Compack 4 Pro B10 Steel Clutch

This is the COMPAK 4 Pro B10 Aluminum Clutch for 1/8 scale off-road cars, the adjustable clutch with 4 pads that redefines the concept of an adjustable clutch. It introduces a unique adjustment system in the market that allows you to modify the clutch hardness with the engine mounted and the car fully ready to roll.

The COMPAK concept, like its predecessor, refers to clutches that are installed on the engine fully assembled.

Smoother acceleration and greater stability

Thanks to the increased weight of its assembly (with a difference of 13 g compared to the lightweight version: 22 g in steel versus 9 g in aluminum), this clutch offers key advantages on the track:

Smoother acceleration: Ideal for bumpy, broken, or low-grip tracks.

Optimized cornering: Allows you to maintain speed more easily and intuitively during the layout.

More stable idle: Its greater rotating mass ensures more consistent and regular engine behavior.

Adjustment in seconds

By simply turning the car, locking the flywheel, and moving the regulator to the desired position, you can select from three levels of hardness (I, II, III) laser-etched on the flywheel itself. An innovation that minimizes clutch adjustment time.

Position "I" corresponds to the lowest hardness or mounting position, while "III" is the highest hardness. To check the selected position, just see which number aligns with the regulator's adjustment hole.

Universal system and compatibility

The 33 mm flywheel has been carefully designed to offer compatibility with most brands on the market. Additionally, the assembly has been designed to fit precisely with ULTIMATE bells. Note: Other bells on the market may not fit this clutch.

Intuitive and simple assembly

Thanks to its innovative design, assembling the COMPAK is as easy as pressing the springs with your fingers into the assembly position. A quick solution for drivers looking for simplicity without compromising performance.

Guaranteed longevity

The springs can be relaxed by placing them in the mounting position I after each training or competition day, preventing deformation over time. This detail extends the lifespan of the components and ensures consistent performance race after race.

Aluminum pads with wear indicator

The four aluminum pads incorporate a linear recess that acts as a visual indicator. When wear erases this mark, it's time to replace them, ensuring you never compromise traction or reliability. It is recommended to change the springs along with the pads to maintain optimal balance.
