had my 4.77's from Ricks put in before the site went down. All i can say is that 2nd gear now pulls like 1st gear used to with 4.10's. Keith Nappi did the install in the No. VA. area, he is the best people. Had it done within 4 hours no problems no no noise. He uses his own Special blend of Diff fluid that is amazing. His years of experience on corvettes dont lie. Its too bad that he has now moved to the Tampa, Florida area so anybody around there deffinitly look him up, I will have new contact information for him if anyones interested. Best bang for the buck hands down.

 

Is it noisy?

 

Enjoy catching 2nd gear and being able to smoke the rears in first. This mod will make you love thrid gear and up hill turns! ENJOY

 

I live in Tampa and I am looking to build my stock rearend up with 4.77's. In my car now I have a Comptech reinforced housing, 4.57s, and a KAAZ LSD, all cryp treated. It is awesome but I have a stock rearend in my garage that I want build as a spare to play with.

Please have him call me at: (813)309-2696. I know a lot of Vette people and I do all the Deep Cryo Thermal Cycling for Vette Brakes and Products in St. Petersburg.

Thanks Jeff

 

I have a Brand New set of 4.77 from Rick's that have been Deep Cryo Thermal Cycling by Thermal Technologies in Florida for sale that have never been installed.

 

What does this have to do with under the hood?

I thought Keith Nappi moved to North Carolina for awhile???

 

Yeah I'll be getting some contact information from him hopefully by the end of this weekend for all you are interested in florida. He mentioned N.C. but he decided on Tampa for personal reasons. I'll Keep you updated

 

Thanks for keeping updated. He will be welcomed here in Tampa.
