A Portion Of The Proceeds From Your Purchase Supports The Development & Reproduction Of High Quality 1963-1991 Restoration Parts.
The Mile Marker Premium Manual Locking Hub Set gives your 1974–1976 J20 the dependable, on-demand 4WD control it was built for. Designed for strength, precision, and serviceability, these hubs let you easily lock or unlock the front wheels for confident traction on the trail and smooth efficiency on the pavement.
Replacing your factory hubs with this rugged, precision-machined set restores proper 4WD operation and delivers a tighter, more responsive feel — exactly what Full-Size Jeep owners expect from quality hardware.
If you’re noticing any of the following symptoms, your hubs are due for replacement:
Front wheels dragging or binding in 2WD mode
Difficulty engaging or disengaging 4WD
Oil or grease leaking from hub seals
Clicking or abnormal noises from the hub area
Worn or broken internal ratchet mechanisms
¾-Turn Engagement: Faster and easier than standard ¼-turn hub designs.
Reinforced, Heat-Treated Steel Internals: Built to outperform and outlast OEM components.
Stainless-Steel Outer Housing: Exceptional corrosion resistance against mud, water, and salt.
Oil-Impregnated Brass Bushings: Provides smoother operation and longer service life.
Positive Detent Ball Mechanism: Ensures a confident, secure lock every time.
Installation Note: Reuse your existing mounting hardware to attach the black hub body to the brake/spindle hub.
