185MM TB48 P3

Technical Parameters

Product Advantage

• Six Friction Faces — Maximum Torque in a 185 mm Package

A 7.25 inch triple plate clutch​ delivers six working friction faces versus four on a twin plate, pushing torque capacity roughly 30–50% higher without growing beyond 185 mm. That is the key advantage: you gain the holding power of a much larger clutch while keeping the compact diameter and low rotational mass that fits the Patrol bellhousing.

• Engineered for 500-800 hp Forced Induction Builds

The TB48DE has a cult following in the Gulf, with turbo and stroker Patrols clearing 1,000 hp. At that level the limiting factor is rarely the engine — it is whether the clutch can hold launch torque without slip.

• Sintered Cermet Discs for Extreme Launch Heat

All three discs use competition-grade sintered ceramic-metallic material that maintains a stable friction coefficient through repeated high-rpm launches. Compared with organic discs that glaze and fade, this triple disc ceramic clutch​ resists thermal breakdown under the intense, short-duration heat of drag starts and hill climb runs, while the three-layer composite disc structure resists cracking under shock loading.

• Still Lighter Than a Large-Diameter Single Plate

Adding a third disc does increase inertia versus a twin plate, but this 185mm triple plate clutch​ remains substantially lighter in rotational terms than a 230 mm or 250 mm single plate of comparable capacity. That keeps throttle response sharp and reduces shock loading on the gearbox — a real benefit for a heavy Patrol that still needs to rev quickly out of soft sand or off the line.

Product Uses

• Drag Racing & High-Boost TB48DE Builds

This is the triple plate's home ground. Launching a 2.5-tonne Patrol on a prepared surface puts enormous shock load through the drivetrain, and a twin plate at its torque limit will slip right when you need repeatable 60-foot times. With six friction faces , this 185mm triple plate racing clutch​ holds full boost launches run after run without fade.

• Hill Climb & Sprint Events

Short, high-intensity runs with repeated hard acceleration suit the triple plate's high thermal mass. The clutch absorbs launch heat without the sustained-slip penalty that hurts it in crawling use, and the low inertia helps the engine pick up quickly between gears on tight, technical courses.

• Desert High-Speed Racing

For closed-course desert racing where the car runs at sustained high speed rather than low-range crawling, the triple plate's torque reserve handles big tyres, high gearing and prolonged wide-open throttle without heat soak. Ventilation is adequate at speed, making this a strong choice for competition Patrols built for fast, open terrain.

• Extreme Horsepower Street Builds

For the top tier of Gulf-built turbo and stroker Patrols, a twin plate is often the weak link. This 7.25 inch triple plate clutch​ provides the holding capacity to put that power down reliably, with a billet cover and forged flywheel engineered for the cylinder pressures and launch loads these engines generate.

• Professional Race Team & Workshop Programs

Teams value documented consistency above all. Every unit ships dynamically balanced, with identical pedal feel and release point across batches — essential when a team runs spare gearboxes and needs the clutch to behave identically between cars and events.
