What makes it special

This ST X setup uses threaded shock bodies for precise height adjustment and polyamide spring perches that resist dirt and road grime. The bi-tube damper design, hard-chromed piston rods and a comprehensive sealing package work together to keep performance consistent in British weather. Galvanised bodies with an additional protective finish deliver excellent corrosion resistance, so you can enjoy your chosen drop all year round.

Because the spring rates and damper characteristics are carefully matched, you get a big boost in grip and control without the harshness you might expect from a typical lowering kit. It is a sweet spot between daily usability and performance driving that has made this kit a favourite among our customers.
