Peterbilt 587 Front Axle Air Ride Kits

Frequently Asked Questions About Peterbilt 587 Front Axle Air Ride Kits

What does a front axle air ride kit actually replace or upgrade?

A front axle air ride kit converts your Peterbilt 587's front suspension from a traditional leaf spring or mechanical setup to an air-based system. This typically includes air springs (air bags), mounting brackets, height control valves, air lines, and related hardware designed to work together as a system rather than individual replacement parts.

Will this kit fit my specific Peterbilt 587 configuration?

Fitment can vary based on your truck's model year, axle weight rating, and whether it came factory-equipped with air ride or a different suspension type. Before ordering, check the kit's listed specifications against your truck's axle and suspension setup, and compare part numbers with your OEM equipment or your Peterbilt dealer's records to confirm compatibility.

Can I install a front axle air ride kit myself, or should I have a professional do it?

These kits involve suspension, air line routing, and sometimes brake or steering component proximity, so installation requires mechanical experience and proper tools, including a way to safely lift and support the front axle. Many owner-operators with suspension experience complete these installs in a shop setting, but if you're not confident working around air systems and front axle components, having a qualified diesel or truck repair shop handle the install is the safer choice.

How do I know if my current air ride components are worn out versus just needing adjustment?

Common signs of worn air ride components include a front end that sags unevenly, a rougher ride than usual, visible cracking or bulging on air springs, or air leaks you can hear near fittings and bags. If the ride height seems off but you don't see obvious damage, the height control valve may just need adjustment rather than full replacement. Inspecting the air springs, lines, and valve separately can help you pinpoint whether you need a full kit or a single component.

What's the difference between OEM and aftermarket air ride kits for the 587?

OEM kits are built to match Peterbilt's original specifications and are a safe bet if you want a direct match to what came on the truck originally. Aftermarket kits can offer a lower price point and sometimes wider availability, but quality and fitment accuracy can vary by manufacturer. Reading the specific product details and checking reviews for the exact kit you're considering will help you understand what you're getting before you buy.
