Complete spindle nut retainer kit that locks your trailer's wheel bearings in place, keeping them from shifting while allowing smooth wheel rotation. Sized for a wide range of axle capacities and built for universal fit across most trailer brands.
The Lippert 2023134656 is a complete 1" round spindle nut retainer kit, giving you everything needed to lock your trailer's wheel bearings securely in place. The 6-slot castle nut design lets you dial in the exact bearing preload, then lock it with the included cotter pin so it can't back off during travel.
This kit is engineered for universal compatibility, so it works whether your trailer runs a Lippert axle or a competitor's, as long as the thread size and washer dimensions match your spindle.
