XRAY 358281 Long Progressive Rear Springs Medium-Hard 4 Stripes  [XR-358281]

Rear Suspension Upgrade with XRAY 358281 Long Springs

Targeted at drivers who fine tune suspension, the XRAY 358281 long progressive springs are made for the rear of XB808, XB9, XB8 and XT9 chassis. The design focuses on consistent behaviour across laps and reliable corner hold.

Rising Rate for Controlled Compression

Marked with four stripes for easy recognition, these springs use a progressive curve that begins with medium firmness and becomes firmer as the spring compresses. That rising rate gives good initial bite and increased support as the car dives deeper into a corner.

Factory Matched for Even Performance

Pairs are precisely measured and matched to deliver symmetric damping between left and right. This attention to matching reduces variability and makes incremental tuning more effective at the track.

A straightforward upgrade for anyone chasing repeatable rear performance and crisper cornering response in race conditions.
