XRAY T4 Rear Topdeck 2.0mm Chassis Plate - Arrowmax AM-920014  [AM-920014]

Rear topdeck replacement for XRAY T4 FWD

The Arrowmax AM-920014 2.0mm rear topdeck serves as an RC-scale replacement plate for XRAY T4 front-wheel-drive chassis and is aimed at changing rear rigidity and balance. It is intended as a tuning part to influence how the rear end behaves during corner entry and traction change periods on track.

Compatibility is limited to XRAY T4 FWD formats named in the title and requires standard T4 chassis mounting points and common hex fasteners. Installation is straightforward for experienced modelmakers: remove the existing topdeck, align the 2.0mm rear plate with the posts, and tighten evenly to avoid preload or distortion.

This plate increases rear torsional stiffness compared with the stock item, typically sharpening turn-in and altering mid-corner traction response without changing suspension geometry. Couple this modification with anti-roll bar and damper adjustments to dial in handling, and routinely inspect screw torque and contact surfaces to keep behaviour predictable.
