REDS 32mm Tetra 4 Shoe Adjustable Clutch System

REDS Racing offroad clutch system has been developed to make the engine power output more linear and smoother. The REDS clutch is guaranteed to provide the best traction, vehicle drive-ability and low fuel consumption. REDS clutch system is completely adjustable. You can choose different combinations of spring diameters, clutch shoes and flywheels. REDS clutch system is 100% made in Italy and comes pre-assembled to guarantee the best performance and reliability.

REDS new clutch system comes with 3 preload adjustments on the front plate to fit any type of ground and engine output. You can change the spring preload on the front plate from H to M and to L (High, Medium and Low position). The 1.1mm spring was introduced (available as an optional part) to further increase the number of setup combinations to best suit your driving style and track conditions.

The new 7075 Aluminum and Carbon clutch shoes have been redesigned to increase wear resistance. In addition, the new shoes are lighter to allow and engage at higher revs and lower inertia to rotation. You can use the clutch with the standard 2x Alu and 2x Carbon configuration for most tracks or 3x Alu and 1x Carbon for high grip conditions.


REDS clutch system is available both with 32mm and 34mm diameter to make it suitable for any type of car (Buggy and Truggy). 32 mm for Kyosho, JQ, Team Associated, Hot Bodies, Serpent, Xray. 34 mm for Mugen, Team Losi, Agama, Tekno. The original REDS bell can be used with all types of cars named above. Only TEAM LOSI car requires the original LOSI bell. 


XH and XXH front plates have been specifically developed for the truggy class and available only as option parts. All front plates have been redesigned to make assembly easier and last longer with either the 1.0 and 1.1 mm springs.

REDS has introduced new flywheels (available as an optional part in 32mm and 34mm diameter) with different inertia to adjust acceleration and engine torque. The available flywheels are:

  • High Inertia: low acceleration, recommended for low grip (optional)
  • Medium Inertia: good all around setup (standard flywheel)
  • Low Inertia: high acceleration, recommended for high grip (optional)

SCROLL DOWN for REDS standard vented clutch bells.

All REDS Clutch systems require a standard bell, which we sell. The Losi clutch bell is a proprietary length and will not work on our clutch system or anyone else's for that matter.
