[VTX CHF]

I went with the Hurst brand. Installed with no issues, follow the instructions and you’ll be golden

I just got a Bullitt knob, and it is surprisingly heavy. I expected it to be cheap plastic, but it seems like the exterior is metal with like a porcelain or powder-coated white surface. It's actually really nice - feels great.

It's not as heavy as an all metal ball, but pretty weighty. I wonder how heavy the stock knob is?

Just got it yesterday, have not installed yet.

EDIT: found the weights. The Bullitt knob is 214 grams and the stock is 142.

Note that Billetworkz knobs come in 2 weights. They are all anodized aluminum with the weighted ones...um...weighted.

If you want a bit of function with the aesthetics ...MGW

Just tried putting the Bullitt knob on, and like others have seen, it sits pretty high with a gap under.

Has anyone had any luck tapping it some to get it to sit lower?

I don't think it's bottomed out, more like it's got tapered threads and it's just tight. No way I can get another turn on it.

Thread size is 12x1.25.

I'm happy to report back to say that a bottoming tap fixed me right up.

I had a gap as big as the OP photo, so I ordered a 12x1.25 BOTTOMING tap.
I ran the tap down as far as it would go by hand one time, backed it out and it brought a shaving of thread.

Put it back on the car and it went down to the stock height. Lowered it by about 3/16". And it tightened up in an aligned position.

I think if I went too far, or ran the tap in more than once it might go lower, but you could always use blue loctite to stop it where you want. But I don't think I could go one more full turn and still have the reverse lockout work.

Hope this helps - and thanks for the tips.

My son went with this one:

I just installed the Bullitt knob, although there is a small gap between the reverse lockout and knob itself, it works completely fine. The gap is only noticeable if you’re looking at it from the side, so Its a personal preference thing really.

How many revolutions (turns) did you have to do to seat it?

What's a "bottoming tap"?

What's a "bottoming tap"?

A tap makes threads in a hole... most (standard) are tapered so that they can get started in the hole. A bottoming tap is not tapered so that it can make threads all the way to the bottom of a blind hole.
