Designed for the X4 chassis, the XRAY 301570 aluminium upper clamps provide a rigid anchor for caster inserts to enhance steering repeatability. Fitted to the lower bulkheads, the centring lugs help keep caster angles exact for predictable cornering.
These clamps are CNC machined from Swiss 7075 T6 aluminium to offer a strong yet lightweight solution. They include 1mm milled grooves to suit ball-bearing hubs, trimming bulk while maintaining necessary stiffness. A black anodised finish helps resist wear and keeps them looking sharp.
The XRAY 301570 clamps use screws that come up through the bottom of the caster inserts to lock them in place and avoid loosening during maintenance. Those screws double as pivot ball mounts for the upper arms, reducing part count and overall weight.
For competitive drivers seeking tighter chassis feedback and simpler upkeep, the XRAY 301570 upper clamps are an effective, lightweight upgrade.
