• Dry Film Lubrication Coating on piston skirts for increased durability and reduced friction.
• Oversized Valve Pockets designed to work with oversized valves.
• WPC Hard Treated wrist pins for extreme durability.
• Double Pin Oilers provide twice the lubrication to the wrist pin.
• Anti Detonation Grooves limit the piston/cylinder contact under extreme temps and high RPM.
• Accumulator Groove collects excess blow by and residual gases during combustion and alleviates top ring flutter while increasing ring seal.
• X-Forging design enables the use of a shorter pin for added strength and overall weight savings.
• Optimized Cam and Barrel for tighter clearances, reduced noise, better ring seal, more power and increased durability.

The Holz/Kroyer Big Bore Kit is designed by Kroyer Racing Engines and distributed solely by Holz Racing Products.

Lynden, WA (May 8, 2009)- Holz Racing Products (HRP) and Kroyer Racing Engines (KRE) have announced a newly formed relationship which will bring the race dominating and reliable horsepower of Kroyer Racing Engines to the latest in Ranger RZR UTV performance offerings at Holz Racing Products. The relationship was announced after several months of testing and race wins by HRP owner Mark Holz in the World Off-Road Championship Series (WORCS) with his Kroyer Racing Engines powered RZR. Holz Racing Products will be the exclusive distributor for all KRE side-by-side related products.
The trophy case at Kroyer is impressive to say the least with nearly 10 years of proven, reliable horsepower, resulting in more than 30 titles in SCORE, Best-in-the-Desert and CORR competitions. Kroyer has also been recognized as a five-time NASCAR Engine Builder of the Year with three NASCAR West Championships to their credit.
“Partnering with Kroyer allows us to deliver simply the best performance products for our RZR customers,” said Mark Holz. “We’ve been testing many of the engine configurations in our race RZR this season and the results speak for themselves.”
Indeed, the KRE powered HRP Polaris RZR piloted by Mark Holz has captured 3 out of 4 wins in WORCS races and is leading the point battle; Holz also recently won the Terrible Town Best-in-the-Desert 250. Further proving the championship caliber of Kroyer Racing Engines, the KRE powered Walker Evans Racing Polaris RZR driven by RJ Anderson has also won 2 out of 3 M4SX events this season.
“We’re very excited about teaming up with Holz,” said Kevin Kroyer, owner of Kroyer Racing Engines. “Holz Racing is recognized as a leader in the Polaris RZR market for his suspension and chassis technology. Now together we can offer his customers an assortment of proven engine performance parts.”
