These super-high-strength rod bolts for the Ford 1600 Kent engine have a 12 point head which is 0.08 ounce heavier than our other 12-point rod bolts (1.04 oz vs 0.96 oz). If your connecting rods are too close to minimum weight for comfort, these bolts can save you the cost of replacing the rods. Since the extra weight is mostly in the head of the bolt, it minimizes the stress on the connecting rod and rod bolts.
