3.0 Linear Shock Spring Yokomo YOKRP-080 Ultra Linear Rate  [YOKRP-080]

Spring function and benefits

The Yokomo YOKRP-080 Linear Ultra Shock Spring 3.0 is made for RC shock assemblies where a linear-rate characteristic is required. The 3.0 designation identifies the specific spring rate and it works well in touring and pan car setups that need repeatable suspension behavior.

Use this spring when you require uniform compression and rebound without the ramp-up of a progressive spring. Keeping the spring rate constant helps you judge changes to damper oil, piston choice, or preload because the spring influence remains predictable.

Fitting is conventional: remove the shock cap and shaft assembly, slide off the existing spring, then place the new spring over the shock shaft and onto the retainer. Clean seating surfaces and verify matching preload and free length between left and right shocks after installation.

Tuning guidance: spring swaps are a key tool to alter chassis balance and cornering roll. A firmer linear spring gives more resistance through the stroke, cutting body roll and increasing mid-corner support. A softer linear spring improves compliance and grip on low-traction surfaces. Pair spring changes with measured preload tweaks to adjust ride height and initial response before changing damper valving.
