Camburg 3.25 Race Series TT Rear Hub Kit (6x6.5 / 40sp)

Camburg has built a reputation for making tough, race-winning suspension components, and their 3.25" Race Series TT Rear Hub Kit is a prime example. This is the same setup Camburg uses on their own KINETIK race trucks, designed for serious PreRunners and competition vehicles. It features a larger 6 on 6.5 inch bolt pattern with 40 spline drive plates, built to handle the demands of racing where every second counts.

The design focuses on strength and durability. The hub bodies are machined from 7075-T6 aluminum, a strong yet lightweight material, and are anodized matte black. This aluminum is more expensive but offers increased strength, especially around the wheel stud area. The wheel studs themselves are made from 4340 chromoly, heat-treated, and stress-relieved for maximum toughness, featuring 5/8-18 threads and an 11/16 shoulder for added strength. Camburg also uses a wide bearing spread to enhance longevity and strength, and includes high-quality Timken bearings and races, along with National seals protected by bolt-on stainless retainers.

The drive plates are also crafted from 4340 chromoly, heat-treated, and nickel-plated for corrosion resistance. The kit includes red brake rotor adapters, all necessary hardware, O-rings, and bearing preload spacers. Even small details, like drilled head bolts for safety wiring the brake rotor adapters, show Camburg's commitment to quality and attention to detail. To complete this setup, you will need Camburg's weld-in spindle snouts and their custom spindle nut wrench.
