The XRAY 309862 stainless steel weight gives T4 pilots a straightforward way to tweak handling. At 35 grams it mounts under narrow battery packs to reduce roll and improve overall chassis poise for the XRAY T4 series.
Keeping mass close to the track surface helps stabilise the car and smooth out transitions between corners. The 135x33x1mm dimensions match common 1/10 on-road arrangements and fit where narrow packs are used.
Installation of the XRAY 309862 requires minimal effort and no bespoke tools. It works with the T4 2020 Specs (300026) (300027) so racers can refine balance without swapping major components.
