BD7-2014 SLF Normal Shock Shaft for Improved Seal Protection - YOKB7-S5NT Yokomo  [YOKB7-S5NT]

Service shaft with titanium coating for BD7-2014 SLF shocks

This is a replacement shock shaft intended for SLF normal shocks on the BD7-2014 chassis. The shaft uses a carbide titanium surface treatment as described in the product note, which helps minimise abrasion at the shock O-ring and supports steady damper action across service intervals. The pack contains 4 pcs to cover a full car.

To fit the shaft, dismount the shock, open the body, remove the old shaft and internal parts, swap in the new shaft while inspecting seals and piston condition, then rebuild and check for smooth operation and correct oil distribution. This part is designed for maintenance and seal protection rather than being a direct tuning element like springs or pistons.

In terms of setup, the shaft plays a preventative role: by reducing wear where the shaft seals contact the O-ring it helps the damper retain consistent performance between rebuilds, allowing tuning adjustments to focus on oil, pistons, and springs without premature seal failure skewing results.

Use these shafts when servicing BD7-2014 SLF normal shocks to protect the seals and preserve steadier damping between services.
