Manley Performance has made a significant improvement over traditional H-Beam connecting rods in the form of the new H-Tuff series for Chevrolet LS and LT1 applications. Engineered for high combustion pressure environments—including elevated boost supercharged and turbocharged engines—Manley’s new H-Tuff rods deliver exceptional performance at a very modest increase over standard H-Beam prices.

H-Tuff rods are forged from premium aircraft grade vacuum degassed 4340 steel alloy with increased cross-sectional thickness in all critical areas. Additional reinforcement comes from a double-ribbed pin surround. With all of that, they’re only about 25 grams heavier than a standard H-Beam rod at approximately 680 grams.

Equipped with 220,000 psi 7/16″ ARP 2000® rod bolts, Manley H-Tuff LS/LT1 rods are rated for 1,000 flywheel horsepower in drag racing applications (or more, depending on RPM, stroke, piston weight and power-adders).

Additionally, the rods are heat-treated, stress-relieved, shot-peened and 100% magnafluxed. The 6.125″ length rods (.025″ longer than stock) come in weight matched sets ± 1.5 grams. For details visit www.manleyperformance.com 

A Fuel Altered and a Doorslammer were the only two racing vehicles Richard Hartman hadn't driven in his career.

Since doorslammers don't burn nitro, for the crew chief of Funny Car icon Tim Wilkerson, the choice was an easy one. https://t.co/9tCNPbpF1d
