Trailer Suspension / Rear Slipper Spring Hanger

Rear Slipper Spring Hanger 2" Wide - 3.47" Spring Height to Wear Plate - 6" Tall - 4" Long - (HG-15854-R)

Part Number: HG-15854-R 2" Slipper Spring 3.47" Spring Height

Overview

The HG-15854-R is a rear hanger for slipper spring trailer suspension systems using a 2-inch-wide spring. It is the longer 4-inch version in this style, with a 6-inch overall height and a 3.47-inch spring height to the wear plate. For suspension repairs, matching the actual hanger geometry matters just as much as matching the basic hanger type, especially when ride height, spring tracking, and wear plate position all need to stay in the intended range.

R&P Service Insight

Rear slipper hangers do more than hold the spring in place. Their measurements influence ride height, spring angle, and how the slipper end tracks across the wear area as the suspension cycles.

Height Matters: The 3.47-inch spring height to the wear plate is a critical fitment dimension and should be matched carefully to the original setup.
Width Matters: This hanger is intended for 2-inch-wide slipper spring applications, so narrower spring systems should not be assumed to fit.
Version Matters: This is the 4-inch-long version in this family, not the shorter 3-inch style.

R&P Knowledge Hub

Compatibility: Rear hanger for trailer suspension systems using a 2-inch-wide slipper spring.

Vehicle / System Fit: Best suited for trailer slipper spring suspension repairs where the original hanger dimensions match the dimensional reference, especially the spring width, hanger height, and wear plate height.

Installation Notes: Confirm spring width, hanger height, overall length, inside width, hole size, steel thickness, and weld-on placement before removing the original hanger.

Performance Insight: Matching the wear plate height and hanger geometry helps keep the slipper spring working in the intended arc rather than shifting the suspension into an incorrect angle or ride height.

R&P Repair Insight

Suspension hangers are easy to confuse because many look similar at a glance. The safest way to order a replacement is by matching the actual measurements, especially spring width, height to wear plate, overall height, overall length, material thickness, and hole location.

Check Spring Width: This hanger is built around a 2-inch slipper spring application.
Check Height to Wear Plate: The dimensional reference calls out 3.47 inches for the spring height to the wear plate.
Check Length and Thickness: This is the longer 4-inch version, with the dimensional table showing 0.30-inch material thickness.
