This cap set is an RC-scale replacement pack made for the Works'91 TeamSpec YZ-W91 series. The black anodized caps are intended as direct replacements for the bulkhead and centre mount areas to keep a tidy, matched appearance on darker chassis parts.
The parts are engineered to provide repeatable seating and alignment at the bulkhead and central mounting positions. When maintaining a YZ-W91TS or YZ-W91 chassis, using these caps helps retain original alignment and simplifies repeated assembly during service intervals.
Installation guidance: remove the affected bulkhead or centre assembly according to your chassis procedure, locate the cap on the mating surface, and fasten with the original screws from the chassis or kit. Verify alignment before final tightening and carry out a functional check of the drivetrain and suspension afterwards.
Setup impact: while these caps do not change power delivery, they support consistent assembly and dependable mounting, which aids in repeatable setup and handling when tuning the chassis.
