The smaller, black, round accumulator fitted to the later Gen 3 trucks that do not have traction control. It does the same job as the large silver cylinder used on the traction-control trucks and it is not the same part. Read the confidence tier on this page carefully: unlike almost everything else in this wave, this number was not read off a catalogue listing for the part itself — it appears in a sentence on the page for the other accumulator, and no second source could be opened to confirm it. That is enough to write the number down and not enough to buy on. On a brake part, take this page to the counter as a starting point, have them look the number up against your chassis number, and have a qualified mechanic confirm which accumulator your truck actually carries before anything is ordered or fitted.
