Has anyone had any problems or situations with there Richmond gear? I have an 89 GTA im gonna stick a 3:73 in, I know they whine a little but, do they hold up ok? any help would be appreciated!!!!!

 

They are prolly the best replacement gears on the market. Make sure to get street gears as the high nickel drag race gears wear too fast.

 

They are made exactly for what you probably plan to do with them (racing) so you shouldn't have any problems. Most premature failures can be traced back to improper setup/break-in so make sure you follow the directions VERY CAREFULLY and fill out the warranty card. I have had no problems w/ mine, nor do I know anybody personally that has either. Good luck.

How long is Break in?

 

I have the richmond 3.73's in my car, they were really noisy at first, then as they broke in they quited down alot... still a little noisy, but they are holding up nice!

My 3.73's have always been pretty quiet. Like they said, break-in and set-up is critical. The instructions have the break-in procedure. It amounts to driving it a little bit, let it cool off, and repeat.

I have Richmond 4:10 ring and pinion in my 70 Chevelle and they work fine. Even with 350 + Hp. I bang on em pretty hard and this is almost a 4000# car. Never had any noise either. I did not install them myself though I had a N/W Differential do the install. If your not familiar with this swap I would suggest having the pro's do it.
