Frequently Asked Questions About Kenworth W900A Fuel Tank Brackets & Straps

Will these fuel tank brackets fit my specific year W900A model?

Our fuel tank brackets and straps are designed to fit Kenworth W900A models from 1961 to 1985. However, there were minor variations in tank mounting configurations throughout these years. We recommend measuring your existing bracket mounting points or contacting us with your VIN to ensure proper fitment. Most brackets are universal within the W900A range, but some 1961-1965 models may require specific early-style mounting hardware.

What's the difference between aluminum and steel fuel tank brackets?

Steel brackets are the OEM standard, offering maximum strength and typically lasting 15-20 years with proper maintenance. They require periodic inspection for rust and repainting. Aluminum brackets weigh about 40% less, won't rust, and are ideal for weight-conscious applications, but they cost approximately 30-50% more. Both types use the same mounting points and are equally safe when properly installed. Choose steel for budget-friendly durability or aluminum for weight savings and corrosion resistance.

Can I install these brackets myself, or do I need special tools?

Installation typically requires basic hand tools including socket wrenches (usually 3/4" and 7/8"), a torque wrench, and jack stands or a lift to safely support the fuel tank. The job takes 2-4 hours per side for experienced mechanics. Critical steps include properly supporting the tank weight before removing old brackets and torquing mounting bolts to 75-85 ft-lbs. While DIY installation is possible, we recommend professional installation if you're uncomfortable working with heavy fuel tanks or lack proper lifting equipment.

How do I know when my fuel tank straps need replacement?

Inspect your straps every 6 months for these warning signs: visible cracks or tears in the rubber coating, exposed or fraying steel cables, excessive stretching (strap hangs more than 2 inches lower than normal), rust on metal components, or loose mounting points. Replace straps immediately if you notice any fuel tank movement while driving, hear metallic clanking sounds, or see wear marks on the tank itself. Most straps should be replaced every 8-10 years as preventive maintenance.

What's included in a complete bracket and strap kit?

A complete kit typically includes two L-shaped mounting brackets (driver and passenger side), two heavy-duty rubber-coated steel straps, all necessary Grade 8 mounting bolts and lock washers, and rubber isolator pads to prevent metal-to-metal contact. Some kits also include new strap adjusting bolts and anti-vibration washers. Always verify kit contents before ordering, as some applications may require additional crossmember brackets or special offset mounting hardware sold separately.
