This RC-scale bulkhead center cap set is designed for the Works'91 TeamSpec YZ-W91 series chassis. The kit provides direct replacement caps for the bulkhead area and central mount and is supplied in a black anodized finish to match darker chassis components.
The components are intended to secure accurate seating and alignment for the bulkhead and central mounting points. When servicing or rebuilding a YZ-W91TS or YZ-W91 chassis, these caps help preserve factory alignment tolerances and make repeatable assembly cleaner during routine maintenance.
Installation notes: remove the affected bulkhead or center assembly following your chassis service routine, fit the cap to the mating surface, and fasten using the original fasteners from the chassis or kit. Confirm alignment before final tightening and perform a functional check of drivetrain and suspension after reassembly.
Tuning role: these caps are not a power-imparting upgrade, but they improve repeatable assembly and secure mounting, which supports consistent setup and predictable handling during chassis adjustments.
