RH-Beam Connecting Rods

RH-Beam stands for reinforced H-beam. H-beam design is very popular due to the good strength and affordable price. The RH-beam is a stronger design based on H-beam from BW engineers. It’s designed for the enthusiasts who preferred H-beam rather than an I-beam without any compromise on performance. It suits for high horsepower and torque. The reinforced straight H-section, stronger structure, and enlarged mating surface make it capable of extreme loading.
