Manley Toyota 2JZG Supra 3.0L Set of 6 H-Tuff Connecting Rods 15027-6

Manley’s H-Tuff connecting rods are crafted from premium 4340 forgings and adhere to the same rigorous standards trusted by their original equipment customers. Designed to outperform standard H-Beams, the H-Tuff series offers enhanced strength with heavier beams, making them ideal for high-boost and high-horsepower applications.

These rods bridge the gap between traditional H-Beams and the more expensive Turbo Tuff I-Beam rods, providing a cost-effective solution for users pushing the limits of conventional H-Beam designs. The H-Tuff rods are engineered with increased cross-sectional thickness in critical areas, resulting in improved durability without significantly increasing weight.

Each set is weight-matched to within +/- 1.5 grams and features perfectly round big and small ends. Bend and twist tolerances are tightly controlled to ensure precision. The rods come standard with 3/8” ARP 2000 bolts for added reliability. They undergo comprehensive heat treatment, stress relief, shot peening, and individual magnaflux inspections to guarantee top performance under extreme conditions.

For those looking to safely maximize power without stepping up to a full I-Beam rod, Manley’s H-Tuff connecting rods provide a reliable and robust solution. Recommended rod bolt torque with 30wt oil is 60 ft./lbs, with a bolt stretch specification of .0058” to .0062”.
