This is a left-hand (L/H) S-cam brake camshaft used in heavy-duty truck and trailer air brake systems.
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.
When the brake pedal is applied, the slack adjuster rotates this shaft, causing the S-shaped head to push the brake shoes outward against the drum. Camshafts are replaced when the splines or head wear down, or when the shaft seizes in the spider bracket, which can lead to uneven braking or brake drag. This particular cam is designed for a 16.5-inch brake assembly and measures approximately 17-3/8 inches in length with a 1-1/2 inch journal diameter.
