Needle roller bearing is a key part in a connecting rod kit. Low friction, high pressure affordability, and long durability are important characteristics for bearings. We provide OEM quality bearings in our connecting rod kit.
Besides, PEEK coating bearings are our recommended products for 4-stroke engines. PEEK is a soft polymer. And the PEEK coating layer absorbs debris in the engine oil to protect conrod race and crank pin from scratched by debris. And the durability of conrod kit is then greatly enhanced.
