Would this be worth the money to install? I can't afford a new strange rear. My car is a DD, but I'd like to take her to the track this summer. With the mods I've made, I'm not sure if the stock rear will hold up if I put sticky tires on it to track it. I was thinking of up-grading to 3.42, a deluxe install kit and this cover to help strengthen it. What do you think, do this or save for new rear? Will the bolts that come with the Ratech or Motive kits be better than OEM or buy the ARP rear bolt kit from Sumitt? www.thunderracing.com/catalog/?action=vshop&vid=4&pcid=210Here's the whole kit. www.thunderracing.com/catalog/?action=vshop&vid=4&pcid=68 |

They simply do not have enough meat on them to hold up to hard launches on sticky tires. The information you provided will help some by reducing flex and such within the housing, but cannot help the ring gear itself. There are some out there who have found the secret to making them last under these conditions, but I don't know what the trick is, and I know a lot more guys who have broken them than who have had success launching on sticky tires. My advice is if you plan to do this, start saving for a 12 bolt, and if you break it in the mean time, buy another 10 bolt or fix the stocker when it lets go, then keep saving for a 12 bolt. If you absolutely can't be without your car, since it is your daily driver, then don't launch on sticky tires; you will be on borrowed time. |

I second 1bad2k2ta's reply.... Sticky tires will kill your 10bolt, eventually. Im still waiting for mine to die again so I'll have an excuse for my fiance to let me buy a 9".

part of what causes them to die is wheelhop and not having the caps supported. ive seen 10 bolts in NA stock shortblock heads/cam m6 cars go mid 11s. i dont think hooking them up is bad. i think leaving hard on them is bad, wheelhop is bad, and leaving them unsupported is bad. wheelspin is bad because if you spin then hook it loads the rearend a lot more then just leaving softly and hooked up at part throttle. if you are careful with them, they will last. use the stock axles as the fuse, so if it does break something, its not the gears.

I bought a "Mac" cover from New Era, but it appears they are now selling the "TA" cover instead (same thing, different name, slightly more expensive): New Era TA GirdleIt's not going to prevent the rear end from blowing up, but it sure as hell doesn't hurt. At very least, it'll help your differential live as long as possible. |

That actually looks really nice but if you are runny stickies like everyone is saying stay away. My gears have a gasket leak so i was thinking while i have it up why not put some 4.10 gears in it. I dont take my car to the track, i just have fun with it on the street so i would have no problemo with a stock 10 bolt

Well, that reminds me. The other benefit is that these aftermarket girdles have DRAIN PLUGS!!! --Thanks to GM for not putting one on the factory cover.
I don't know why, but I HATE rear differential fluid. It stinks, and I can't stand getting it on me. I'm perfectly fine with engine oil and tranny fluid, but there's just something about that rear diff fluid...

yeah stickies and a 10 bolt dont usually get along and if you go to the track and break the 10 bolt the track people usually dont like that too well  |

Me and my buddy were swapping two rear ends and some of the diff fluid just poured all over my arm and it reaked to high heaven. Wow. It was stuck on my too and that night at the movies my girl friend was like WHAT IS THAT SMELL!?!? LOL.
are 4.10's bad for just regular street drivin? I have the 3.42's and like em!

I have the 3.42's and like em! i think the 4.10s are more driveable then the 3.42s. the motor is always in its powerband with the 4.10s. |

If I'm gathering the general consensus correctly, this kit is good because it pre loads the ring and pinion which reduces wear. It has a drain plug. It's a good step up from stock for DD and occasional race, but really hard launches will kill it with sticky tires. Thanks everyone.
