Front Spring Hard +1mm RP-103BKA for YZ-2/2T/4 by Yokomo  [RP-103BKA]

Hard-Rate Front Spring for YZ Buggies and Trucks

Yokomo RP-103BKA is a 1mm-longer, hard-rate front spring that reduces front-end roll and sharpens corner entry. It offers a firmer but controlled feel intended for scale tuning where steering precision is required without changing shock bodies.

This spring fits YZ-2 and YZ-4 buggies and YZ-2T trucks. The extra length and higher rate help cut mid-corner roll and increase steering bite on high-grip dirt for buggies and on artificial turf or carpet for trucks. After fitting, confirm spring preload and consider moving to slightly heavier shock oil or minor preload tweaks at the front to rebalance handling.

Color: black; use this spring when you want a firmer front response for precise cornering on high-traction surfaces while keeping an RC-scale setup philosophy.
