XRAY have introduced new aluminium shock towers for the XB4. Machined from high-quality 7075 aluminium, the shock towers come black coated and and laser-engraved with the XRAY logo. Both towers feature updated shock mounting positions with an extra additional shock mounting position for extra-fine tuning. The 3mm thick shock towers sport an ultra-rigid design for unsurpassed strength and long lifespan compared to the carbon fibre stock towers, making the XB4 easier to drive and more predictable.
