RP-103BRA RP Ultra front spring for YZ-2T/4

The Yokomo RP-103BRA is a front suspension spring built for RC racing, featuring a 1mm increase in free length versus the standard RP series to alter preload and initial travel characteristics.

As a hard-type spring finished in brown, it balances stiffness and compliance to sharpen turn-in and provide more predictable feedback on carpet tracks for buggies and truck classes. Fit this spring when you need stronger front support to limit excessive dive and retain steering precision through mid-corner.

Installation follows standard coil-over practice: swap the current front spring for the RP-103BRA, match initial preload to your baseline, then tweak shock oil or mount position as needed to restore ride height and chassis balance. Make small adjustments to preload and shock valving and test on your familiar carpet layout to understand how the extra 1mm length changes handling.

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 will the front end feel after fitting the RP-103BRA?

Expect a firmer front initial response with crisper turn-in and less nose dive on carpet. You may need to reduce preload slightly or soften shock valving to dial in balance.

Will this spring work with the stock shock pistons and the listed platforms?

Yes, the spring is intended for the listed YZ-2 and YZ-4 platform shock assemblies. Confirm the external free length fits your shock bodies before final assembly.

What are the first tuning steps after installation?

Begin with your usual shock oil and ride height, then adjust preload in small increments. If the car understeers, try softer front pistons or a touch less preload; test iteratively on carpet to find the sweet spot.
