We still have not received any confirmation from GM about these gears, but it should be soon. I will update this thread once I have more info.

And yes, they will work on the L99. Please feel free to call, PM or email me anytime with questions.

awesome ill have the payment ready

Please pm me when these are ready to ship. I will have payment waiting. Thanks!

Does the gearset only work with 1le camaro? I have a 2011 2SS/RS

It will work on any V8, both auto and manual and the V6 if it is a manual transmission.

True on the v6 part since we share the same diff as the L99/SS.

Please pm me if these are in stock. I have money sitting aside for gears and install kit.

They fit any SS, not just 1LE.

Hey guys, we just received our shipment of GM 1LE 3.91 gear sets! We have 4 sets left in stock ready to ship! Please feel free to call, PM or email me anytime with questions. :chevy:

Can you PM me on the re-cal of the ECM??? as not to avoid my warranty.

I'd like to know about programming my computer for the new gears as well. Pm me please

Reprogramming the speedometer will either require tuning, or sometimes the dealer can take care of it for you. Please feel free to call, PM or email me anytime with questions.

Looking to upgrade my rear end.

I wanted to swap up to 3.91 gears, but was also wonder, to avoid Launch Control issues, along with new gears, what else should I be looking to replace to re-enforce? Axles?

A PM would be greatly appreciated. I wanted to get some numbers together before ordering gears.

Thanks!

Can you PM me an estimate on how much installation would cost?

Hey Tyler,
On page 1, you said you had a differential exchange program. Is that still available? I dont see it on your website. Do you offer the TruTrac as an option? I have an extra diff ready to send. I want all bearings replaced, TruTrac, and 3.91 or 4.10. Is that possible? Thanks!

We are working on getting a complete price system going for the core exchange. Please send an email to sales@jdpmotorsports.com with the options you would like, and we will get that pricing for you ASAP. Please let me know if you have any questions.

Best regards,

im almost ready to order too, are they in stock?, does any warranty be void if i change gears? as if i take the car to the dealer to tune the gears and will they void my warranty if i told them i have gears installed? and pricing for shipping to Puerto Rico.

Thanks

Yes we do have one set left in stock. As for potential warranty issues, you should not have any as they are a Genuine GM part, but you may want to ask your dealer as some dealers have different policies and views on things.

As for shipping to PR, please send me a PM or email with your full shipping address and I will be happy to get you a quote together.

Best regards,
