This kit contains rubber O-rings intended for the front push rod assembly on 1/12 on-road competition chassis of the YR-X12 series. The pack includes 6 pcs to replace worn rings and ensure correct push rod seating.
The rings are fitted at the push rod pivot to reduce lateral play and assist in keeping the push rod centred when under load. They are a maintenance and minor tuning component that affects endplay rather than changing suspension geometry.
To install, remove the push rod from the linkage, place the O-ring at the pivot contact point, then reassemble and check for smooth articulation without binding. Inspect periodically and swap out any rings showing flattening, cuts, or other damage.
