XYZ Racing Pro Racing Gravel/Snow Coilovers — Scion XB bB 4WD 2003-2007

The Scion xB bB’s tall, short-wheelbase body and boxy proportions give it a higher centre of gravity than almost anything else on the fitment list, and on loose surfaces that shows up as body roll you feel through the seat before the tyres let go. The Pro Racing Gravel/Snow coilover is built around that problem: a 4WD platform that needs its weight kept in check the moment the surface changes underneath it.

This is XYZ Racing’s specification for rally and rallycross work, not a fast-road remap of a circuit part. Longer travel at both ends and a shock internals package built to survive hours of repeated compression on rutted gravel or packed snow, rather than a handful of smooth laps on tarmac.

What this coilover kit does for your 2003-2007 Scion XB bB 4WD

Fit this kit and the xB bB stops rolling onto its outside dampers the instant you turn onto gravel or snow. The extended front and rear wheel travel gives the suspension more room to absorb a rut or compression event before it runs out of stroke and slams into the bump stop – which matters on a body this tall, where a harsh bottom-out translates straight into unsettling weight transfer. The enlarged suspension oil and nitrogen gas volume means the dampers keep working the same way late into an event as they did at the start, instead of fading as the oil heats up over long-term use. Three external adjustment knobs let you retune compression and rebound between a snow-packed forest stage and a rutted gravel one without pulling the dampers apart.

About the Pro Racing Gravel/Snow coilover

XYZ Racing built the Pro Racing Gravel/Snow line specifically for rally and rallycross use rather than tarmac circuit driving. Both front and rear dampers run noticeably longer travel than the road-biased ranges in the catalogue, giving the suspension a bigger buffer before it runs out of stroke over a jump, rut or compression. Behind that sits an oversized reserve of suspension oil and nitrogen gas: more fluid volume gives the shock more thermal mass to draw on, so oil temperature stays under control across a long stage or a full day’s driving rather than climbing until the damping fades. Each corner carries three external adjustment knobs feeding oil through a deliberately small internal passage – on a big hit you may hear a faint noise as oil is forced through that passage, which is normal and not a fault. It’s a damper built to be driven hard and repeatedly on a loose surface, not babied.

Fitment for the Scion XB bB 4WD (2003-2007)

Built for the SC04 chassis code covering the Scion xB / Toyota bB 4WD, 2003 to 2007. This is the 4WD-specific spec, matched to the driveline and mounting points of the all-wheel-drive variant rather than the FWD version – confirm your V5 or import paperwork shows the 4WD drivetrain before ordering.
