Carbon Racing Clutch Ford GT GTE/GTLM

Designed to make a
difference

ZF Race Engineering's SACHS motorsport clutches have stood for top-tier quality in international racing for decades. The ambition: continuous improvement and the drive to keep pushing the limits. From the lightest clutch used in Formula 1 to proven twin-plate and multi-plate systems in WRC, DTM, NASCAR, Le Mans and the Dakar Rally - ZF Motorsport technology is a core component of many winning cars worldwide.

SACHS Carbon Racing Clutch
for Ford GT GTE / GTLM

The Clutch of Competence

Vehicle-specific for the Ford GT GTE / GTLM (model years 2016–2019): the three-disc SACHS RCC 3/140 carbon racing clutch delivers maximum track performance with minimal diameter and the lowest moment of inertia - ideal for LM GTE/GTLM regulations, the carbon monocoque layout, and the twin-turbo character of the 3.5 L EcoBoost V6.

ZF Race Engineering brings top-tier technology from Formula 1, Super GT, and WRC to the Ford GT's GTE/GTLM application. Focus: low weight, ultra-low inertia, and high thermal stability - for consistent, repeatable performance over long stints in WEC and IMSA.

The RCC 3/140 meets the Ford GT GTE/GTLM's demanding requirements: precise launch and shift response, stable friction levels in high-temperature windows, and strong reserves in endurance racing - from the 24h debut at Le Mans to IMSA endurance classics.

A system mass of just 2.17 kg and a low moment of inertia of 0.00687 kg·m² enable rapid rev-matching and short shift windows. In this specification, up to 1,180 Nm of maximum engine torque can be transmitted - optimally matched to the BoP-shaped torque profile of the EcoBoost V6.

Benefits

maximum thermal resilience - carbon quality from Formula 1

very low weight and minimal moment of inertia

smooth and comfortable launch behavior

no flywheel wear

extreme durability - up to 4x longer than conventional sintered racing clutches

Lowest mass

One of the major strengths of a carbon racing clutch is its low mass and the resulting low moment of inertia.

They are designed for the lowest possible mass with the goal of transferring engine torque to the gearbox as quickly and directly as possible.

Lightening measures in the cranktrain that reduce the moment of inertia increase vehicle acceleration noticeably in the lower gears.

Faster acceleration

If, for example, the clutch has a moment of inertia (Mtm) of 0,061 kgm2, with a gearbox ratio of 13,4:1 (first gear ratio) this acts at the drive wheel with 180 times the value (13,42). Converting Mtm into vehicle mass results in an additional weight of approx. 145 kg in 1st gear that must be accelerated.

Thanks to the extremely low inertia of the SACHS carbon clutch, shift times are significantly reduced and the vehicle accelerates faster.

Maximum service life

For carbon clutches there are pressure plate and shim packs available that compensate carbon wear. With these compensation pressure plates the clutch can be reset to as-new condition - significantly extending service life.

Each unit undergoes stringent quality checks and is individually tested and measured before shipment. Preload force, installation height and release characteristics are documented. The preinstalled carbon stack thickness is also recorded - the included document supports maintenance and the shimming process (compensation pressure plates for refurbishment).

Clutch Cover (Housing)

High-strength forged aluminum for maximum stiffness at minimum weight. The housing geometry supports efficient heat dissipation and stabilizes the clutch pack temperature window - matched to thermal loads in GTE/GTLM endurance racing (WEC & IMSA).

Material: Carbon

Carbon offers high temperature resistance, consistent friction across a wide operating window, and fine controllability even at elevated disc temperatures. Low density reduces inertia and drag torque; good thermal conductivity promotes fast temperature stabilization - advantages in sprints, tight circuits, and 24-hour events.

Hub Spline Profile

Vehicle-specific hub spline profile: the RCC 3/140 is delivered with the correctly matched spline for the Ford GT GTE / GTLM (2016–2019) - precisely matched to this model's gearbox input shaft. This ensures maximum fit accuracy, reliable power transfer, and durability in competition. Custom solutions are available on request.
