RC hobbyists seeking steadier cornering will find the XRAY 378096 progressive shock spring a useful upgrade for central shocks. Its progressive C=2.0-2.5 action balances initial compliance with stronger mid-stroke support, helping maintain tyre contact and steering precision.
The progressive rate means the spring starts softer for small inputs and firms up as it compresses, which reduces sudden weight transfer and keeps the chassis stable over undulating surfaces.
When fitted, the XRAY 378096 spring can reduce twitchiness and produce more predictable steering during corner exits and mid-corner corrections, valuable for drivers refining lap times.
