Lippert 2023134655 Double-Lip Grease Seal Kit -- 5,200-8,000-lb Axles
Replace worn or leaking wheel bearing grease seals with this factory-matched 2-pack from Lippert. Designed for medium-to-heavy-duty trailer axles rated 5,200 to 8,000 lbs, these double-lip seals deliver superior grease retention and contaminant exclusion compared to single-lip alternatives -- keeping your bearings protected on every haul.
Wheel bearing grease seals are wear items that should be inspected and replaced every time you repack bearings -- typically every 10,000 to 12,000 miles or once per season for full-timers. A failed seal doesn't just leak grease onto your brake components; it lets road grit and moisture into the hub, accelerating bearing wear and risking a catastrophic failure on the highway.
Lippert part number 2023134655 (vendor P/N 08-7931) is a double-lip design, meaning it runs two sealing lips against the spindle shaft. The primary lip retains grease inside the hub; the secondary lip excludes water, dirt, and debris from the outside. This two-barrier approach is the reason most OEM manufacturers specify double-lip seals on axles rated above 5,000 lbs.
This kit ships with two seals -- exactly what you need for a single axle (one per hub). Order two kits for a tandem-axle trailer.
Primary lip retains grease; secondary lip blocks water and road grit for dual-barrier bearing protection.
Engineered for 5,200 to 8,000-lb rated trailer axles -- covers the most common heavy-duty single-axle and tandem setups.
3.371" outer diameter seats firmly in the hub bore with no shimming or adapters required on compatible hubs.
One kit services a complete single axle (both hubs). Always replace both seals at the same time for balanced wear.
Before ordering, confirm all three of these on your existing hub or axle documentation:
These three dimensions must match. Axle weight rating alone is not enough to confirm fit -- always verify the spindle and bore dimensions.
This seal is widely used on Lippert-manufactured axles found under many RV and trailer brands. Typical applications include:
If you are matching to a Dexter, AL-KO, or other axle with identical bore and spindle dimensions, this seal will fit those hubs as well.
