Xray owners can now run Avid’s machined pistons in their XB4 buggies. The AV1033 pistons are custom machined for XB4 shocks to tune high speed and low speed damping separately with two large 1.5mm (or 1.6mm) holes and two small 1.1mm holes that Avid reft to as their 2+2 piston. Avid’s test drivers found that these pistons help provide the traction and bump handling of running lighter shock oil or larger piston holes, while still maintaining the control of running heavier oil or smaller hole piston when taking on jumps.
