Serpent 401729 Project 4X Touring Car Service Pack  [SER401729]

Must-Have Spares for Project 4X Touring Cars

The Serpent 401729 Starter Pack brings together the most needed spare parts for Project 4X cars, making workshop repairs and setup work straightforward. It is aimed at racers and club drivers who want reliable, ready-to-fit components.

Suspension Arms and Hub Parts

This kit contains both upper and lower wishbones for front and rear, offering robust support across common suspension setups. The wheel hubs are manufactured to precise tolerances to ensure repeatable wheel alignment and consistent performance.

Colour-Coded Springs to Tweak Handling

The pack includes four spring sets marked by colour: yellow C4.9, red C6.3, blue C7.6 and green C9.5. Swapping these springs lets you fine tune body roll, bite and mid corner balance depending on the surface.

Ball Joints for Accurate Geometry

Also supplied are ball joints in two sizes (4.5 and 4.5 short) to help retain correct steering geometry. Choosing the right joint length is important for predictable steering response and tyre life.
