Description
The Sparks Racing 975cc Big Block Cylinder Kit is a perfect big bore kit for any RZR 900 XP owner who wants to drastically increase performance without sacrificing reliability. We have designed custom connecting rods for this kit which optimizes rod geometry and are 80 grams lighter than stock to insure both performance and reliability. Most companies are not correcting the rod geometry when they spread the bores on their big bore kits so they simply offer you an HD stock geometry rod which still must endure extreme side-loads.
