Lazer ZX7.5 Rear Upper Bulkhead LA412 - Chassis Replacement by Kyosho  [KY-LA412]

Upper rear bulkhead for Lazer ZX7.5 chassis

The LA412 rear upper bulk is an RC replacement designed specifically for the Lazer ZX7.5 platform and supplied as Kyosho part LA412. It acts as the upper rear bulkhead that locates suspension arms and supports rear link mounting points on the chassis assembly.

Intended for the Lazer ZX7.5 chassis specification, precise fitment and alignment are important for consistent suspension action. The part replaces the OEM rear upper bulk to recover correct geometry after wear or impact damage has affected handling.

Installation follows typical hobby procedure: remove the rear body fixings and related screws, lift out the old bulkhead, install the LA412 making sure link positions are correct, then refit fasteners with care to avoid thread damage. Reinspect nearby mounts and screws after the first test outing.

Tuning relevance: the rear upper bulk establishes upper link mounting points and contributes to roll-center and camber behavior. A faithful replacement keeps geometry stable, allowing finer link adjustments to produce repeatable tuning outcomes.

Install this component when returning the rear suspension to correct geometry or replacing a damaged bulkhead to maintain dependable chassis balance and tuning precision.
