Keep your trailer wheel bearings properly retained with this genuine Lippert replacement tang spindle washer. Designed specifically for 1-inch spindles with a flat (tang) side, this washer is the correct fit for Lippert axles rated at 3,500 lbs and under -- the most common axle size on lightweight trailers, travel trailers, and utility trailers. A worn or missing spindle washer can allow the castle nut to back off, putting wheel retention at risk. This is the correct OEM-spec replacement to have on hand for routine bearing service.
The tang spindle washer sits between the outer wheel bearing and the castle nut on your trailer spindle. The "tang" -- a small tab on the washer -- indexes into the flat on the spindle to keep the washer from rotating. This locks the castle nut in place and prevents it from loosening during travel. On 1-inch spindles, using the wrong washer (wrong ID, OD, or without a tang) can leave the nut free to back off, which is a serious safety concern.
Lippert part 119216 is the correct replacement for 1-inch flat-side spindles on axles up to 3,500 lbs capacity. It also cross-references as Keystone RV part number 214968, making it easy to confirm fitment if your trailer was built by Keystone (Cougar, Montana, Passport, Springdale, and similar lines).
Designed for 1-inch spindles with a flat side. The tang tab indexes to the spindle flat to prevent rotation.

Weighs just 0.05 lbs. Easy to stock as a spare during bearing repack or axle service jobs.
During a wheel bearing repack, the tang washer should be inspected every time. Tangs can fatigue, crack, or flatten over time, especially if the castle nut was ever over-torqued. A damaged tang washer will not reliably hold the castle nut, so replacing it at each bearing service interval is good practice and low-cost insurance.
