a different motor mount bolt pattern than the earlier small block or big block GM motors, because of this an adapter is needed for these engine swaps. Our adapters are designed to work with our frame side motor mounts but they are pretty universal if you are doing something custom. One piece design to make everything super strong!

What frame side mount do these adapters work with?

We designed these to work with our Squarebody/67-72 frame side mounts, the two together will put the motor in the stock location. They can be used universally if you are working with a different application. They are designed to work with a 3" bushing assembly using a 9/16" bolt.

Note:  For LS motor swaps in 67-87 GM truck/suv the stock location of the A/C compressor can not be retained, there are many companies in the aftermarket offering up high A/C mounts. For trucks that are 4x4 crossmember it will clear if you are using a 4x4 pan on the motor. Some very rare occurrences based on frame tolerances (and super old frame rivets shifting) a notch of the crossmember or spacing up the mount a little may be needed.  On 2wd trucks the stock crossmember will be fine.
