Able to withstand up to 60,000 PSI, Speedmaster 746-1-261-011 roller rockers are the toughest and most innovative rockers we've ever made. Crafted from certified aircraft-quality, heat-treated aluminum, they're matched to massive, precision-ground trunnions for superior durability, and optimized rocker arm geometry evenly distributes the load for maximum strength. By utilizing oversized needle roller bearings, we were able to achieve superior load distribution and longer service life.
