I'd like to upgrade my stock rear differential with the following goals in mind:

1. No more "one wheel peel" - LSD
2. Handle 600 - 700 RWHP - Forged or better than stock quality

So what would you guys recommend?

Doesn't the 09+ challengers have a LSD and stronger axles? You might be able to find one of those

Cheapest is the getrag but if you want something serious ...paramount 8.8

LX/LC 8.8 Rear Diff Assembly Paramount Performance Products

 

[MADDOG]

OK...Builder Bill is on my list to check out. I am also looking at the Mopar 3.73 & 3.92 Getrag conversions with axles & 2009 & Up LX driveshaft (maybe a chrom-moly upgrade) as well.

 

[Sodak]

Yep might as well get unlimated hp axels,And the reason i like the 8.8 gear changes are a snap and i have more choices. but not cheap.

 

[MADDOG]

Hell no it ain't cheap! Them paramount systems are 2x the price of an entire Getrag kit with 600 HP DSS axles.

So i take it this for the motor you wan't ,or are you going from the back of the car forwards.I.E. rear,trans,motor.

 

[MADDOG]

I'm gathering intel as I am going to do it all pretty much at the same time....engine & differential, plus some other mods I've had on the back shelf for some time.

 

[Sodak]

Damn... major build here ..Will be looking forward to this thread.

 

[MADDOG]

Who said there was gonna be one?

 

[Sodak]

There had better be one ... or the rest of us will vote you off this island.lol

 

[MADDOG]

hahaha....don't get yer panties in a wad bud. I'm just taking the first steps in what may prove to be a long, but interesting, journey.

 

[Sodak]

Ohh how i know about that journey ... and logistics

 

[MADDOG]

Logistics = Money

Research = Proper Parts

Proper Parts = Proper Execution

Proper Execution = Money

hmmmm.... weird how that works out.

 

[Sodak]

And hopefully you don't run short on any one of them ,then its get's fun

Well something to take into account.... Chris (lmi) is running 3.55 out back. He is running at about 2700 rpms on the freeway at 80 mph....I believe he has a builder bill tranny, but it might be SHR.... Not too sure....

He is putting well over 800 to the wheels with his setup. What transmission are you currently running? My nag1 will be toast once I get my Novi blower in.

 

[Sodak]

Yep thats a weak link as well,And yep just need more of the money stuff,Kinda why i'm staying N/A.

 

[MADDOG]

I know I am pushing the limits of what the stock trans will take so I'll be looking into transmission builds as well. I have a few friends out here that have done similar upgrades to their cars and one has a shop here...who is also an authorized DiabloSport CMR tuner. He's been through the engine/transmission/differential build more than a few times by now and I'm reaching out to him as well.

 

[Sodak]

Your lucky .. i get to take mine to a dealer. true they have done excelent work before ..but nothing really custom.
