What customers say

Trusted by builders & everyday drivers.

Reliable, high-quality service that gets the job done right. Here's what people across the Sacramento area have to say.

★★★★★

"Took my cylinder heads here after another shop messed them up. RVJ got them dead flat and sealed perfectly. Honest, fast, and clearly know engines."

Mike R.Roseville, CA
★★★★★

"30 years of experience really shows. They walked me through the whole rebuild and the engine runs better than new. Wouldn't go anywhere else."

Dave T.Auburn, CA
★★★★★

"Great communication and fair pricing. Had my flywheel resurfaced same week and the clutch feels brand new. Highly recommend this shop."
