Upgrade Spring for SLF Short II 1.4 x 20.5L x 4.75T White - Yokomo YOKB7-14475  [YOKB7-14475]

Performance spring for short-stroke suspension

The Yokomo YOKB7-14475 is a white coil spring sized 1.4 x 20.5L x 4.75T intended specifically for SLF Short II shock assemblies on 1/10 scale touring and pan car setups. As a direct replacement spring it maintains a linear characteristic tailored to short-stroke dampers.

Compatibility and fit: this spring is identified for use with SLF Short II components according to the product name, and should be treated as a direct spring replacement where the original spring geometry matches the 1.4 x 20.5L x 4.75T specification. Do not assume compatibility with other shock models unless specified elsewhere by the chassis or shock manufacturer.

Installation notes: remove the shock cap and retainer, slide the worn spring off the shock shaft, and install the YOKB7-14475 in the same orientation as the original. Verify preload and spring seating before reassembling the shock to the hub carrier. Use basic shock service practices such as cleaning the shaft and inspecting seals while swapping springs.

Tuning role: spring choice directly affects compression and rebound balance in short-stroke setups; the 1.4mm wire white spring provides a specific firmness that helps control body roll and ride height in tight, responsive track layouts. Combine spring changes with damper oil and piston tuning to achieve the intended handling rather than relying on spring swaps alone.
