14011090 - Bow Tie Connecting Rod (5.70" long)


Heavy-duty Bow Tie connecting rods are engineered to withstand the stress and strain of racing. These premium quality rods are forged from tough 4340 steel which has been vacuum degassed to eliminate impurities. Dedicated forging dies are used for the two different center-to-center lengths to minimize rod weight. Fatigue tests have shown that Bow Tie rods can endure more than 10 million cycles at racing loads without failure! Unlike the bolts and nuts used in production connecting rods, heavy-duty Bow Tie rods are equipped with aircraft quality 7/16" bolts which thread directly into the rod fork. Alignment sleeves positively locate the cap on the rod. Bow Tie rods are machined for pressed wrist pins, and are shotpeened to enhance their durability.
Technical Notes: Bow Tie rods are designed for 2.10" rod journals. The crankshaft must be rebalanced when using Bow Tie rods due to the increase in reciprocating and rotating weight. Bow Tie rod bolts should be lubricated with 30 weight oil and torqued to 70 ft./lb.; recommended bolt stretch is .005-.006". Heavy-duty pistons are available with compression heights to match 5.70" and 6.00" long Bow Tie rods; see the piston section for part numbers. Replacement bolts, washers, and sleeves are also available; see listings .
