RP Ultra front spring for YZ-2T/4

The RP-103BRA is a front suspension spring designed for RC racing use, developed with a 1mm increase in free length compared with the conventional RP series to alter preload and initial travel characteristics.

Constructed as a hard-type spring in brown, it delivers a balance of suppleness and firmness intended to sharpen turn-in and offer more predictable feedback on carpeted surfaces for racing buggies and truck classes. Use it when you need firmer front support to resist excessive dive and to maintain steering precision through mid-corner.

Installation is typical for coil-over setups: replace the existing front spring with the RP-103BRA, set initial preload to match your current baseline, and adjust shock oil or mounting position as required to restore ride height and balance. Small changes to preload or shock valving will reveal how the extra 1mm length affects handling, so tune incrementally and test on your usual carpet layout.

Remark :

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.

What handling change should I expect after fitting this spring?

Expect firmer front response with improved turn-in and reduced dive, particularly on carpet; tune preload and shock settings to balance the chassis.

Is this spring compatible with stock shock pistons and platforms listed?

Yes, the spring is intended for the listed YZ-2 and YZ-4 platform shocks; confirm external spring length fits your shock bodies before final installation.

How should I tune other suspension parts after installing RP-103BRA?

Start with original shock oil and ride height, then adjust shock piston or oil weight to control rebound; small steps help find the correct balance for carpet conditions.
