      Review & Installation Video

      Hey, Stephanie with here with the Rally Stripe six speed shift knob for 2015 and up GTs, EcoBoosts and V6 Mustangs. The Rally Stripe shift knob is a nice shift knob for the MT82 equipped S550s that are looking for a nice round type of shift knob to make a statement with. Now this obviously isn't a plain shift knob, and it's going to stand out for sure in the interior. A lot of people take advantage of the individualism that a shift knob can bring to the interior of a car. And while minor, the shift knob is one of the connecting pieces between the car and driver, so it needs to be comfortable. Now this particular Rally Stripe shift knob is black with a running pony on both sides here. But there are a few slightly different styles of the Rally Stripe shift knob. They're all going to have the race inspired Rally Stripes and six speed shift pattern, of course, but there's also a plain black version that's doesn't have a pony, and a plain black on white version as well if this one doesn't suit your taste. While they all are styled differently, they all have inlay engravings. And the engravings have been polished smooth, which is nice, because then you don't have to worry about fading. So there are a ton of different types of material to chose from when looking for a shift knob. The material and finish are definitely something to consider because different types of material have a different feel. Then you also have to consider how the material will react to temperature changes like the heat of summertime or the cold of wintertime. The Rally Stripe shift knobs are all made from a resin compound for strength and durability and none of them are sensitive to heat or cold like other materials can be. The shift knobs also have a two-and-one-eighth diameter, so they are a little bit larger than the factory shift knob. So these shift knobs are made for the S550, so they are reverse lockout compatible. They're specifically designed keeping in mind keeping up the pull up style reverse lockout mechanism, but they don't leave a large gap between the bottom of the knob and the top of the factory boot either. As far as price, these shift knobs are right in between $50 and $100, which is in line with most of the other options that are out there for this type of knob. There are some more expensive billet aluminum knobs that are also available if you prefer the look and feel of those. So the install here is really pretty easy. The shift knob doesn't come with any loctite and you're probably going to want some. So I'd suggest just picking some up before the install. The shift knob's obviously very easy to access and you're going to want to start the install by putting the car in reverse. This will help you get the height of the shift knob without any trouble. The factory shift knob just comes off easily by using the normal righty-tighty lefty-loosey rule and then it's just a matter of putting some loctite on the threads of the shifter handle so your new shift knob doesn't back out when you start grabbing gears. Then you take your new shift knob and thread it down into place until it gets tight, but then just do one rotation backwards to make sure you're giving enough room for the reverse lockout. You don't want to install the knob and then not be able to get the car in reverse. Just make sure that the knob is straight, so it doesn't look goofy later on. And then let it sit so that the loctite can set. It probably needs about an hour or two to be safe or an afternoon if you really want to be safe. Overall, this is a one wrench install on our scale here and should take just about five minutes to complete as long as we don't take the loctite set time. Wrapping things up there, the Rally Stripe shift knob is a classic eight ball style shift knob with a six speed shift pattern for the MT82 equipped S550 Mustang. It's reverse lockout compatible. There are a few different designs. They're all made from a resin compound and very easy to install. You can check these out more online along with all of your other shift knob options and for all things Mustang, keep it right here at

        White ball with stripes

        Really happy with this shifter ball. It's larger than the billet aluminum offered here, and the factory leather ball. Totally changes the feel if the shifting experience. Easy and cool mod.

        6 speed rally knob for ‘18 GT

        Been holding out for a while to pick this up; but now that it’s in I love it!!! Fits OEM shifter threads (meaning it should fit most aftermarket SS kits. Came w/ jam but, but I opted for locktite and fits and feels like a champ. It’s not the heaviest knob, but I’m ok with that; the style and feel are my major reasons for getting! Definitely recommend.!

        Nice Interior Touch

        I added the Billet Rally Shift Knob after installing the Barton Hybrid 3 shifter on my 2015 GT it feels comfortable in your hand and sets off the inside. The install takes just a few minutes.

        Rally Stripe Shifter Knob

        Love the looks and feel. Easy install, just remember to back off a turn at a time until shifter will go in reverse. Use Blue loctite NOT red. Throw locknut supplied in the trash, loctite works just as well and makes it a easier install, let sit overnight before using.

        Billet knob

        I love the look, size and feel of the shift knob but a bit disappointed by the edge where it bolts onto the gear shaft. Cleaned it up with a bit of wet and dry but the manufacturer could do a better job. Also used super glue to stop rotation as you cannot bottom the knob out on the shaft thread and the height is important with the reverse lock out. With the super glue you can still remove the knob with a little bit of force.

        Looks good

        This product looks great. Well made just doesn’t fit without modifications. When I installed the knob the reverse lockout was staying locked in. I’m still trying to find a solution.
