Precision Pulley Mounting for Viper 989 GP with Serpent SER903758

The Serpent SER903758 Brake Pulley Adaptor S989 is developed for the Viper 989 GP chassis to ensure the pulley sits true and the brake linkage behaves predictably. It is a practical part for racers focused on repeatable stopping performance.

How This Adaptor Supports Viper 989 GP Brakes

Engineered to match the Viper 989 GP assembly, the adaptor secures the pulley interface and minimises lateral play. A firm pulley mounting helps maintain steady braking force and improves driver confidence at corner entry.

Best Practices for Installation and Care

Before fitting the Serpent Brake Pulley Adaptor S989, clear any contaminants from the shaft and pulley region. Install the adaptor squarely, tighten fixings to the recommended feel and inspect the assembly after a few runs to ensure lasting performance.

Is this adaptor a direct swap for the original part?

For standard Viper 989 GP configurations the Serpent SER903758 should be a direct replacement. Verify the shape and fixing points if your car has aftermarket modifications.

What are the signs the adaptor needs replacing?

Replace the adaptor if you notice pulley wobble, uneven braking, or visible wear on mating surfaces. Also check for stripped threads or bent components after impacts.

Can I use the adaptor with different pulley sizes?

Using different pulley sizes is possible but make sure the adaptor still aligns the pulley coaxially with the brake shaft. Mismatched pulleys can introduce extra load on the brake system.
