Made for X4 cars, the XRAY 301570 upper clamps give a solid mounting point for caster inserts to improve steering consistency. They attach to the lower bulkheads and the integrated centring lugs help preserve setup accuracy for consistent performance across runs.
Forged from Swiss 7075 T6 aluminium, these clamps combine stiffness and low mass. The parts feature 1mm milled channels for ball-bearing hubs to reduce size and weight while keeping structural strength. A black anodised surface adds protection and a neat finish.
The XRAY 301570 design uses the screws from the bottom of the caster inserts to lock the clamps in position, preventing rotation or loosening during maintenance. Those screws also serve as pivot ball mounts for the upper arms, reducing component count and saving weight.
A practical choice for racers after consistent handling and simplified servicing, the XRAY 301570 upper clamps balance strength and lightness for improved on-track behaviour.
