This is a 7/8 inch lock nut with a fine (7/8"-9) thread, designed to secure the equalizer bolt in a trailer's leaf-spring suspension system.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Its locking feature—often a top-lock or distorted-thread design—prevents the nut from loosening due to road vibration, helping keep the suspension linkage safely assembled. It is commonly found on trailers with 5,200 to 8,000 lb axles and 2-inch-wide slipper springs. Replacement is recommended whenever the equalizer bolt is removed for service, or if the nut's prevailing torque is lost.
