Product description
The South Bend Dyna Max 13" Upgrade Clutch Kit (13125‑OFEK) is engineered to boost towing performance and durability in Dodge 5.9L diesel trucks. Built with robust steel construction and a modified pressure plate for increased plate load and smoother engagement, this kit solves the premature disc failures common in high‑horsepower, heavy‑hauling 5‑speed and early 6‑speed non‑ETH 12.25" clutches. Featuring a half‑organic, half‑feramic disc, it’s rated for 475 HP, 1000 ft‑lbs of torque, and up to 25,000 lbs of towing capacity. Designed as a complete upgrade—not for stock applications—this clutch delivers the strength and reliability needed for demanding workloads.
