Upper Bulkhead Brace Set for XRAY X4 (1mm)

Introducing our 1mm Upper Bulkhead Brace Set for the XRAY X4!

With the upper bulkheads being a weaker point of the X4, we decided to give them some rigidity, to help them stay straight in a crash and keep you on the track and gunning for PB's!

Whether you have the original, or beefier upgraded bulkheads, these are a great way to give them the support they need, without effecting the flex or handling of your chassis. They're also only 0.3g each in weight, so have a negligible effect on your CG.

The 1mm thick carbon braces are directional, and screw in underneath the upper bulkhead. This is great because they clamp down directly under the upper bulkhead, meaning more contact to the bulkhead, keeping them as stiff as possible. The brace is then held in place with normal button head screws which you already have installed. You may need to use slightly longer screws depending on what shims you use on the upper arms.

These braces can work underneath the bulkhead, with both low and high diffs, with standard driveshaft blades and ball bearing driveshafts

If you're using ball bearing driveshafts or bladed driveshafts with only low diffs, then we have an EVEN stronger option for you! Check out our Heavy Duty Bulkhead Brace Set HERE!
