    What more do I need if anything?

    AaronC

    • The Yukon Gear Grizzly Locker Front Dana 30 can reuse your existing gears, as long as they are a 3.73 ratio or higher. You will need new bearings and an install kit to install this with the existing or new gears.

    How does the Grizzly locker differ from the Spartan locker?

    Greg

    • The Yukon Grizzly locker is a full carrier locker where as the Spartan locker only replaces the spider gears in your open differential. The spartan is only as strong as the carrier and x/pin. where as the Grizzly locker is a forged case and 8620 internals. Also the Grizzly locker Comes with Yukon's Best Warranty in the Business, 1 year replacement of part and up to $2,000 in collateral damage

      No worries

      Had this installed in the front Dana 30 of my Wrangler. It is completely unnoticeable on the street, daily commutes. Off road, locks up and gets me over anything I need to get over. The trails I'm on mostly offer mud/tree limbs as obstacles, not much rock crawling. The shop that installed mine specializes in Yukon products and said this was a great choice for a front axle. I got a great deal from Extreme Terrain and the shop had no problems with me bringing it in for install even if I got it somewhere else. If you're on a budget and can't afford a selectable locker this is a great option.
