Peterbilt 387 Front Axle Air Ride Kits

Frequently Asked Questions About Peterbilt 387 Front Axle Air Ride Kits

What does a front axle air ride kit actually do?

A front axle air ride kit replaces or supplements the traditional leaf spring suspension setup with an air-based system designed to smooth out the ride quality of your Peterbilt 387. These kits typically use air bags, brackets, and related hardware to help absorb road vibration and reduce the shock transferred to the cab and frame, which can improve driver comfort on long hauls.

Will this kit fit my specific Peterbilt 387 configuration?

Fitment can vary based on your truck's model year, axle capacity, and original suspension setup, since Peterbilt 387s were built with different front-end configurations over their production run. Before ordering, check the listed specifications on each product page and compare them to your truck's axle rating and existing suspension components. If you're unsure, having your VIN and axle weight rating on hand will help when contacting our support team.

What's involved in installing a front axle air ride kit?

Installation generally involves removing the existing leaf spring components and mounting the new air ride brackets, air bags, and related hardware in their place. This is a job that typically requires a lift, proper tools, and a good working knowledge of front suspension systems. Most shops recommend having this done by a qualified technician or truck suspension specialist, since incorrect installation can affect ride height, alignment, and steering geometry.

What materials and components are included in these kits?

Most kits include the core air ride components such as air bags, mounting brackets, and hardware, though exact contents vary by manufacturer and specific kit. Brackets are commonly made from steel for durability under constant road stress. Always check the product listing for a full breakdown of included parts, since some kits may require additional components like air lines, height control valves, or fittings sold separately.

Will switching to an air ride front suspension affect my truck's ride height or alignment?

Yes, changing your front suspension type can affect ride height and may require realignment once the kit is installed. It's a good idea to plan for a post-installation alignment check to make sure your steering geometry and tire wear stay within normal specs. If you notice uneven handling or tire wear after installation, have the front end inspected by a suspension professional.
