------ Height Adjustable shift knobs! -------
At TWM we never rest. Our weighted shift knobs have been extremely well received and are regarded as a must for any tuner looking for the most out of their car. Most companies would be content with sitting on a successful product, however a few years ago, we saw the opportunity to make something great, even better.
Our engineers developed a system for fastening shift knobs to shifters that is unlike anything previously seen in the automotive aftermarket. ATIS Technology, in short, creates a factory-like threaded on shift knob (specific for each vehicle) which is height adjustable by an impressive 1.5" and does not need set screws to secure it to the shifter or orient its logo. So you will no longer have to live with a shift knob that rattles and comes loose due to those dreaded set screw systems.
ATIS stands for "Aluminum Threaded Insert System". Here's how it works:
Above is a picture which shows the contents of an ATIS equipped shift knob kit. First, you'll see the familiar TWM M1 Abrams shift knob (Gunmetal finish), immediately to its right the aluminum threaded insert, below it the black height adjuster screw, and below that is the Low Profile Jam Nut. Then to the right of all of those is the set of 3 spacers that we provide with every kit. Finally in the very back is our special tool that we provide to make installation a breeze!
The Aluminum insert is threaded on both its exterior and interior surfaces. The exterior thread pattern is the same as that of the inside of our shift knob. The interior thread pattern is specific to the application (i.e. Toyota, Mazda, Subaru etc.).
Here is another diagram which explains how the various parts interact with each other.
The first step is to select the spacer that will give you the height desired. You throw that spacer into the shift knob and then the Height Selection Screw is threaded into the knob. The special tool comes in handy here to get the job done without damaging the internal threads.
Once the above is completed and the spacer is in the shift knob with the height adjuster screw tightened down on it, it’s time to move to the shifter shaft. If you’ve ordered one of our engraved shift patterns on your TWM Performance shift knob, it’s now time to align it and make sure it stays!
The first step is to grab the Low profile Jam Nut and thread it onto your shifter shaft. Then simply thread the aluminum insert onto the shifter shaft. Once this is done, tighten the aluminum insert onto the jam nut and then thread the shift knob on. The shift pattern may not be perfectly aligned at first, but a few simple twists and adjustments of the Jam nut will net you a perfectly straight shift pattern that will never come loose!
Now it's also worth noting that if you'd like your shift knob at the lowest possible position, you can install the jam nut and the aluminum insert without the height selection screw or the spacers to assure the lowest knob height possible. This will be about .75inches lower than the stock shift knobs.
Here’s a picture that illustrates the height adjustability of TWM Shift Knobs!
