Motor Mount Shim Kit

The MOROSO Motor Mount Shim Kit is a precision spacing solution for small-block and big-block Chevy engine installations. This six-piece set addresses a common alignment challenge in engine swap and rebuild applications where motor mounts require fine-tuning to achieve proper clearance and load distribution on the frame.

The kit includes three graduated shim thicknesses—1/16 inch, 1/8 inch, and 3/16 inch—each sized for standard Chevy bolt patterns. This graduated approach allows builders and technicians to dial in engine positioning incrementally without removing and reinstalling heavy powertrain components repeatedly. Proper shimming prevents binding in motor mounts, extends their service life, and ensures that engine vibration transmits evenly through the frame mounting points rather than concentrating stress on a single location.

Builders working on Chevy engine swaps—whether upgrading displacement, correcting legacy alignment issues, or transitioning between different engine generations—find this kit essential during final fitment. The shim set eliminates guesswork and prevents the costly mistake of over-tightening mounts to compensate for misalignment. This is standard practice in professional shops where engine positioning directly impacts drivability, longevity, and structural integrity.

Small-block and big-block Chevy platforms dominate the engine swap and restoration market, making this motor mount shim kit a practical addition to any builder's toolkit or shop inventory. The combination of multiple thickness options and proper Chevy bolt pattern compatibility makes it a straightforward solution for achieving correct engine geometry in tight engine bays.
