Peterbilt 587 Mud Flaps

Frequently Asked Questions About Peterbilt 587 Mud Flaps

What materials are available for Peterbilt 587 mud flaps, and which is most durable?

Peterbilt 587 mud flaps come in three main materials: rubber, stainless steel, and polymer composite. Heavy-duty rubber flaps (typically 3/8" to 1/2" thick) are the most popular choice, offering excellent durability and flexibility in extreme temperatures. Stainless steel options provide maximum longevity and a polished appearance but are heavier and more expensive. Polymer composite flaps offer a middle ground with good chemical resistance and lighter weight than steel.

Will these mud flaps fit my specific year model Peterbilt 587?

Peterbilt 587 mud flaps are generally compatible with all model years from 2008 to 2015, as the mounting points remained consistent throughout production. However, trucks with aftermarket modifications, custom exhaust systems, or lifted suspensions may require adjustable mounting brackets. Always verify your truck's configuration and measure the mounting area before ordering to ensure proper fitment.

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

Installation typically takes 30-45 minutes per set and requires basic tools: a drill with metal bits (if new holes are needed), socket wrench set, and measuring tape. Most mud flaps come with universal brackets that utilize existing frame holes. The main challenge is ensuring proper clearance from tires during full suspension travel. We recommend having 4-6 inches of clearance from the tire at rest position.

What sizes and styles are available for the Peterbilt 587?

Standard sizes for Peterbilt 587 mud flaps are 24" x 30" for rear and 24" x 24" for front applications. Style options include plain black, anti-spray designs with horizontal grooves, weighted bottom flaps for better stability, and custom logo options. Quarter fender flaps are also available in 16" x 23" for additional coverage behind the fuel tanks.

How do anti-sail brackets work, and do I need them?

Anti-sail brackets prevent mud flaps from flapping excessively at highway speeds, reducing wear and improving appearance. They're highly recommended for drivers who frequently travel at speeds above 65 mph or in windy conditions. These brackets mount between the flap and frame, using adjustable arms to maintain proper tension. While not mandatory, they can extend mud flap life by up to 50% and reduce cabin noise.
