I'm looking at nitro rear diff gear set and am windering if anybody has used them before?

Here's the link to it: http://www.justdifferentials.com/ind...249b09711766bb

 

you want to go from 2.73 to 4.11?

 

taking off in 1st gear is like taking off in 4th in a normally setup car. The recommended gearing for the combo of my cam with my transmission is 3.73 to 4.11. with the 4.11 in 6th at 70 mph I'll be at about 1800 RPM. I need to save my clutch somehow, lol. It's not strictly for DD either.

I'm also used to a very short 1st gear because of my truck, it has a "bump start" gear.

 

that makes more sense lol but i had a friend use nitro gears and didnt have any issues, strong and quiet.... he was satisfied

*on a side note, they should check there description for errors- "Street or stip" strip***

 

Sorry but what is a "bump start gear".I looked it up and there is only a reference to "bump start = push start" ???
Any way your not pulling stumps with a Camaro there for getting the most out of 1st gear is your best bet. Shifting into second a micro second after launch is wasting your hardest pulling gear. Beaning able to push 1st gear to its furthest potential would be the way to go.Not eliminate it. Thats one of the reasons 3.73s are so popular with manual trans missions.and 3.42s with autos.They allow you to have a 1st gear.

 

Thanks for the input. I'm going to look farther into them. I did notice a lot of typos in their descriptions across the site.

by 'bump start" I mean a very short 1st gear. usually shifting by 12-15mph, lol. When I use the calculator, there isn't to much of a difference of speeds between 3.73 and 4.11

This is showing with 2.66:1 first gear

I tried to make it look spaced out, but it keeps on defaulting

 

Looks like you have done some searching . Thats the same kind of stuff I do. I love doing a investigation on subjects.
Any way you might want to stick with a tired and true gear set.
Yukon and Motive gear sets seem to be popular.Richmond also but stick with there Street/Strip sets.There made for street with mild track use.The Pro-series is track only.

 

I'm in the mode of I only want to do this once, lol. There was a small discussion about what ratio I should go with in my build thread. I appreciate the concern to make sure I'm making the best choice.
