Restoration grade parts for classic GP cars

The Serpent 802171 aluminium 21T pulley and shim set is intended for the vintage 720-09 200mm GP family and is a solid choice when refreshing older race cars.

Stiff aluminium design for reliable drivetrain behaviour

Aluminium construction reduces flex compared with softer materials while remaining light. The result is a tougher pulley assembly that helps maintain consistent gear engagement.

Prepared for direct replacement in 720-09 layouts

Made to match the Serpent 720-09 200mm GP chassis, this pulley and shim fit into standard mounting arrangements and simplify maintenance for historic models.

Can this part be used on tuned street setups?

It is designed around the 720-09 GP geometry. Many tuned setups will accept it, but check for clearance with aftermarket components before final fitment.

How long should this pulley last under normal running?

Longevity depends on use and maintenance; regular cleaning and inspection will extend service life. Replace the pulley if you see scoring or play developing.

Any tips for fitment and setup?

Ensure shafts and bearings are clean, fit shims to achieve correct mesh, and spin the assembly by hand to confirm smooth rotation before reassembling the car.
