I have a 2011 2ss with a 6 speed manual and I want to put 3.91 gears in it. Would that be a good set up or do I need to change the ratio to something else and how will this affect the driving.

Read more answer nowAsked by david on November 9, 2020 10:32 amA This is a great gear choice for the 6sd manual cars. You will still be able to cruise effortlessly down the highway. Will usually shift one more time than before when running in the 1/4.

Answered by the admin This will require some specialty tools that you will need to have. Bearing remover and press. A tool to spread the case to get the center section out. It isn't a simple job.

There really isn't much of a break-in process with the 3:91's as they are the OE gear. The only thing we recommend is doing a couple of short drives in them and letting them cool completely in between them. In fact, we do the first of the two before it even leaves here if we do the install.

Q What all would I have to change out for this set up? answer nowAsked by Martin Enriquez on July 26, 2019 1:59 amA Everything that's in the kit, should include everything you need. Once you under there, you may want to check the axle seals, etc to see if they look like they need to be replaced while you're there. Additionally, you would need the tune touched up for the gear change.

So I really trust your company I bought a cam from you couple years ago I’m looking at these 391 gears but I’m wondering the price of 400 something I’m seeing other company is it 3 1/2 or so. Am I getting more with your kit? And what do I actually need in the kit to have a shop install it?

Read more answer nowAsked by Ed on June 14, 2019 7:31 pmAnswered by the admin The kit should have everything you should need - shims are not included, some end up needing shims, some don’t. Our kit is a GM Performance Kit, not sure what brand the other kits are you’re looking at, but I would be cautious in what brand gears you purchase.
