This is an RC-scale bulkhead center cap set designed for the Works'91 TeamSpec YZ-W91 series chassis. The set serves as direct replacement caps for the bulkhead area and center mount, and it is supplied in a black finish for a consistent appearance with darker chassis components.
The parts are intended to provide accurate seating and alignment for the bulkhead and central mounting points. When maintaining or rebuilding a YZ-W91TS or YZ-W91 chassis, these caps help retain factory alignment tolerances and make repetitive assembly cleaner during routine service.
Installation notes: remove the affected bulkhead or center assembly per 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: while these caps are not a performance part by themselves, they assist in repeatable assembly and reliable mounting, which supports consistent setup and handling during chassis adjustments.
