This pack contains O-rings made for the front push rod assembly used on 1/12 on-road competition chassis YR-X12 series. The set includes 6 pcs of rubber O-rings supplied as direct replacements to correct wear and restore proper push rod seating.
The rings sit at the push rod pivot to limit lateral play and help keep the push rod centred under load. They are a small maintenance and tuning item that changes endplay at the joint rather than altering suspension geometry.
Installation is simple: remove the push rod from its linkage, fit the O-ring at the pivot contact, then reassemble and confirm smooth movement without binding. Check O-rings regularly for flattening or cuts and swap them out when worn.
