Race-Grade Steering Component XRAY 342043

The XRAY 342043 Aluminum Upper Arm Holder Left is intended for the RX8.3 platform to deliver tighter steering and steadier cornering. Constructed from Swiss 7075 T6 aluminum, it stands up to demanding track conditions while helping maintain precise geometry.

Mounting Layout That Supports Fine Tuning

Designed to mate with XRAY's revised aluminum bulkheads, the holder uses one front upper clamp screw and two radio plate screws to enable the Multi-Flex system. Adjusting the radio plate fasteners changes chassis flex and lets racers tune steering sensitivity to suit driving style.

Geometry Shift for Improved Turn Performance

The design lets the upper arms move rearwards, adding caster for increased cornering stability and speed. This tweak helps keep the car predictable in fast corners and improves exit control on mixed-surface tracks.

A reliable upgrade for competitors seeking sharper steering and better cornering, the XRAY 342043 Aluminum Upper Arm Holder Left complements RX8.3 race setups.
Remark :

Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What effect does more caster have on handling?

Increasing caster via rearward arm placement improves straight-line stability and cornering grip, often yielding quicker cornering but sometimes requiring steering trim adjustments.

Is any special tooling required to fit the XRAY 342043?

Standard hex drivers used for RX8.3 assembly are sufficient. Use consistent torque on screws and avoid overtightening the aluminum parts.

Will this part suit high-grip tracks?

Yes, the XRAY 342043 helps you fine-tune steering and chassis flex, which can be beneficial on high-grip surfaces where precise input and stability matter.
