Testimonials

"Wanted to thank Scott for the extra technical direction. It gave me all the confidence in my 900 rebuild!"

Tom A.

" I couldn't be happier with the clutching for my RZR turbo
1000. I purchased both primary and secondary clutches and explained how
I use my UTV. The clutching is perfect, much much improved over stock
for what I needed. I would buy them again in a heartbeat."

Ken A Spomer.

"Did a RZR 900 to 1000 conversion and Scott was able to spec all the correct parts including some key upgrades to make the power I was looking for."

Jon C.

"Second RZR Engine kit I've purchased from MCB. First for my 800 and now My 1000. Killer parts, always goes together well and their Tech is the best!"

Jeff Weiler

"Real people with real experience and Professional! Good luck finding that these days.

Mike Detone - customer for life

"I'm a believer now. Tried 2 of the "other" brands of Durability kits both lasted less than 100 miles. Finally used MCB's kit and have over 500 on this kit!, WAY smoother running!"

George Ware - Colorado Springs

"I had my 2015 RZR 900 engine rebuilt by MCB's Engine dept. and after breaking it in we went on a 200 mile 2-day poker run. More power everywhere! Great work!"

Ralph W. - Taylor MI

"Sent both mine and my wifes etecs to Scott and the guys at MCB, outstanding service, and they both run flawless"

Keith and Mary Sensom - NY

"Best engines in the U.S. hands down!"

Jeff Dalich - Bozeman MT

"Had MCB build 2 engines this last fall and with over 1500 trouble-free on each miles I couldnt be happier"

Tom H. - Ohio

"Sent my 2012 Etec 800 to MCB and glad I did. Excellent communication, 2 week turn around and it runs better than when I bought it new!"

Stan Waterman - Wyoming

"500 SS build on their new dual ring pistons and crank kit. Great tech assistance throughout the process."

Pete - Michigan UP

“The guys at MCB have always been great to deal with and seem to always have the parts in stock ”

Mario Andretti Four Time Indy Car Champ

“I really appreciate Matt and his staff taking the time to answer all of my questions over the phone similar to what a good parts-counter person would do at a respected dealership. I also believe MCB Performance offers quality items at very reasonable prices. ”

Paul - Indiana

“For over 2 years, I have been purchasing snowmobile engine parts and accessories from your company, MCB Performance. You and all employees have great customer service, and knowledge of the products sold.”

Steve - Albany

"I am the owner/operator of Mountain Powersports in Central Point, OR and I use MCB pistons as an OEM replacement in most of my customers' engines and have very good luck with the product. Their service is great and prices affordable. I highly recommend their dual ring cast pistons as an OEM replacement in any snowmobile engine!"
