Scuderia Car Parts supplies genuine McLaren clutch components sourced directly from OEM manufacturers. McLaren's Seamless Shift Gearbox — the SSG dual-clutch transmission fitted to the 570S, 600LT, 720S, 750S, 765LT, and GT — and the SSG II unit in the Artura both use wet multi-plate clutch packs that are fundamentally different in design from the single-plate dry clutches found in conventional performance cars. Getting these components right matters: the SSG's clutch packs are precisely calibrated to the transmission's adaptive shift logic, and non-OEM replacements can compromise both shift quality and reliability. Our team understands the technical requirements of McLaren's transmission systems and can guide you to the correct component for your specific model and gearbox specification.

Unlike a conventional manual or automated single-clutch gearbox, McLaren's Seamless Shift Gearbox uses two wet multi-plate clutch packs to pre-select the next gear while the current one is engaged, enabling shifts that are completed in milliseconds with no interruption in drive torque — a system derived directly from McLaren's Formula 1 technology. The clutch packs operate in a bath of transmission fluid, which manages heat generated during clutch engagement and provides lubrication to the friction faces. The friction material specification, pack preload, and plate count are all defined by McLaren for each transmission variant, with the SSG II in the Artura further refined to integrate with the hybrid powertrain's torque delivery. These parameters are not interchangeable between transmission generations, and the clutch pack characteristics directly influence how the gearbox's adaptive software manages engagement.
Because the SSG clutch packs are wet systems enclosed within the transmission, visual inspection is not possible without gearbox removal. Symptoms of clutch wear or fluid degradation include hesitation during power-on upshifts, slipping under sustained load, and in advanced cases, a loss of drive on one or both clutch circuits. McLaren specifies transmission fluid change intervals that are particularly important on vehicles used on track, where clutch temperatures are significantly higher than in road use. If the vehicle has been used with repeated standing starts or sustained high-load driving without fluid changes, clutch wear will accelerate accordingly. The SSG's adaptive learning parameters should be reset following clutch replacement to allow the transmission software to recalibrate engagement points to the new components.
McLaren OEM clutch kits are specified to the friction ratings, plate dimensions, and material properties that the SSG or SSG II transmission was designed around. Non-OEM clutch packs with incorrect friction coefficients or plate geometry will prevent the transmission's adaptive shift software from calibrating accurately, leading to compromised shift quality that cannot be corrected through software adjustment alone. On a dual-clutch system, the consequence of incorrect clutch specification is not confined to premature wear — it can affect the smoothness and consistency of every gear change the vehicle makes. For the Artura, the interaction between the SSG II clutch packs and the hybrid torque fill adds a further layer of specification dependency. Scuderia Car Parts sources genuine McLaren OEM clutch components through established manufacturer relationships, ensuring full compatibility with the transmission system.
