This RC-scale centre and bulkhead cap set is intended for the Works'91 TeamSpec YZ-W91 series chassis. Supplied in black anodize, the caps act as direct replacements for the central mount and bulkhead areas to maintain a uniform appearance with darker chassis components.
The parts ensure consistent seating and alignment for central mounting points. During maintenance or rebuilds of a YZ-W91TS or YZ-W91 chassis, they help preserve factory alignment standards and simplify repeat assembly tasks.
Fitting instructions: remove the relevant bulkhead or centre assembly following your chassis service routine, locate the cap on the mating surface and secure using the original fasteners where applicable. Confirm correct alignment before final tightening and perform a functional check of the drivetrain and suspension after reassembly.
Effect on setup: the caps are not a performance upgrade on their own, but they support repeatable assembly and secure mounting which contributes to stable handling and predictable setup changes.
