🔩 TruRyde® FA-7-187 Greasable Shackle Shoulder Bolt
The TruRyde® FA-7-187 greasable (wet) shackle shoulder bolt — the serviceable counterpart to the FA-7-126. The zerk grease fitting allows you to pack the bearing area with fresh grease at each service interval, extending the life of the bolt and shackle link in high-use, high-moisture, or corrosive environments.
For applications where greasing is not practical or preferred, see (FA-7-126) — the dry/non-greasable version.
