Overview
The G2 Axle and Gear 89-2034-1 is a pair of Dana 50 and Dana 60 Extreme manual locking hubs in polished aluminum, built for 30 spline axle shafts and suited to most Dana 50, Dana 60 and Dana 61 axles.
G2 designs these freewheeling hubs as a direct replacement for factory hubs and says they provide the strength and reliability needed for heavy off-road use. The body is nodular iron, which G2 says resists impact. The lock ring is heat treated steel, and the cap and dial are aluminum and alloy, which G2 says resist corrosion.
The hubs carry a lifetime warranty from G2. They are built and tested for extreme conditions.
A manual hub of this type lets the driver unlock the front wheels from the axle for normal driving and lock them for four-wheel drive.

Locking hubs and daily driving
Manual locking hubs let the front wheels spin freely from the axle during normal street driving, and lock them for four-wheel drive. The lock ring and dial are the parts that see the most use, so keeping them clean and moving freely helps the hubs engage smoothly when needed.
Before installing, confirm the axle shaft spline count, since mismatched splines will not engage. Aluminum caps and polished finishes look good but show road grime, so a regular wipe-down keeps them presentable. Check the hub seals and gaskets for leaks during service, and use the lubricant the axle calls for to keep the bearings protected.
- Lock and unlock hubs on a regular schedule
- Clean the dial and cap after muddy trips
- Check seals for grease or water intrusion

Vehicle fitment
G2 labels the 89-2034-1 hubs universal for most Dana 50, Dana 60 and Dana 61 axles with 30 spline axle shafts. G2 gives no model year, vehicle or chassis code.
The hubs are made for 30 spline axle shafts, so a 35 spline shaft will not match. Check fit against your axle’s spline count and vehicle before ordering.
Installation notes
A vehicle with 3 bolt automatic hub covers will need 2 each of part numbers D/S621027, D/S660568 and D/S621028. Check your axle’s spline count before ordering, since these hubs are made for 30 spline shafts.
