Quick answer
Haldex and Gunite air brake chambers cross to a premium aftermarket direct replacement the same way any chamber does — by matching type, stroke, service-vs-spring, and mounting rather than the brand. All are built to the standardized DOT 121 spec, so a Haldex or Gunite Type 30/30 clamp-ring spring brake interchanges with an equivalent aftermarket unit. Read the number off the old can or use the VIN; the interchange is decided by the characteristics, not the badge.
Haldex and Gunite chambers are all over trucks and trailers. Here's how to cross one to a premium aftermarket direct replacement without guessing at a brand.
Haldex, Gunite — same standardized part
Haldex is a major air-brake supplier, and Gunite has long been a familiar name on foundation-brake components; you'll read either off chambers on plenty of trucks and trailers. Like every heavy-duty chamber, they're built to the DOT 121 spec — so the number and characteristics on the can, not the brand, are what decide the replacement.
Read the can, match the spec
- Type and stroke — 30/30, long or short — matched exactly.
- Service chamber vs spring brake.
- Clamp-type vs bolt-together and the mounting pattern.
- Pushrod length and clevis so the geometry carries over.
What we stock, and what each one replaces
Every heavy-duty chamber is built to the same DOT 121 standard, so a Haldex or Gunite can is replaced on its type, stroke and mounting — not on its brand name. Read those three things off the old can and match the row:
| Our part | Type | Stroke | Replaces a can marked | Price |
|---|---|---|---|---|
| T3030SHRT | 30/30 spring brake | Short stroke | Type 30/30, short-stroke service side, standard clamp ring | $62.00 |
| NT3030ELS80 | 30/30 spring brake | Long stroke | Type 30/30 marked LS / long-stroke, standard clamp ring | $62.00 |
| T3030DD | 30/30 spring brake | Long stroke | Type 30/30 long-stroke in Bendix or Haldex applications | $73.00 |
Still not sure which one your can is?
Send us the numbers stamped on the old chamber and a photo of the mounting studs. We will tell you which of the three above it is — and if it is not one of them, we will say so rather than sell you a chamber that does not fit. A brake part is not somewhere to guess.
Why it crosses cleanly
Because a Type 30/30 clamp-ring spring brake is a standardized part, a Haldex or Gunite unit crosses to a premium-quality aftermarket direct replacement by matching those points. Our listings show the interchange info on the page, so you order off the number on your old unit. Tag rusted off? The VIN gets the factory spec.
Quality aftermarket at a fair price
A quality aftermarket chamber is built to the same standard and bolts to the same holes as the Haldex or Gunite unit it replaces — you're skipping the badge markup on a commodity, not the braking performance.
