Keep that long-nose Classic stopping crisp and straight. Our shelf is loaded with direct-fit brake chambers, diaphragms, slack adjusters, and the small bits that tie it all together. Swap them in fast, roll out safer.

Why Choose Our Heavy Duty Truck Brake Chambers?

- Rock-solid build. Thick steel housings shrug off gravel, salt, and brutal heat. - Air-tight seals. Premium diaphragms lock in pressure, so the pedal feels firm every time. - DOT-legal stroke. Long-stroke or standard cans keep push-rod travel in spec and citations off your record. - Plug-and-play hardware. Clevis pins, yokes, boots—all cut to factory length for a no-guess install. - Tested for big loads. Every part meets or beats OEM burst ratings, so you haul heavy without worry.

Maintain Your Semi Truck's Stopping Power

Hauling payloads coast-to-coast? These heavy-duty air brake parts stand up to endless grades and stop-and-go docks. Running local? Quick pedal response keeps you nimble in traffic. Either way, fewer roadside repairs mean more miles turned and money earned.

Fully Upgrade Your Freightliner Classic

While the wheels are off, tighten new semi truck torque rods and U-bolts, and durable dampeners (shocks). You can level the ride with some BESTfit Freightliner air springs and height valves. A stable axle protects your new brake hardware and keeps your Freightliner Classic tracking true.
