How the LA419 affects rear handling

Kyosho part LA419 is the universal rear swing shaft designed for LAZER ZX7.5 models. The part notation (67/2pcs/ZX7.5) denotes the code and confirms a two-piece pack so you can pair the items with your 1/10 electric on-road rear linkage setup.

As a direct axle replacement, the shaft restores intended pivot spacing and play tolerance in the rear suspension links. Installing a fresh LA419 helps re-establish the original pivot geometry that underpins predictable rear roll and toe response during tuning sessions.

Fit notes: LA419 is specified for LAZER ZX7.5 compatibility, so check the part markings and ensure the pack includes both shafts before you begin setup changes to avoid mismatched sides.

Tuning role: the pivot shaft itself influences roll centre and toe behaviour indirectly by keeping pivot spacing correct. When adjusting rear-end geometry, replace worn shafts and inspect bushings to ensure tuning adjustments deliver consistent results on track.

Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does replacing LA419 change handling?

A new pivot shaft restores correct spacing and reduces unwanted play, which makes roll centre and toe behaviour more predictable and allows finer tuning of rear-end balance.

Is the 2 pcs pack enough for tuning trials?

The 2 pcs pack supplies shafts for both sides of the rear swing, which is normally sufficient for tuning and validation runs on a single chassis.

Can I expect immediate setup changes after swapping shafts?

You may notice cleaner, more consistent rear response once worn pivot play is removed. Always recheck toe and roll settings after replacing the shaft to confirm tuning targets.

Any setup checks post-install to aid tuning?

After installation, perform a suspension sweep and measure toe and roll characteristics during low-speed runs to verify the new shaft produces the expected behaviour before aggressive tuning.
