Hydraulic Kits

About

Hydraulic Kits Clutch hydraulics are the silent partner in every great shift, and this collection exists to make that partnership predictable. South Bend Clutch hydraulic kits—masters, slaves, lines, and pre-bled assemblies—are specified to deliver the stroke, pressure, and heat tolerance your clutch system requires, whether you’re running a daily-driven diesel truck, an LS street/track build, American muscle, a European performance car, a Jeep or off-road rig, or a sport compact platform. If you’ve ever chased “clutch problems” that turned out to be a tired master cylinder, air in a long line, or an out-of-range fork angle, you know why hydraulics deserve the same attention to engineering as the clutch itself. This collection brings together the parts and matched kits that restore full release travel, set correct engagement height, and keep pedal feel consistent as temperatures and workloads change. Release geometry is where hydraulics earn their keep. A pressure plate can be perfectly tuned for clamp, a disc can be the ideal compound and facing, and a flywheel can be dead-flat—but if the slave cylinder isn’t moving the release fingers far enough, you’ll grind into reverse, balk at high-RPM upshifts, and swear the clutch is “too aggressive.” Our hydraulic kits are spec’d around the total system throw required for clean disengagement, with bore sizes and lever ratios that maintain reasonable pedal effort. On platforms where OE hydraulics struggle with heavier clamp loads—common with dual disc upgrades, organic/feramic hybrids, and feramic towing kits—we size components so that release remains crisp without ballooning pedal effort or shortening the engagement window to a hair-trigger. Diesel trucks highlight the need for robust hydraulics because heat, towing, and long pedal cycles expose weak links. Our pre-bled master and slave assemblies for Cummins G56/NV4500, Power Stroke/ZF, and Duramax applications are designed to minimize sponginess, resist heat soak, and del
