Belt cam upgrade for BD7/BD5/DRB

The Yokomo B7-BTC pack includes four resin belt tension cams made for 1/10-scale touring chassis. Fabricated in lightweight resin, these parts keep added weight low while enabling quick tension adjustments without replacing larger drivetrain hardware.

Installed on the belt route, the cams change take-up and tension points, giving a straightforward method to refine belt stability and the car's drive character. Fitting is familiar to anyone who has worked on belt-drive touring cars — remove the coverage plate and swap the cams following the chassis-specific instructions.

Practical notes: perform small tension changes and check belt runout and alignment after each tweak. Resin parts require care, so avoid overtightening nearby fasteners to prevent distortion. These cams are aimed at drivers who prioritise reduced mass and precise belt control on the listed chassis.

Do the four cams cover left and right sides

Yes, the four-piece set lets you replace or tune cams on both sides of the drivetrain so you can balance tension across the car.

How do resin cams compare to metal in durability

Resin offers a weight advantage but will generally be less abrasion resistant than metal; monitor wear and replace as needed for high-use applications.

Installation best practices for these cams

Fit the cams using chassis service steps, make small tension adjustments, inspect alignment after each change, and avoid overtightening screws beside the resin parts.
