This pack supplies O-rings intended for the front push rod assembly of 1/12 on-road competition chassis in the YR-X12 family. The set contains six rubber O-rings to replace worn items and return the push rod to correct seating height.
The O-rings locate around the push rod pivot, cutting down lateral play and helping the rod remain centred under load. They change the feel by limiting endplay at the joint but do not alter suspension geometry.
Fitment is quick: remove the push rod from the linkage, position the O-ring at the pivot contact point, then reassemble and check for free movement without binding. Replace if you notice flattening, tears, or excessive wear.
