Yokomo YOKD170BK Black Standard Drift Springs 1.1mm Wire 9.5 Coils (Pair)  [YOKD170BK]

Durable standard springs for controlled slides

This Yokomo YOKD170BK spring set targets drivers who fine-tune suspension feel for drifting. The pair of black coil springs uses a 1.1mm wire and 9.5 coils with a regular pitch, which alters spring rate and the shock's travel characteristics when mounted in compatible dampers.

To fit, place the spring onto a matching shock shaft or spring retainer, verify preload and end-of-travel, then compare handling by swapping springs one at a time. Coil pitch and count impact how quickly a damper compresses and returns, so these springs are useful to dial lateral grip and rebound during slides.

Consider these springs part of a broader setup plan that includes shock oil, piston choice, and anti-roll adjustments. Keep changes methodical and document results to confirm whether the 1.1 x 9.5 profile improves your drift balance.
