# Checking Shock Pressure

Shock pressure should be 300psi, air or nitrogen. Nitrogen is preferred due to lower water content, but regular air can and will work in a pinch. It is important to measure with the wheels on the ground.

Keep on top of this! Low shock pressure can lead to inversion of the shock boots during use which will accelerate the failure of the shock.

If you want to use air, you can use any shock pump that is rated for at least 300 psi. The cheapest reliable one we have found is [this one on Amazon](https://www.amazon.com/Pressure-Suspension-Portable-Adjustment-Button/dp/B0BPQHBXQ2). Typically, a larger pump is better, and a larger handle is better too, to save your hands. The chuck on the linked pump works fine. With other pumps, we recommend this [no-loss chuck](https://powertank.com/products/pt-shock-chuck).

When you check shock pressure with your pump, it will typically lose approximately 100psi just from filling the hose and pressure gauge, as the shocks have very low air volume. Refill back to 300psi after checking. A future factory upgrade will include enlarged air reservoirs, which will reduce this effect and reduce maintenance intervals for the shock.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
