WPS Podium Piston Kit for RockShox Vivid Air C1

The WPS Podium Piston Kit for RockShox Vivid Air C1 replaces your shock’s main piston with a high-flow piston from WPS and includes a complete shim kit for custom tuning. The result according to WPS: more grip, more support, and more control. MTB-Raceshop is an official WPS Fitting Centre in Switzerland.

What the kit changes

WPS uses triangular shims from the motorcycle sector: this allows more oil to flow through the depth of the piston, even though it fits the stock piston rod. According to WPS, the stock piston recovers poorly during rapid impacts – this is exactly where the kit comes in.

The kit removes the Vivid's "Touchdown" function, the position-dependent damping throughout the travel. According to WPS, the performance gain from the piston significantly outweighs this loss.

Scope of delivery

• High-flow piston made of aerospace-grade aluminium, CNC-machined and hard-anodized
• Low-friction seal ring
• New clamp plate for the compression shim stack
• Shim kit with all shims for the setups proposed by WPS
• WPS decals

Compatibility

• RockShox: Vivid Air Ultimate and Select+ (version C1)

You can check which version is in your suspension component using the RockShox Trailhead app or trailhead.rockshox.com by entering the serial number.

Options

• Add a service? Select "Fitting + service" and we will perform a full service during installation. If your suspension component is new or freshly serviced, "Fitting only" is sufficient.
• How will your unit reach us? With "Shipping label by email", you will receive a pre-paid Swiss Post label as a PDF via email – simply print it out, attach it to the package, and drop it off at the post office.
• Fixshox top / bottom: Upon request, we can install Fixshox REVO FHIT mounting hardware during the service. You only pay for the bushings (CHF 54.00 each), installation is free. Please select the width of your existing mounting hardware. For Trunnion-mount shocks, this is only possible at the bottom; please verify yourself whether the Fixshox will fit your bike.

How installation works at MTB-Raceshop

1. Book the kit and choose an appointment date. You can select the service, Fixshox, and shipping label as options directly.
2. After placing your order, you will receive an email with a form regarding rider weight, bike, riding style, and terrain. Based on this, we will select your tune.
3. Send us your shock well packed so that it reaches us by the working day before your drop-off date at the latest – with the shipping label if you booked it. Or bring it to Dällikon by arrangement.
4. We will install the kit, tune it, and test the shock on our hand-dyno. It will then be returned to you with a base setup.

Frequently Asked Questions

Can I install the kit myself?

No. WPS offers the Podium Kits through its Fitting Centres, which install and tune the kit. At MTB-Raceshop, we install it in our workshop in Dällikon.

Does a service need to be performed at the same time?

That depends on age and condition. If the suspension component is new or freshly serviced, installation is enough. Otherwise, select "Fitting + service".

What happens to the Touchdown function?

It is removed with the WPS piston. WPS made this decision consciously, as the new piston significantly improves recovery during rapid impacts.

Which tune is installed?

The shim kit contains all shims for the setups proposed by WPS. We will select the one that suits you best based on the information you provide in the form after ordering, regarding rider weight, bike, riding style, and terrain.
