Long cylinder option for R12 rear dampers

This long rear shock cylinder is an RC damper part made for R12 rear shock assemblies. It supplies a longer cylinder body that changes travel range and increases internal oil capacity relative to standard cylinders, recommended for suspension tuning or when replacing aged damper components.

Use is restricted to R12-configured rear dampers as indicated by the model designation. When installing, confirm piston and seal compatibility and check shaft clearances; ensure O-rings are seated correctly to prevent leakage. Match shock oil and piston choices to achieve the desired damping performance.

Tuning impact: the additional oil capacity available with the longer cylinder can alter rebound and compression feel, affecting rear-end balance and chassis attitude. Tweak settings stepwise and keep notes so you can reproduce successful setups.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 does this change suspension setup strategy?

The longer cylinder raises oil capacity and travel, which lets you use different piston and oil combinations to tune rear roll and rebound; adjust settings gradually to find the right balance.

Are special pistons required for the longer body?

In most cases existing pistons will fit, but verify their position and travel range inside the longer cylinder. If pistons sit incorrectly you may need alternate pistons or spacers to achieve the intended damping curve.

Will changing to this cylinder require spring changes?

Spring rates may not need to change immediately, but the altered damping characteristics can reveal different chassis behavior; evaluate spring choice after tuning damping settings.
