Yokomo YOKRP-083BK - Ultra Off-Road Front Spring (Black) Racing Performer  [YOKRP-083BK]

Front spring for off-road tuning

This is an RC-scale front suspension spring intended for off-road use, supplied under the Yokomo YOKRP-083BK designation and finished in black as indicated by the product name. The component is offered as a direct replacement spring for front shock assemblies and is focused on providing a straightforward way to alter ride characteristics without changing shock bodies or pistons.

Installation is typical for coil-type shock springs: remove the shock cap or spring retainer, slide the original spring off the shock shaft, and fit the replacement spring making sure the spring seat and retainer are correctly positioned. Use appropriate shock assembly tools and observe standard RC workshop safety practices when handling compressed springs and disassembled shocks. This article assumes familiarity with basic shock disassembly on scale RC off-road models.

In tuning terms, a front spring primarily affects ride height, initial compliance, and how the front end responds to weight transfer. When paired with changes to shock preload, damping, or anti-roll components, swapping springs is a practical method to dial in understeer/oversteer balance and front grip on loose or mixed surfaces. Test changes incrementally and document setups so you can revert or compare results trackside.

For maintenance, inspect springs for straightness and any coating wear that could lead to binding on the shock shaft or spring seat. Clean mounting surfaces and check that retainers and collars are fully engaged after reassembly. Because this is a scale RC part, confirm fitment with your existing shock length and spring seat configuration before final installation.
