Jeep JK FAQ

Why do I need this kit?

The Jeep JK, in our opinion, is one of the best Jeep models to roll down the assembly line.  The factory just seemed to get it right with the beefy frame, big wheel well openings, nice interior, and the engine (ok, not really, we’re still partial to the inline 6).  Unfortunately, even though they made a pretty strong effort in the driveline, they still haven’t brought back factory installed lockout hubs.  When you install lifts, bigger tires, heavier wheels, winches, bumpers, roll cages the added stress on the unit bearing hubs leads to premature failure.  Until now, the only solution was to replace the unit bearing when they went bad.

What happens if a shaft breaks?

If your shaft or ujoint breaks, you must immediately change it or remove it and seal the axle tube.  Otherwise you risk doing more damage to other parts.  With the SpynTec™ kit, you can simply unlock the hubs and repair the damaged parts in a safe location.

Besides strengthening the front drivetrain, what are some other benefits of the JK SpynTec kit?

Of course being able to grease and maintain your wheel bearings is one of the strongest benefits to the kit, but you may also notice that the front driveline vibrations are gone and steering is improved.

You should also see a slight improvement to your fuel economy.  Customer feedback has suggested an average of 1.5 to 2.5 more miles to the gallon.

Why does the bolt pattern change?

The pilot hole on your factory wheels is physically too small to allow the lockout hub body to pass through it.  The 5 on 5.5 inch pattern wheels offer a much larger pilot bore.
