LAZER ZX Series 5.8mm Shock Flange Balls (4pcs) - Kyosho UBW007  [KY-UBW007]

Velvet-coated flange balls for shock pivots

These are Kyosho UBW007 velvet coating 5.8mm shock flange balls supplied as a set of 4 pcs for RC-scale models. The parts are intended as direct spare components for shock end linkages where 5.8mm flange balls are specified. The velvet coating provides a low-friction contact surface intended to help reduce binding at pivot points while preserving the underlying aluminum finish.

Installation is straightforward for users familiar with suspension maintenance: remove the existing flange ball from the shock end or linkage, inspect the mating surface for wear, and fit the new UBW007 flange ball to the shock shaft or rod end. Tighten and verify free movement through the suspension travel before running the vehicle. Standard hand tools such as small hex drivers or pliers used for ball end replacement are typically sufficient.

For tuning purposes, these flange balls serve as wear parts and influence the perceived smoothness of the suspension pivot. Swapping worn or rough flange balls for lightly coated replacements can reduce stiction and improve repeatable movement in low-speed suspension cycles, which helps when dialing in damper and spring behaviour on scale RC tracks.

Supplied as four pcs, the UBW007 flange balls are a practical service part to keep RC suspension pivots moving smoothly and to maintain consistent handling feel during setup and track use.
