We have been using Racers Edge for several years now. They have always gone above and beyond our expectations. They have worked with us creating our custom label CNC heads, taken on projects that other shops wouldnt touch and ensured that our projects are capable of making more power than the competition. Bret and his crew have always stood behind their work and gave sound advice before the project started. Keep up the great work Racers Edge AZ!

They are awesome .. They are busy but are very helpful ...

Brett is an awesome guy, great place to get your attention or race motors worked on. Very knowledgeable staff

Its very busy, but well worth the wait. Its a place that you will have to see, and. Experience for yourself. I have been a fan for over 10 years👍👍

They are very professional,know there racing and i will be doong business there sooner than later

Took my cylinder heads to them for machine work. I was quoted three weeks and ended up taking 9 1/2 with zero communication!!!He swore up-and-down that he would provide me with a spec sheet and how the heads flowed, but never did. I could go on for days! Don’t use this shop!!!! Won’t return calls or texts, now.

Very friendly and thorough and did great work

Dropped engine parts off to be cleaned.They finished before the time they originally gave me and below the estimated cost.Friendly staffs well

Efficient, knowledgeable and reasonable! Rare attributes to find these days. Thanks to my neighbours for suggesting them.

If youre looking to have some serious work done to your quad or motorcycle check these guys. Honest, professional, and reliable. Best little performance shop in tucson. They can even dyno for you.

Best in the business. I send all my motors to John (from Texas) cause I know what I’m getting when he is done, always reliable and always fast!

One of my buddies recommended me this place, I see why . I took Johns word on what he would do to my quad to make run better and the work he did was amazing !! My 2018 yfz450r runs and sounds like a MONSTER ! Great customer service, and got it done in just a couple days. Super happy with the results!

Had them CNC my LS6 heads and they did an amazing job. Nice chunk of HP gained. Will be back for more.

Did a fantastic job on Maxys Africa Twin!
