So I have a sparco shift knob with the three little screws, and every week or so it starts coming loose, I tighten up all three screws and then a couple days later it starts coming loose again. Anybody else have this problem and know if there's a way to fix it? Or is it just a negative to having an aftermarket shift knob? Thanks

btw, sorry if this is the wrong place to put it, i wasn't sure

 

THose kind of knobs suck. I can't stand them.

 

I posted this tip once, but can't find it now...try this: get a nut threaded to fit your shifter threads which is small enough in diameter to fit inside your shift knob. Slide this nut inside the opening of your shift knob...you may have to grind the corners of the nut down a little to get it to fit. Once in there and lined up with the hex screws tighten them down on this nut. Now you shift knob will screw right onto the shifter post like the OEM. In order to assure the nut is level inside the shifter knob, I've stacked it on top of some smaller nuts to get it at the right level, then slid the knob over the tob of this...worked really well.
I currently have my MOMO knob secured this way and it doesn't move or anything...very secure and stable. Let me know if you have any questions about the details above.

 

sounds like it should work, thanks a lot

 

I had a momo knob in my truck at one time and two out of three threaded holes stripped out. what i ended up doing was taking a pipe and threading the inside of it to the same thread at the gearshift. after that I slipped the pipe inside the knob with a even covering of red loctite on the outside of the pipe, inside of the knob.

worked like a dream and i think it took a hour total, no more slippies.

 

weird.. I have had two momo knobs.. one in the Tib and one in the Bimmer.. both used the three screw setup for holding them in place (and a rubber sleeve over the top of the shift lever) and the one on the tib did not come loose once in 6 years of ownership and so far the one in my BMW has not come loose either.

I expected better of sparco

 

that's a brilliant idea. simple and elegant. you dont even need any threading tools either, just a thin pipe and some vice grips.

i would also try going to a hardware store and picking up some tiny lock washers, but the idea above is much better.

 

The thin pipe idea is brilliant...hadn't thought of that. I'm sure it could be addressed with some careful planning and testing, but the MOMO knob I have has their logo on it and I definitely wanted to get it lined up straight...using the nut method allowed me to tweak the alignment of the knob to get the logo to end up where it should be.
Both suggestion will definitely address any slippage issues...with the added bonus of making it easy to remove the knob to work behind the dash or anything like that.

 

I had the "retaining cover" or whatever you call it also on my knob. i'm guessing we are talking about the one that goes on the bottom. but anyways, the only reason i did the pipe is cause i had the tools to do it at work and i hate to "wiggerrig" anything.

i'm going with another momo knob on my tib and will be making one for this one. I will make a note of it to make a DIY on it to show how i did it.

 

Bringing in this thread because I had the same problem but found an easy solution. I bought a Sparco shift knob as well.

I bought a M10X1.25 hex nut and grinded the crap out of the edges with a metal grinder. Took like 15 minutes. Just be careful wear eye protection and not take out a finger. Then I made sure it fit snug into the hole with the 3-screws. It fit perfectly. Then i hammered it in all the way and patched the holes up with JB weld. Then screwed those 3 screws into the nut as tight as possible. If you don't match the tread so that your shifter logo ligns up, just stick some aluminum foil into the hole and when you screw it in it'll fit snug pointing the right way.

The hex nut size for the OEM shift stud is:

M10 X 1.25

You can find it at home depot machine screw shelves. No more annoying screws coming off everyday and ruining your tread.
