      Video Review & Installation

      Hey, guys. So today we're checking out the Yukon Gear Dana 30 Front Axle/44 Rear Axle Ring and Pinion Gear Kit with the Install Kit and a 4.88 Gear Ratio, fitting all 2007 to 2018 JK Wranglers, excluding the Rubicon model. Now this kit will be great for the JK owners who have upgraded to larger wheels and tires and want some gearing performance to match. Now when you upgrade to larger wheels and tires, you're adding a lot of rolling diameter to your Jeep and when doing so the engine does have to work a little bit harder to turn them if you don't have a gear ratio that's specific to your tire size setup.Now upgrading your gears will end up improving your fuel economy and improving your gearing performance when it comes to matching the tire size to the correct gear ratio. So not only is this great for trail performance and the daily driver, it's also great for the weekend warrior or even just the dedicated off-road Wrangler. Now there are a lot of ways that you can calculate your specific gear ratio for your specific setup and your application on ranges on what performance that you're looking for. Now one really easy equation is to multiply 0.12 by your tire size and that will give you a number to base your gear ratio off of. Now that's going to include a range from a lower numerical gear ratio for better MPG or a higher numerical gear ratio for better power and better torque. Now if you've landed at a 4.88 gear ratio, this will be a great kit to take a look at. This kit specifically will include the front and rear ring and pinion setup while also including the full installation kit, which is essential in order to get these installed on your Wrangler. Now this will include all of the new bolts, shims, bearings, and everything a need down to the grease Loctite and even a brush to get these installed on your axle.Now not to mention, these gears are going to be incredibly strong, made of an 8620 triple alloy steel, ensuring that these are going to hold up in the long run. Now I would like to call out again that this is not going to fit the Rubicon model because this setup is specifically for a Dana 30 front and a Dana 44 rear as to where the Rubicon has a Dana 44 front and rear, and you can tell that there's a big difference on sizing here.Now as far as pricing goes, this is going to come in at roughly $600 and I think that that's a really good price point for a fully inclusive kit. Now there are other options available on the page, and of course, some of those are going to be in different gear ratios, but they're really all going to be set up the same, it just depends on what they come with. Now this is going to include a full master overhaul kit and some other options may include that or they will only include a partial install kit. And there are other options available on the page that will only include any ring and pinions by themselves either together for the front and rear axle or separately. However, if you are specifically looking for an all-inclusive kit, you're looking for a one-stop-shop, then this is going to be a great choice. And Yukon is a very reputable brand, they make high-quality components, so you can ensure that you're getting your money's worth out of this kit.Now as far as install goes, I'm gonna give this a very big three out of three on the difficulty meter. This is going to require professional installation unless you have a lot of mechanical experience. This is not an easy job. Now this is very involved as well as the requirement of special tools in order to get the space and install correctly in your axles. So I would definitely take your Jeep as well as the gears to a reputable shop in order to put them in your Jeep and it will most likely take them about a day to do it. So again, if you are looking to re-gear your Wrangler and you're interested in a 4.88 gear ratio for your '07 to 2018 JK Wrangler, then this is going to be a great choice.And that's gonna wrap it up for this video.
