Fine-tune Rear Suspension with XRAY 358274 Progressive Springs

The XRAY 358274 Progressive Rear Spring Set is built for hobbyists who want to dial in rear-end feel and traction. Made for the XB808 and XB9, the springs start softer at C=0.5 and ramp up to C=0.6, giving a controlled transition from initial compliance to firmer support under heavy loads. That progressive profile helps balance turn-in and stability across varied track surfaces.

Notable Benefits of the Progressive Spring Set

  • Progressive Compression: Begins at C=0.5 and rises to C=0.6 to smooth small bumps while resisting bottoming on big hits.
  • Pearl-Grey Finish: Easy to spot when sorting parts and adds a neat, understated look to the rear end.
  • Compatibility: Specifically made to fit XRAY XB808 and XB9 chassis for a consistent installation and predictable behaviour.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do these progressive springs change handling compared to linear springs?

Progressive springs give a softer initial travel for better traction on small bumps and a firmer end stroke for support during big compressions, so you get more predictable corner entry and less bottoming.

Will I need different shocks when fitting these springs?

In most cases your standard XB808 or XB9 shocks will work. Check spring length and preload, and adjust damping to match the progressive rate for best results.

What surfaces suit these springs best?

They are versatile for a mix of carpet, clay and hard-packed dirt where you need initial compliance and mid-stroke support. Tweak setup to suit specific track conditions.
