Upgrade your X4 suspension with the XRAY 308027 XLP Composite 4-Hole Pistons to get crisper damping and dependable durability. The composite construction keeps weight down while providing consistent piston action lap after lap.
The 4-hole design offers two hole size options, 1.1mm and 1.2mm, so you can tune how quickly oil passes the piston. That lets you tailor damping to smoother indoor tracks or more abrasive layouts for improved cornering feel.
Made to match the XRAY X4 series shock geometry, these pistons fit without modification and slot into routine shock rebuilds. The changeover is straightforward for club racers who want fast, reliable upgrades.
