ACT 99-02 Nissan Skyline GT-R (R34) Mod-Twin 225 HD Sprung Street

ACT Clutch Kits, Mod-Twin Clutches & XACT Flywheels Build a matched manual-transmission drivetrain with ACT performance clutch kits, replacement clutch discs, pressure plates, XACT flywheels and installation components. Black Ops Auto Works carries Advanced Clutch Technology parts for street cars, track builds and competition applications, including vehicle-specific single-disc kits and Mod-Twin multi-disc systems. Shop by exact ACT part number and your complete engine and transmission combination to find the right configuration for your build. Choose Your Part Start with the engine’s expected torque output and how the car will be driven. A daily driver needs predictable engagement, while a dedicated race car may prioritize fast shifts and repeated high-load operation. Compare the exact kit’s published torque capacity, pressure plate, friction material and hub design. ACT engine-torque ratings are measured at the engine; they should not be treated as interchangeable with wheel-t...

Shop clutch kits, flywheels, replacement discs and release-system components at Black Ops Auto Works. Compare ACT, Clutch Masters, Competition Clutch, Exedy, McLeod, XClutch, Action Clutch and other listed choices for a street refresh, a modified daily driver or a dedicated competition build. Choose the complete system around engine torque, use and the installed transmission.Street Engagement and Torque CapacityOrganic street-oriented discs, performance friction materials and different pressure-plate designs offer different engagement and pedal characteristics. Compare the actual manufacturer torque rating and its stated measurement basis with your build, including planned changes.A stage number is a manufacturer’s product-family label, not a universal horsepower range. An Action Clutch Stage 1 or Stage 2 reference, an ACT HD/Performance Street combination and a Clutch Masters FX-series kit must each be compared by their own specifications. Higher stage does not automatically mean a...

Shop multi-disc clutch kits, twin-disc clutches, and triple-disc clutch systems at Black Ops Auto Works. Explore application-specific packages from McLeod Racing, ACT, Clutch Masters, OS Giken, XClutch, and other brands represented in this collection. Compare street-oriented and competition configurations for compatible domestic and import manual-transmission builds, including modified engines that require additional clutch capacity. Twin-Disc and Triple-Disc Clutch Systems Multi-disc clutches use multiple friction discs within a matched assembly to provide additional working friction surfaces. This gives manufacturers another way to achieve torque capacity without relying solely on a larger single disc or increased clamping force. Disc count alone does not determine capacity, pedal effort, or street manners. Compare friction material, disc diameter, pressure-plate design, and the manufacturer’s intended use. A triple-disc system is not automatically the best choice for every high-o...

Shop drivetrain parts for maintenance, traction upgrades, transmission projects and performance builds at Black Ops Auto Works. Compare clutches and flywheels, driveshafts and axles, differentials and gears, mounting components and transmission-service hardware. Build a coordinated order around the transmission, axle and powertrain actually installed.Clutches, Flywheels and Release SystemsCompare ACT, Exedy, Action Clutch, Clutch Masters, McLeod, Competition Clutch, XClutch and other listed systems by application, torque requirements and intended engagement characteristics. Single- and multi-disc layouts are design choices; disc count or a stage name alone does not establish street manners or capacity.Match the clutch to the flywheel, input shaft and release system. A disc, complete clutch package, flywheel or hydraulic-release bearing supplies a different part of the job. Review retained components, required travel/clearance and the kit’s actual contents.Driveshafts and AxlesThe Dr...

Match the exact brake assembly and wheel clearance before selection. HKS Hipermax S and R coilover references distinguish chassis applications, and SPL R32 GTS/GTS-25/GTS-T tie rods specify RWD. AWD GT-R bushings and non-AWD/GTR Cusco bracing belong to their stated configurations.Clutches for Push-Type and Pull-Type DrivetrainsAction Clutch, ACT, SPEC, XClutch, Clutch Masters and OS Giken references cover different engine and gearbox combinations.
