What This Kit Covers
PN3C006430 is a mud flap hanger and flap kit built around a 28" arm with 1-1/8" bolt spacing. The arm is 430 stainless, chosen because it holds up to road salt, brine spray, and the constant vibration a flap hanger sees behind the drives. It ships as a pair, so both sides get replaced at the same time.
The pivot is spring-loaded. When the flap catches a curb, a dock approach, or a snow bank, the spring lets the arm swing back and return instead of bending the arm or tearing the flap off the bolts. That same spring tension is what keeps the flap hanging straight instead of drooping into the tire at highway speed.
This is an aftermarket direct replacement, not a factory part. It is designed to bolt to common Freightliner and Peterbilt mounting locations without cutting or welding. Fit still needs to be confirmed against your truck — measure the old hanger and check your bolt spacing before you order.
Why These Numbers Cross
PN3C006430 is our stocking number. The cross-references listed for it are 006-430 and 02224LLR. Those numbers appear on hangers with the same governing dimensions: 28" arm length, 1-1/8" mounting bolt spacing, and a spring-loaded pivot at the frame end. Same form, same function, same mounting footprint.
Mud flap hangers cross cleanly because the part is defined by geometry, not by electronics or calibration. If the arm length matches, the bolt spacing matches, and the spring pivot sits in the same plane, the flap hangs where it did before. That is why one number can supersede several catalog listings across different suppliers.
Those cross-reference numbers are listed for identification only. PartStop LLC is not affiliated with, endorsed by, or authorized by any OEM. Use the numbers to confirm you are looking at the right style of hanger, then verify against the number stamped or tagged on the part you are pulling off, or by VIN.
How These Fail And What To Check
Two failure modes dominate. First, the spring loses tension or seizes with packed road grime, so the arm stops rebounding and the flap sits low enough to catch the tire or the ground. Second, the arm takes a hard hit and stays bent, which throws the flap out of plane and puts spray back onto the trailer and following traffic.
Before ordering, measure the existing arm from the frame mount to the flap end and confirm 28". Check bolt spacing at the mount — 1-1/8" is what this kit is built to. Look at the frame holes too; if they are elongated from years of flap load, plan on new hardware and possibly a backing plate.
Replace hangers in pairs. A fresh spring on one side and a tired one on the other gives you two different flap heights, and DOT inspectors notice a flap that hangs wrong or drags. Torque the mount hardware evenly and cycle the arm by hand before the truck leaves the shop.

Frequently asked questions
Does PN3C006430 come with the flaps or just the hangers?
The kit includes hangers and flaps, and it is sold as a pair so both sides are covered. That saves a second order when you find the opposite-side spring is just as tired as the one that failed. Verify the flap size you need matches your current setup before ordering.
Will this fit my Freightliner or Peterbilt without modification?
It is designed to bolt on at common Freightliner and Peterbilt mounting points with no welding or fabrication. That said, we cannot promise fitment from a model name alone. Confirm by VIN, or measure the 28" arm length and 1-1/8" bolt spacing against the hanger you are removing.
Is 02224LLR the same part as 006-430?
Both are listed as cross-references for PN3C006430 because they share the same arm length, bolt spacing, and spring-loaded pivot design. Cross-reference is a starting point for identification, not a fitment guarantee. Check the number on the old hanger and match the physical dimensions before you commit.
