The Factory Pro O-XCP013 brace pack provides a simple reinforcement option for the Xray X4 front upper deck. Two thickness choices let racers alter front stiffness in measured steps so you can dial in handling without altering the main chassis plate.
The set contains one 1mm brace and one 2mm brace, each supplied as a single piece to allow quick test swaps during setup. Thinner material preserves more front flex while the thicker plate raises front-end rigidity. Braces are produced to align with the X4 front upper deck mounting pattern so they can be fitted or stacked with the existing layout.
Installation tip: fit the braces using the stock front upper deck locations and original hardware where possible. Confirm hole alignment and part clearance before final tightening, and test changes on your usual surface to assess balance and steering changes.
