Im looking to get some gears pretty soon, and I was wandering if the rear end gear package from thunderracing is worth the $. Should I just get the gears for $200 or is the rear end cover worth the extra $200?

 

I personally don't have one, and never will. I've heard these are really only if you're street racing and only complement other parts like a new sway bar. If you're going to be racing enough to worry about your rear, you're better off investing in a 12 bolt or something similar. just what i've read and heard first hand.

 

i have one on my car and have made 30+ trips down the 1/4 with 295's and mods in sig along with a few burnout competitions and a lot of street racing, still going strong. It doesn't whine or clunk and i also have 4:10s

 

When I had my 10 bolt I had one. I got the one from Spohn for $139. I guess every little bit helps when it comes to the 10 bolt so I got it. If nothing else it sealed great and made for easy fluid changes with the drain plug. I never broke the rear running 11s, so I guess it may have helped.

It looks like it adds some strength to the rearend, but more so adds some visual character in my opinion.

 

its worth the so called "added insurance".. i put one on with a stud kit during my 4:11 swap

 

before i knew better i put one on my car, still broke the gears. i was talking to allan futral (futral motorsports) and he told me that the girdle was a waste of money, it is more for side to side stress or something along those lines. basically he told me for drag racing it was a waste and that he never does them. as far as breaking gears goes, there is no way to tell if it really helps or not. i broke mine with a girdle and stud kit, on the street on hankook radials and i have a buddy that is making 439 rwhp and races on nittos without a girdle and he has never had a problem

 

FWIW, I'm going to do a gear swap shortly. The mechanic who will do the work (formerly with GMMG) advised that, in his opinion, the girdle was a waste of money. He hasn't steered me wrong yet, so I'm not getting one.
