Peterbilt 359 Hub Adapters

Frequently Asked Questions About Peterbilt 359 Hub Adapters

Will these hub adapters fit my specific year Peterbilt 359?

Our hub adapters are designed to fit Peterbilt 359 models from 1967-1987 with standard 10-lug hubs. However, some late-model 359s (1985-1987) may have different hub configurations depending on axle specifications. We recommend checking your current hub bolt pattern and pilot diameter before ordering. If you're unsure, contact us with your OEM or current hub measurements and we'll help verify compatibility.

What's the difference between aluminum and steel hub adapters, and which should I choose?

Aluminum adapters are lighter (typically 15-20 lbs per adapter) and resist corrosion better, making them ideal for show trucks or drivers concerned about weight. Steel adapters are heavier (25-30 lbs each) but offer superior strength and are more budget-friendly. For heavy-haul applications or trucks that see rough conditions, steel is recommended. Both types use the same grade 8 mounting hardware and provide equal spacing accuracy.

How difficult is the installation, and what tools do I need?

Installation typically takes 2-3 hours per axle for someone with basic mechanical skills. You'll need a torque wrench capable of 450-500 ft-lbs, a heavy-duty impact gun, jack stands rated for commercial trucks, and a dial indicator to check runout. The most challenging part is achieving proper torque on the inner mounting bolts. Many customers report success doing it themselves, but first-timers often prefer professional installation to ensure proper alignment and torque specifications.

What wheel options do these adapters open up for my 359?

These adapters convert your hub-piloted setup to accept stud-piloted wheels, significantly expanding your wheel choices. You can run classic Alcoa aluminum wheels, chrome steel wheels, or modern alloy designs previously incompatible with your truck. The adapters accommodate both 24.5" and 22.5" wheel sizes. Popular conversions include switching from plain steel wheels to polished aluminum or adding wider wheels for a more aggressive stance.

Do hub adapters affect my truck's handling or cause vibration issues?

Quality hub adapters, when properly installed, should not cause vibration or handling problems. The key is ensuring less than 0.005" runout during installation and using a dial indicator to verify. Some customers initially experience slight vibration due to improper installation or not re-torquing after 50-100 miles. Our adapters are precision-machined to maintain factory wheel offset and track width. If you experience any vibration after installation, it's typically resolved by checking torque specs and wheel balance.
