The XRAY 352225 XB9 Composite Left Caster Block is a key part for drivers wanting crisper steering on the XB9 chassis. This left-side block has a preset 16 deg caster that works with the XB9's 10 deg front kick-up to give a total caster of 26 deg, improving turn-in and on-centre feel for both club racing and practise laps.
The block is clearly marked with the caster value and an L for left, making changes quick to identify. The upper hole keeps the traditional caster position for more steering on low-grip or smooth surfaces, while the lower hole adds stability for high-grip or rough, breaking-in tracks. For a matched pair, use this with the #352215 right-side caster block.
