Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It supports the front axle, cushions the vehicle from road shocks, and maintains proper ride height and alignment. Over time, front springs can sag, crack, or corrode, causing uneven tire wear and poor handling, so they are replaced when ride height drops or leaves break. The exact load rating and vehicle fitment for this specific part number could not be confirmed, but it belongs to a family of springs commonly used on Kenworth and Peterbilt chassis with front axle ratings around 12,000 lb.
