Hello everyone,just wanted to give my .02 cents on rear differential gears!
I have a 1996 chevy 1500 sport side that I bought brand new that I have done many bolt ons to! A couple years ago,I was thinking about putting some Edelbrock E-Tec heads on my Vortec 350! I called Summit Racing and talked to a tech support fellow to ask him about the heads. He told me a little about them and said for the H.P I was going to get it was a lot of money.(1200) He suggested that I change my rear gears. I was running a 3.42, he suggested maybe a 3.73 and it would perform as good as the heads and cheaper! I took the advice of the Guru at Summit, and what a big difference it made on my trucks performance! I went with Richmond gears and Eaton Posi ! (no more single wheel peel) some of the other mods I have on this truck are 1.6 roller rockers, Gibson coated shorty headers, magna flow cats, dynatech 2 1/2 true duals with x pipe, heavy duty big 4 core radiator, Mag Hytec differential cover, Dual Electric cooling Fans, MSD coil, Billett Distributor, Taylor Wires, Upgraded Injectors, Andy Granetteli mass flow sensor, K&N air Filter, Engine and Tranny tuned by Nelson Performance, BBK 80 MM throttle body(same as 454) With over 261,000 miles, this is still one Very Strong running truck! Gears for my Camaro in the future!!!

Gears are one of the best seat of the pants mods you can do. I love the 4.10's in my Camaro! Really wakes the car up.

Changing the gearing increases the torque at the rear wheel. This increases how quick the truck will accelerate, at the expense of maximum possible speed (which usually isn't an issue, unless you plan on running at Bonneville) as well as fuel economy (which, again, usually isn't an issue to enthusiasts).

As for being as good or better than heads ... I'm skeptical. They might, they might not. But in terms of cost vs benefit, I can see the appeal of rear gears.
