Light Weight Exhaust Rocker Arm, Honda 2004-Current TRX 450R/ER

Description The Sparks Racing Light Weight Exhaust Rocker Arm is an excellent way to decrease valve-train work load. This is a direct replacement for the stock rocker arm, and the less internal weight an engine has, the more efficiently it will run. All types of engines, especially ones with high pressure valve springs, benefit from installing this rocker arm. SKU: LWRH04450TRX
