Pignonnerie de boite Renault JB3

We offer you these high-quality gearbox sprocket kits. This product allows you to change your gearbox sprockets during a refurbishment, a change after breakage or in the case of advanced engine preparation.
Unless otherwise stated, the gearbox ratios of this kit are identical to those of the original gearbox, but the solidity and reliability are much more important.
The gearbox being the link between the engine and the drive wheels, it absorbs and transforms the engine torque. It is an element that is heavily used in motorsport, so during advanced preparation, or simply for very intensive use, it is strongly recommended to strengthen the solidity of your gearbox.
Changing your original sprockets with reinforced sprockets will bring increased reliability to your vehicle.
