Troy and team (family) are the “real” deal for ALL your engine work/builds. Don’t hesitate run don’t walk to this establishment immediately. Denver is lucky to have a winning guy like Troy heading up our race engine build community. I can’t say enough about this top team.

The guys at Hipro are best in class. They go above and beyond. they provide incredible quality. I have had multiple blocks and valve jobs completed by them. every time they have exceeded my expectations. do not use anyone else the guys are so amazing

Highly recommend, preformed a complicated aluminum cylinder head repair and balanced a crankshaft for me. Quality work done correctly and at a fair price.

Very good customer service as well as excellent craftsmanship. Highly recommend. Both Troy and Ollie are great to work with.

These guys always do such a good job. Very friendly and knowledgeable

If you have machine work done on anything these are the guys, fair prices good turn around and honest.

I HAVE USED TROY FOR YEARS AND HAD NOTHING BUT THE BEST WORK DONE ON ALL MY MOTORS I HAVE BROUGHT TO THEM!!! I ALSO USE THEM FOR ALL MY SHOP WORK REBUILDING HEADS, BLOCK WORK AND ALL MACHINING THEY ARE TOP NOTCH GET RIGHT THE FIRST TIME EVERY TIME. SO THANK FULL TO HAVE A SHOP I CAN TRUST GREAT JOB TROY!!!!

I had them clean and check an Aluminum block. It came back dirty. I ended up pressure washing it myself. They said it passed a compression test. Once I put the block in it started over pressurizing the cooling system. It turns out the block had a crack in it and now I am getting the block back out and fixed. They are doing RTD engine work now and should not be used for your auto block needs. I found a much better shop to do my blocks.

I’ve had these guys do a few blocks of mine, and they always do it right for a fair price. I’ll be back!

Worst machine shop, they do not keep track of anything, will not call you back, always drag ass on projects. They have had a crank that i brought too them 2 months ago and they have yet to do any work or even give me a call back on the work they wanted to do too it. I do not recomend this shop unless you want to spend money and not know where it goes, or if you want your project to take forever. F+ Nice people bad service

Great people very professional

Best machine shop in colorado
