The H-shape Is used for its buckling strength and it also supports weight reduction. to 1mm. Compared to the genuine rod, Maruha’s power rod weighs 80g less (around 460g). ARP, #2000 bolts are used to ensure strength. The joint part of the big end's cap is produced by machining which gives it strength and helps the weight reduction. The small end is processed by full-floating through the bush. The inner diameter is 22mm used for Maruha’s turbo piston whereas the OEM is 20mm. An oil orifice is set up on top of the small end and the dripping oil becomes the lubricant. Maruha’s power rod controls the small end and the big end separately.
