2011 Camaro 2SS/RS - JRE Differential Upgrade, DEI Heat Shield, and MGW Shifter

Due to bad vibration from the rear end if the car while in the dyno, I decided to finally rebuild my differential to the Jannetty Racing 3.91 setup, added some custom DEI Heat Shielding, and even threw in a new MGW short throw shifter.
Also, found a leak on the transmission output shaft seal. Went ahead and fixed that while the drivetrain was apart.
Wheel alignment scheduled and then hopefully hitting the dyno again soon.

The z28 axles fit the SS pumpkin?!

[@allenwoolsey]

They sure do 😎

[@mikewozawski1634]

Hey where did you source the axles? I cant find them and need oem ones having problems with aftermarket. And my 1le oem part # is discontinued. Cars been down months

[@allenwoolsey]

I got lucky and found a place that had them still in stock. I believe I took their last ones. Sorry that isn’t much help.

[@moose1992caprice]

How has the diff held up? Do you have a parts list of what Jenety installed?

[@allenwoolsey]

The differential is awesome! Feels great with the 3.91 gears. Here is what they included: 2010-UP CAMARO SS 3.91 GEARS SET 2010-15 CAMARO REAREND INSTALL KIT 2010-UP CAMARO SS TRUE TRACK POSI UNIT 2010-15 CAMARO BILLET MAIN CAPS 2010-15 CAMARO REAR DIFF GASKET 85/140 GEAR OIL QT 2010 CAMARO PINION SHIMS .6096 -.7112, .024-.028 JRE BUILT DIFFERENTIAL, NEW RING AND PINION, EATON TRUETRAC POSI, JRE BILLET MAIN CAPS.

@@allenwoolsey what was the cost? I’m coming across I need to do the same.

[@allenwoolsey]

@@Folsomfamracing the price was just about to increase when I purchased. I’m sure it’s now over $3k, but you will need to contact them directly to get a correct price.

I just upgraded my 2010 Camaro to Yukon 4.11ring pinion, Yukon master rebuild kit with Truetrac. Total parts were $1600. JRE quoted $3200 complete so they charge $1600 labor which is ridiculous. I always thought it was voodoo but it's not. Downloaded the Yukon install instructions and read all 20 pages and watched a bunch of videos to prep. Once the diff was out of my car, took about 4 hours to swap parts and my ring gear paint is textbook, better than the mona lisa. @@Folsomfamracing

[@josephgagliardo6088]

After the Rebuild of the diff did you still have the slack/Lash when turning the pinion back and forth?

[@allenwoolsey]

I did, but not nearly as bad. It’s much tighter now. Not sure if that is due to better internals or cause of the wear of the old ones. Either way, it’s so much better now 😁

[@jimmyfreeze3782]

I sure hope so because every differential requires it. The new one will be the same after break in.

[@GOD2FAST]

Why 3.91 over 3.73?

[@allenwoolsey]

It was what they had in stock. The 3.73 would have been a longer wait time.

Part number for the heat shield material

[@allenwoolsey]

Hey Robert. I just ordered a roll of their stick on heat shield material. I don’t remember the part number, but it was just a generic roll.

[@mikewozawski1634]

My driveshafts does the same thing i think its normal

[@jimmyfreeze3782]

Yes it is. It's called backlash required for all differentials.
