If you're serious about off-roading or racing, you know that the right rear hub can make all the difference. That’s where our Camburg 3.25 rear hubs come into play. These aren’t just any hubs; they’re the same ones we trust on our KINETIK 7200/6100/TT builds. Designed specifically for race trucks and hardcore prerunners, they’re built tough for those who push their machines to the limit.

First off, let’s talk about the build quality. We CNC machine these hubs from 7075-T6 aluminum, which is some of the best stuff you can get. It’s not just for show; this material is lightweight yet incredibly strong. The matte black type II anodizing gives them a sleek finish while adding a layer of protection against the elements. Plus, we’ve beefed up the hub body with larger 8” round material around the wheel stud area, so you can trust they’ll hold up under pressure.

Now, onto the nitty-gritty: these hubs feature a 6 on 6.5” racing bolt pattern, which is perfect for serious setups. They come with either 36 or 40 spline drive plates, giving you options based on your specific needs. The wide bearing spread enhances strength and longevity, which means fewer worries when you’re out on the course.

We don’t skimp on the details either. Our wheel studs are made from 4340 chromoly and are heat-treated, stress-relieved, and black-oxide coated for durability. They’re 5/8-18 threads with an 11/16 shoulder, ensuring they can take a beating without failing. And those tapered hub-centric center caps? They make it a breeze to get your wheels on quickly, which is crucial when every second counts.

We also include high-quality Timken bearings and races, along with National seals that come with stainless retainers for extra protection. The drive plates are also made from 4340 chromoly and feature heat treatment and nickel plating for corrosion resistance. We even provide red brake rotor adapters with all the necessary hardware and bearing preload spacers. Just a heads up, those preload spacers will need some final machining during assembly, but that’s just part of the process.

To wrap up this setup, you’ll need our weld-in spindle snouts and a custom spindle nut wrench. Just make sure your wheels have a 4.25” center-bore and are machined for 5/8” wheel studs, and you’ll be good to go.
