185MM TB48 SPRING P3

Technical Parameters

Product Advantage

• Six Friction Faces with Torsional Damping — Power Without Punishment

This 185mm triple plate racing clutch with sprung hub​ combines the torque capacity of six friction faces with a genuine torsional damper in the disc hub. The arc springs absorb drivetrain shock before it reaches your gearbox, transfer case and axles You get competition-level holding power and​ the shock absorption that rigid race discs simply cannot provide on a 2.5-tonne 4WD.

• Protects the Gearbox on High-Torque Launches

Launching a heavy Patrol at full boost sends a violent torque spike through the driveline. In a rigid-hub clutch that spike lands directly on gear teeth and shafts; in this sprung hub ceramic clutch, the hub springs cushion it. For TB48DE turbo and stroker builds running big tyres and high grip surfaces, that damping is often what keeps a gearbox alive — and gearboxes cost far more than clutches.

• Competition Ceramic Compound, Now Drivable

All three discs use sintered ceramic-metallic friction material rated for extreme launch heat, maintaining a stable coefficient when organic material would glaze. Pairing that with a sprung centre makes this triple disc ceramic clutch​ far more usable than a rigid race unit: less idle gear rattle, smoother take-up, and a wider engagement window that tolerates imperfect rev-matching on the road.

• Far Less Idle Rattle and Cabin Harshness

Rigid race discs are notorious for gearbox rattle at idle and harshness at low rpm. The sprung hub in this 7.25 inch triple plate clutch​ dampens torsional vibration at source, noticeably cutting noise and harshness. That matters if your Patrol spends any time on the street — it is the difference between a competition car you can drive to the event and one that needs a trailer.

• Forged Chromoly Flywheel, 6061-T6 Cover, Deep-Nitrided Plates

Built around a 4140 forged chromoly flywheel, a CNC-machined 6061-T6 billet aluminium cover and a 6150 steel diaphragm, the assembly is engineered for sustained competition loads. Every steel component is deep-nitrided for hardness and wear resistance, and each unit is dynamically balanced so all three discs release cleanly together, lap after lap.

• Configurable Damper Rates for Different Builds

Damper springs are available in multiple rates, letting you match the clutch to the vehicle: softer rates for street and rally-raid Patrols that need shock absorption on corrugations, stiffer rates for circuit and sprint cars that prioritise response. Every kit ships complete with flywheel, cover, three discs, floater plates, bolts and spring hub.

Product Uses

• High-Power Street Patrol (500–800 hp)

This is the sprung triple plate's core market: a heavily turbocharged or supercharged TB48DE that still gets driven on the road. You need the torque capacity of a triple plate, but a rigid race clutch would make traffic unbearable and put the gearbox at risk. The sprung hub triple disc clutch​ holds the power while keeping take-up civil enough for real-world driving.

• Rally Raid & Cross-Country Competition

Long-distance desert events combine high-speed running with sudden load changes — landing after a jump, hitting a washout, powering through soft sand. Those load reversals shock the driveline. The sprung hub cushions exactly that, protecting the transfer case and diffs over hundreds of kilometres, while six friction faces handle the sustained torque a fully loaded Patrol demands.

• Drifting & Club Motorsport

Drift and club racing involve repeated clutch kicks and rapid load transitions. Rigid hubs transmit every shock into the transmission; this 185mm triple plate clutch with sprung centre​ absorbs it, letting drivers use clutch kicks more freely without destroying driveline components — while the ceramic faces handle the heat of continuous abuse.

• Desert Racing & Dune Competition

Fast desert running loads the clutch hard but rarely holds it in sustained low-speed slip, which suits a triple plate well. The damper helps on hard surface transitions and landings, and the low rotational inertia of the compact 185 mm package keeps the engine responsive when you need instant torque out of soft sand.

• Towing & Heavy-Load High-Power Builds

A tuned Patrol towing a large caravan or boat places enormous strain on the clutch at hill starts. The triple plate provides the holding capacity; the sprung hub prevents the driveline snatch that otherwise makes loaded take-offs violent. This combination suits expedition and tour operators running high-output engines with heavy trailers.
