RP-103BKA Stiffer Front Spring for YZ-2 Family

The Yokomo RP-103BKA front spring increases free length by 1mm over the RP line and uses a hard rate to deliver a firmer yet controlled feel. It is intended as an RC-scale upgrade to raise front-end stiffness and sharpen turn-in response without changing shock bodies or mounts.

Fitment covers YZ-2 and YZ-4 buggies and YZ-2T trucks. The added free length and harder rate help reduce mid-corner roll and sharpen steering on high-grip dirt for buggies and on artificial turf or carpet for trucks. After installation, verify spring preload and consider slightly heavier shock oil or small preload adjustments at the front to regain balance once the front spring rate is increased.

Color: black; fit this spring when you need firmer front response for more precise cornering on high-traction surfaces while keeping an RC-scale setup approach.

How should I adjust shocks after fitting these springs?

Check and set spring preload, then try slightly heavier shock oil or a small reduction in front preload to counter the added stiffness; tune incrementally and test between changes.

What track surfaces suit this hard-rate spring?

This hard spring is best on high-grip dirt for buggies and on artificial turf or carpet when used with YZ-2T trucks, where its firmer rate improves steering precision.
