(2 customer reviews)




Sparks Racing has been at the forefront of the ATV performance market for over 30 years, winning countless championships in all types of ATV racing. Sparks Racing founder, Curtis Sparks, built their reputation from years of racing, hard work, and dedication. Their company was started in a small shop in Lamont, CA and has grown into a world renowned manufacturer of ATV & UTV performance products. All of the people at Sparks Racing have been involved in racing or motorsports competition in one way or another, so they all share the same need for speed their customers have! Sparks Racing joined the UTV market in 2012 and is dedicated to producing quality and high performance parts for their customers.

The Sparks Racing Heavy Duty Head Stud Kit is a superior replacement for the stock head bolts and is a must for any RZR 900 XP/XP4 or RZR 1000 XP/XP4 running boost or high compression. The stock head bolts were not designed to take the abuse or control the combustion pressures of boosted or high compression engines, and Polaris recommends the stock head bolts NOT be reused. Replace your soft weak head bolts with a stud kit that can handle anything you throw at it! These studs are, also, long enough to accommodate most engines utilizing a spacer plate or longer cylinder.
