- 2 × King Off-Road piggyback scale shock, 100 mm, with faux reservoir
Compatibility and notes
The manufacturer recommends blue (medium) thread lock on the bottom shock shaft rod end before fitting — otherwise it can work loose. The reservoir is faux: it is a styling element, not a working system.
Who it is for
For modellers building scale crawlers and trail replicas where the detail matters as much as how the model drives. Part of the RC4WD catalogue, so it matches the rest of the brand’s hardware in both look and scale.
