Engine machining is what we do. Not a sideline.
Clegg Automotive Machine is a dedicated engine machine shop in Orem, Utah, serving vehicle owners, repair shops, restoration builders, and performance enthusiasts throughout Utah County.

A machine shop built on craft
We started — and we've stayed — focused on one thing: doing engine machine work right. Block prep, head work, crankshafts, rods, flywheels. The unglamorous, exacting jobs that make the difference between an engine that survives and one that thrives.
Over the years, that focus has earned us a quiet kind of reputation. Local repair shops send us their machine work because they know it'll come back ready to assemble. Restoration builders trust us with one-of-a-kind cores. Racers bring us their next build before the last one comes off the dyno.
We're not the loudest shop in Utah. But we're proud of the work that leaves the door — and proud of the customers who keep coming back.
Four principles, every job
Precision First
If it can be measured, it gets measured. No shortcuts on tolerances.
Craft Over Volume
We'd rather do the job right than rush the next one out the door.
Customer Trust
Honest recommendations and clear communication on every build.
Technical Guidance
Decades of know-how, freely shared with the people who hire us.
