LAZER ZX7.5 Rear Swing Shaft Upgrade for 1/10 On-Road - Kyosho LA419  [KY-LA419]

Replacement rear swing shaft for LAZER ZX7.5

This replacement swing shaft is supplied as Kyosho part LA419 for use with LAZER ZX7.5 models. The package designation (67/2pcs/ZX7.5) identifies the part code and the pack quantity so you can match it to existing rear swing components on your 1/10 electric on-road chassis.

Functionally the shaft acts as a direct rear swing axle replacement, restoring geometry and play tolerance in the rear suspension link assembly. Fit it where the original shaft shows wear or play, or during a rebuild when consistent pivot alignment is required for stable handling.

Fit notes: LA419 is intended for LAZER ZX7.5 compatibility as stated, so confirm the part markings and the two-piece pack before installation to ensure you have matching items for both sides of the rear linkage.

Installation and tuning role: the component replaces the pivot shaft in the rear swing assembly and will influence rear roll centre and toe behaviour indirectly by maintaining correct pivot spacing. When servicing the rear swing, check mating bushings and track for wear and renew components as needed to retain the intended suspension geometry.
