R&P Service Insight
A hanger kit should be matched by its actual suspension geometry rather than by a comparable kit number alone. Measure the existing components and record their mounting positions before removing or replacing the suspension hardware.
-
Spring Check: Confirm that the trailer uses 2-inch-wide slipper springs.
-
Equalizer Check: Compare the 12-inch length, 3.78-inch width and mounting-hole locations with the existing equalizers.
-
Hanger Check: Verify each hanger’s width, length and top-to-bolt-center height before welding.
R&P Knowledge Hub
Compatibility: Designed for compatible tandem-axle suspension systems using 2-inch-wide slipper springs and 12-inch equalizers.
System Fit: The front, center and rear hangers create the frame attachment points for the slipper spring suspension. The equalizers mount beneath the center hangers.
Installation Notes: Record the original axle spacing and hanger locations before removing the old components. The replacement hangers must be aligned and welded securely to the trailer frame.
Performance Insight: The equalizers allow movement between the two slipper spring assemblies as the tandem axles travel over changes in the road surface.
Brand & Fitment Note
Selling Brand: R&P Carriages component kit
Application References: BAK-1, APT6SE-GS3, HG-15843-F and HG-15843-R are supplied as general comparison or application references. They do not establish an exact interchange.
What This Means: This listing is for the R&P Carriages 23002 component kit. It is not represented as an OEM-branded BAK-1 or APT6SE-GS3 kit.
Before Ordering: Compare every hanger dimension, bolt height, bolt-hole size, equalizer measurement, spring width and mounting location with the trailer’s existing suspension.
R&P Repair Insight
Suspension geometry affects axle position and spring movement. Do not assume that two kits are interchangeable based only on spring width or equalizer length.
-
Measure Before Removal: Record the center-to-center hanger locations and axle spacing before cutting old hangers from the frame.
-
Inspect the Frame: Check the intended mounting areas and surrounding frame structure before installing new weld-on hangers.
-
Verify Hardware: Confirm that all required nuts, retainers and installation hardware are present before beginning the repair.
