South Bend Clutch OFE Clutch Kit with Flywheel

The South Bend Clutch OFE (Organic and Feramic Endurance) series is an industry-proven clutch system built around a proprietary hybrid friction technology that delivers serious torque capacity without sacrificing everyday drivability. A staple in the performance clutch market since the era of the 12-valve diesel, the OFE line has earned its reputation across diesel trucks, American muscle, sport compact, and European performance platforms alike.

Hybrid Organic/Feramic Friction Technology:

At the heart of every OFE kit is a unique dual-facing clutch disc that combines two complementary friction materials in a single full-face design. The Feramic facing — a sintered iron compound with graphite impregnation — delivers aggressive initial bite and exceptional thermal resilience under sustained heavy loads, while running cooler and more flywheel-friendly than full ceramic alternatives. The high-metal-content organic facing on the opposite side provides smooth, controlled engagement during low-speed maneuvering, towing, and daily driving. Together, these materials produce a clutch that holds firmly under power without the harsh, grabby characteristics associated with full-ceramic or full-Feramic designs.

What's Included — Complete Matched System:

• Hybrid dual-facing clutch disc — full-face Feramic and organic facings on a single marcelled disc for progressive, dual-dampened engagement
• Modified performance pressure plate — optimized clamp load and fulcrum geometry for smooth, consistent pedal feel and engagement
• Sprung hub design — heat-treated, wear-resistant hub absorbs driveline shock and protects transmission synchros and internal components
• Matched steel flywheel — low-carbon, hot-rolled steel manufactured to precise step height and surface finish specifications for ideal friction material compatibility and warp resistance
• Complete hardware — throwout bearing, pilot bearing, and alignment tool included for a full bolt-in installation
• SFI-certified manufacturing — built by a four-generation, SFI-approved manufacturer with decades of clutch engineering expertise

Purpose-Built for Performance and Drivability:

OFE clutch systems are engineered for drivers who demand both high torque capacity and real-world usability. These kits excel in modified diesel trucks that tow heavy loads, performance street vehicles with elevated torque output, street/track builds requiring superior heat management, and endurance applications where long-term reliability is non-negotiable. The OFE series delivers equally capable performance during daily commuting as it does under repeated high-energy use — offering superior torque capacity compared to many puck-style kits while maintaining the smooth engagement of a full-face design.

Installation and Break-In:

South Bend recommends verifying hydraulic system health, ensuring correct release bearing setup, and preparing the flywheel surface to the prescribed step height and finish specification prior to installation. A proper break-in period of normal stop-and-go driving is required to evenly seat the friction facings and establish long-term engagement characteristics. Correct installation and break-in delivers quiet take-off, a stable pedal, confident torque hold, and a clean release under heat.

South Bend OFE Clutch Kits with Flywheel are the proven choice for drivers who refuse to compromise between power handling and street manners — delivering professional-grade clutch performance engineered for real-world conditions.
