For tuners of vintage XB cars, the XRAY 358034 piston kit supplies 8-hole and 10-hole choices to refine shock behaviour. The 8-hole pistons come in 1.2mm and 1.3mm sizes for stepped damping options, while the 10-hole pistons use 1.1mm holes to maintain consistent flow characteristics.
Produced in a specialist composite, the pistons resist wear while keeping internal friction low. The cone-shaped profile helps manage oil passage and the exact molding process produces round pistons that run true in shock cylinders for repeatable performance lap after lap.
