Meritor chambers ride under a lot of trucks and trailers. Here's how to cross one to a premium aftermarket direct replacement by the number on the can, not the badge.
Meritor is a foundation-brake mainstay
Meritor is one of the biggest names in heavy-duty drivetrain and brake components, and their air brake chambers are common across the fleet. As with every chamber, they're built to the DOT 121 standard — so a Meritor Type 30/30 crosses on its type, stroke and mounting, and the badge isn't what you're matching.
Read these off the old unit
- Type and stroke — matched exactly (30/30, long vs short).
- Service chamber vs spring brake.
- Clamp-type vs bolt-together and the mounting studs.
- Pushrod length and clevis for unchanged geometry.
Crossing it cleanly
Match those characteristics and a Meritor chamber crosses to a premium-quality aftermarket direct replacement. Our listings show the interchange info on the page — order off the number on your old Meritor unit. No tag left? The VIN gets the factory spec.
Aftermarket that measures up
A quality aftermarket chamber is built to the same standard and bolts in the same as the Meritor unit — same type, stroke and mounting, minus the dealer markup on a commodity part.
