Review: Works well, seems like high quality! - Been using for 3 weeks now - works excellent. It’s not a cheap feeling unit, it feels just like the one that came off the truck, which was an original governor (a bendix unit) Only thing to consider would be I had to transfer some of the hardware from the original governor to this one. So don’t toss your old one before you get this one installed and confirm it works properly. Holds steady pressure around 125psi as the original did, however does fluctuate. Which Is completely normal in my experience Review: Good quality, quick replacement. - The part matched the description and worked well for my truck. The build quality feels solid, and it handled high temperatures as expected. I initially received a faulty unit, but the replacement process was smooth and hassle-free. Overall, I am satisfied with the product and service. ## Features - Precision-engineered D2 Governor for high-temp applications; 5" body length and standard 0.125" NPT threaded ports ensure seamless fitment in heavy-duty air brake systems - Equipped with 3 reservoir and 3 unloader ports, all 0.125" diameter, ideal for maintaining consistent air pressure in high-demand braking systems - Supports pressure regulation in the 100–120 PSI operating range; rugged design helps withstand demanding environments and elevated temperatures - Includes 1 D2 governor unit compatible with numerous OE and aftermarket systems; built for long-lasting performance and reliability in commercial trucks and buses - Replaces over 50 part numbers including Bendix 284358, 109662N, Haldex KN18534, Automann 170.284358, PAI 5658, and more; see below for full list ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IVQQKSQ | | Brand | World American | | Brand Name | World American | | Customer Reviews | 4.5 out of 5 stars 93 Reviews | | Global Trade Identification Number | 00698231599891 | | Included Components | D2 Governor High Temp | | Item Dimensions | 3.2 x 5.8 x 3.9 inches | | Item Highlight | Replaces Bendix 284358/109662N, Haldex KN18534 Automann Port 0.125" Dia 5" Length NPT Thread 3 Reservoir & 3 Unloader Ports Item Highlight Replaces Bendix 284358/109662N, Haldex KN18534 Automann Port 0.125" Dia 5" Length NPT Thread 3 Reservoir & 3 Unloader Ports See more | | Item Type Name | Governor | | Item dimensions L x W x H | 3.2 x 5.8 x 3.9 inches | | Manufacturer | World American | | Material | Metal | | Material Type | Metal | | Model | WA284358 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | WA284358 | | Thread Style | Npt | | Thread Type | Npt | | UPC | 698231599891 | | Unit Count | 1 Count | ## Product Details - **Brand:** World American - **Item dimensions L x W x H:** 3.2 x 5.8 x 3.9 inches - **Material:** Metal - **Thread Type:** Npt - **UPC:** 698231599891 ## Images ![World American WA284358 D2 Governor Air Brake Bendix Style High Temp Replaces Bendix 284358/109662N /275491 Haldex KN18534 Automann Port 0.125" Dia 5" Length NPT Thread 3 Reservoir & 3 Unloader Ports - Image 1](https://m.media-amazon.com/images/I/71EWa0wMkwL.jpg) ![World American WA284358 D2 Governor Air Brake Bendix Style High Temp Replaces Bendix 284358/109662N /275491 Haldex KN18534 Automann Port 0.125" Dia 5" Length NPT Thread 3 Reservoir & 3 Unloader Ports - Image 2](https://m.media-amazon.com/images/I/71aHMMrziKL.jpg) ![World American WA284358 D2 Governor Air Brake Bendix Style High Temp Replaces Bendix 284358/109662N /275491 Haldex KN18534 Automann Port 0.125" Dia 5" Length NPT Thread 3 Reservoir & 3 Unloader Ports - Image 3](https://m.media-amazon.com/images/I/51E3P-G4MCL.jpg) ![World American WA284358 D2 Governor Air Brake Bendix Style High Temp Replaces Bendix 284358/109662N /275491 Haldex KN18534 Automann Port 0.125" Dia 5" Length NPT Thread 3 Reservoir & 3 Unloader Ports - Image 4](https://m.media-amazon.com/images/I/51BxHEkD4sL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well, seems like high quality! *by B***N on May 12, 2025* Been using for 3 weeks now - works excellent.
