Sparks Racing Heavy Duty Head Stud Kit, Polaris RZR 900 XP/ XP4 and RZR 1000 XP/ XP4

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.

Each Kit Includes:

• (6) Hardened steel studs

• (6) Hardened steel washers

• (6) Hardened 12 point steel nuts
