I've noticed that my 10 year old shifter doesn't have the centering spring action it had when new. Anybody ever rebuild theirs? I just emailed partspro@live.com who looks to be the reps/manufacturer's of the Pro 5.0 shifter to see if they have a rebuild kit.

 

No, but I'm curious. The only mod on the LT1/T56 powertrain in my Vega is a Pro 5.0 and I've heard they get sloppy after awhile. It'd be cool if a rebuild kit is available.

 

Pro50.com sells replacement springs (2) to rebuild the shifter. $25 (min purchase); rip-off price but still cheaper than a new shifter. Pro50 has a very limited product line so I didn't find anything else to buy to meet the $25 minimum.

 

Before I did that I'd go to a local fastner company like Fastenal, Grainger, ect. and find some springs that will work.

 

It's going to be hit and miss to get the correct spring rate. Not looking to rebuild it multiple times.

 

It's not a Swiss watch. Going with the same wire dia. and number of winds will get you close. You could even step into a machine shop with the springs and have them check out the spring rate before you install.
Or just spend the money for them from Pro.

 

My Pro 5.0 is still serving me well in my 99 SS. It's been on there for like 10 years.

 

McMaster Carr or Grainger and grab some springs that are the same physical dimension and replace them. I grabbed a few different rates when I did mine years ago and found a force I liked that worked. It was actually stiffer than the shifter in stock form, but I liked it better.

 

I rebuilt mine with the Pro50.com springs; could not tell any difference! I noticed that the springs sit on metal disks that interfaces with a cross rod mounted to the shift lever. I had a friend machine me a couple of matching disks that i used as spacers to increase the spring force. Worked like a champ!
