A worn or cracked leaf spring doesn't just make your ride rough -- it puts your axle alignment and tire wear at risk on every trip. The Lippert 176326 is a direct-replacement 5-leaf slipper spring built for 5,000 lb trailer axles. At 30 inches from the front eyelet to the slipper end, it matches the OEM geometry on a wide range of travel trailers and fifth wheels equipped with Lippert and Dexter-style axle hangers. Heavy-duty black steel construction and a 4 lb assembly weight make this a straightforward weekend replacement job.
Leaf springs are the workhorses of your trailer's suspension. Every pothole, railroad crossing, and gravel road transfers force through these leaves -- and over time that repeated flex causes fatigue, cracks, or complete failure. The Lippert 176326 restores OEM-equivalent spring rate and ride quality without custom fabrication or modifications to your existing axle hanger hardware.
The slipper design -- where the rear of the spring slides freely in a slotted bracket rather than pinning at both ends -- allows the spring pack to lengthen under load. This is the standard configuration on most single- and tandem-axle RV trailers in the 5,000 lb per-axle range. If your current spring has a fixed rear eye, this part is not a drop-in match; check your existing hardware before ordering.
Five progressive steel leaves deliver a firm but compliant spring rate calibrated for 5,000 lb axle loads. More leaves than lighter-duty 3- or 4-leaf springs for improved load distribution.
Measured from the center of the front mounting eyelet to the slipper tab end. Matches the hanger spacing on most Lippert and compatible trailer frames in this weight class.
Standard 2.5-inch width aligns with the most common slipper brackets and U-bolt saddle assemblies used on 5,000 lb RV axles. No bracket modifications required on matching setups.
Hot-formed steel leaves with a black finish. At 4 lbs for the complete assembly, it handles road load without adding unnecessary unsprung weight to your axle.
Before ordering, confirm your rear spring mount style:
Look under your trailer at the rear spring mount. If you see the spring end sitting in a curved or flat slide channel rather than through a bolt, you have a slipper mount and this spring is the correct style.
