Sill Stands 

Browse our range of WRC-specification sill stands from GRP4 Fabrications, engineered for durability and performance. These precision-welded, zinc-plated stands are built to last and come GA1 certified, rated to safely support up to 2,000 kg per set of four. Choose from wide or narrow configurations to suit your storage and paddock setup. Optional interchangeable pins allow teams servicing multiple vehicles to swap between pin sizes to match each car's sill stand mount.

How to Choose the Right Rally Sill Stands

Sill stands are an essential tool for rally teams, providing safe and stable support for your vehicle during servicing or repairs in the paddock or workshop. They securely lift the car at the sill mounting points, evenly distributing the vehicle’s weight and keeping the chassis steady while wheels, suspension, or drivetrain components are removed.

Wide vs Narrow Sill Stands

The choice between wide and narrow sill stands comes down to personal preference and storage. Narrow stands are easier to store in service vehicles and workshops, making them the popular choice for crews where space is at a premium. Wide WRC stands have a base depth of 135mm and offer excellent stability on uneven paddock surfaces.

Both configurations are manufactured by GRP4 Fabrications to WRC specifications, precision-welded and zinc-plated for longevity, GA1 certified, and rated to a Safe Working Load of 2,000 kg per set of four.

Interchangeable Pins

Sill stands are available with or without interchangeable pins. Choosing the correct pin size is essential for stability when the car is on the stands as the wrong size means the stand won't support the vehicle securely.

Fitting Kits

The sill stand fitting kit is a weld-in chassis kit, comprising four 20 mm CDS tubes (150 mm long) and eight reinforcement plates that create permanent sill stand mounting points on your chassis. 

Frequently Asked Questions

What are sill stands used for in rally?

Sill stands support a rally car at its sill mounting points during service halts. Working alongside jacks, they provide stable four-point chassis support while wheel, suspension, and drivetrain work is carried out simultaneously. These stands are GA1 certified and used at all levels of the sport, from club rallying to international competition.

How do I find out what pin size I need?

Use Vernier calipers to measure the diameter of your sill stand mounting tube. This will give you the exact size you need to ensure a secure fit.

Do sill stand mounts need to be fitted to the chassis?

Yes, sill stand mounts need secure mounting points on the chassis to work safely and correctly. Resting the car on sill stands is unsafe as they do not work like axle stands. A weld-in fitting kit creates reinforced chassis mounting points, helping the stands sit properly and support the vehicle evenly during servicing. This is especially important for stability, safety, and repeatable positioning in rally conditions.
