The REDS Racing 34mm Off-Road TETRA Adjustable 4-Shoe Clutch System is designed to make the engine power output more linear and smoother, so you can get the most out of your engine. 

The 4-shoe clutch is easy to adjust and thanks to a rotating front plate there�s no need to disassemble it or to change springs. When you do, you don't need any tool, just your hands. You can change the spring preload from L to H position or vice versa with three simple steps: pull out the front plate, rotate it counter-clockwise until you center the desired hole with the pin and push it in to the stop position. 

The clutch system is 100% made in Italy and comes pre assembled and tested to ensure the best performance and reliability. It is available both with 32mm and 34mm diameter to make it suitable for any type of car (Buggy and Truggy). 32mm for Kyosho, JQ, Mugen, Team Associated, Hot Bodies, Serpent, Xray. 34mm for Team Losi, Agama. The original REDS bell can be used with all the cars listed above, except for Team Losi. 

Hybrid Shoes 
The clutch system is made up of a hybrid 4 shoes system: two 7075 aluminum shoes and two carbon shoes which is suitable for every kind of track. 

Flywheel 
The lightweight flywheel has a low inertia to rotation to maximize engine power. Thanks to the 32mm flywheel design, it is possible to race on every kind of ground without danger of flaming out 

Vented Bell 
The REDS high performance vented clutch bell (not included) is manufactured with a special hardened carbon steel and high accuracy CNC machining. These features assure longer life to clutch bells, shoes and ball bearings.
