A direct-fit replacement slipper spring for Lippert 2,000 lb RV trailer axles. Built from heavy-duty steel with a black finish, this 4-leaf unit absorbs road shock, stabilizes axle alignment, and is designed for a straightforward bolt-on installation in approximately 2 hours.
Leaf springs are one of the hardest-working and most overlooked components on any travel trailer or fifth wheel. The Lippert 136527 is a slipper-style spring, meaning one end has a fixed eye loop that mounts to the hanger, while the opposite end slides freely in a slipper bracket -- allowing the spring pack to flex and elongate under load without binding. This design is standard on the vast majority of Lippert-equipped single and tandem axle trailers rated at 2,000 lbs per axle.
When your existing leaves crack, sag, or lose arch, handling suffers and your axle can shift under braking. Replacing worn springs with a factory-spec Lippert unit restores proper ride height, axle centering, and load distribution -- especially important if you carry max payload or frequently travel rough back roads.
Multiple stacked leaves work together to distribute load evenly and progressively absorb bumps, reducing stress on any single leaf.
The free-sliding slipper end prevents binding during suspension travel, extending spring and bracket life compared to double-eye designs.
Black-painted steel construction built to handle repeated flex cycles across thousands of road miles in varying weather conditions.
Rated at 2,000 lbs per axle -- matches the original spec on Lippert 2,000 lb straight and drop axle assemblies common on single and tandem setups.
Before ordering, confirm your axle's spring style. Slipper springs have one eye (fixed end) and one flat sliding end. Double-eye springs have a loop at both ends. The 136527 is a slipper style only and will not work with double-eye hangers. Check your existing spring or the Lippert axle tag to confirm.
The slipper spring assembly consists of a main leaf with an eye at the front and a set of progressively shorter leaves nested underneath. The rear (slipper) end rests in a cradle bracket mounted to the axle perch -- it slides forward and backward as the spring compresses and rebounds. This simple, low-maintenance design has been standard on light trailer axles for decades because it requires no bushings at the slipper end, reducing maintenance points.
