New CNC-machined black-coated aluminum post links the X4F top deck to the chassis plate.
Part is intended to reduce chassis flex, improving high-speed stability and reducing off-power rotation.
Designed for all track conditions and compatible with X4F (and referenced T4F) configurations.
# What was released Team Xray introduced an aluminum chassis stiffening post for the X4F. The part is CNC-machined and black coated. It connects the top deck directly to the chassis plate to reduce overall chassis flex.
# Why this part exists Chassis flex affects car behavior in several ways: it can reduce stability at speed, increase unwanted rotation when power is cut (off-power rotation), and limit cornering speed. By physically linking the top deck and chassis plate with a rigid post, Team Xray aims to stiffen the center structure and modify those handling traits.
# What the company claims it does According to the product release, the post:
# Technical and compatibility notes
# When and where The release appeared on LiveRC on September 16, 2026, as a Team Xray press release. The manufacturer website was listed as the source for the press release.
# Who will likely use it Racers and hobbyists running the X4F who want a firmer center section and different handling balance will be the primary audience. Drivers experiencing high-speed instability or excessive rotation when rolling off throttle may consider this part to alter those behaviors. It also suits setups across a range of track conditions according to the release.
# Practical considerations for users
# Related parts and context LiveRC also listed related Team Xray product releases around the same time, including new sway bar thickness options for the X4F and a stiff carbon center top deck for other models. A related RC Car Action item described an XRAY aluminum post for T4F & X4F with similar claims, suggesting multiple manufacturers and aftermarket sources are offering comparable center-stiffening solutions.
# Bottom line The new Team Xray aluminum post is a straightforward option part aimed at drivers who want to reduce chassis flex in the X4F to improve high-speed stability and reduce off-power rotation. It's CNC-machined and black coated, designed for track use across conditions. Expect handling changes that require on-track validation and potential additional tuning to get the desired balance.

Team Xray has released new rear anti-roll bars for the ball-bearing roll bar mounting system which is designed to work with the X4 & X4F rear suspension arms.

Hudy has released a steel chassis featuring a revised rear profile that provides additional clearance and compatibility with different rear suspension holder configurations for the XB2.

Team Xray has released a new stiff carbon center top deck designed for GTXE flat chassis configuration, reducing chassis flex for more precise handling & increased corner speed in high-traction conditions.

The Serpent X26 aluminum chassis is around 70 grams lighter than the steel chassis, giving you more room to fine-tune the weight balance of the car, especially in stock racing where bigger and heavier batteries are commonly used.
