Backed by our guaranteed-fit promise.
This Lippert bundle combines self‑adjusting 12″ electric brakes with oil‑bath threaded hybrid hub‑drums for confident stopping power on heavy trailers. Rated 7,000 lbs per axle on standard axles and up to 8,000 lbs when used with true “8K hybrid” axles, the kit lets you upgrade or service Dexter, Al‑Ko, Rockwell and other 8‑bolt chassis without guesswork.
Verify axle tube rating, bolt pattern, and bearing numbers before installation. Maintain correct oil level and inspect brakes regularly to maximize service life.
