Anyone install a GKN Visco-Lok rear differential in a Gen 3? Or any information doing this?

Thanks...

Yes, did it to mine last year. Very impressive on the street and the track. I just ordered a differential with gears and unit installed and then swapped with original unit. What # is your commemorative?

I'm #019 with an OE Gen. IV hood, Calchromed 5 spokes, drilled and slottled Eradispeed rotors, and Corsa. My next upgrade will be a gear/differential swap.

I Did also and put in 3.33s. Great upgrade. Car is much more predictable when heavy on the throttle.

I have a Unitrax built Visko-Lok diff with 3.55s in my 06...great upgrade, although I would do 3.73s at my near stock power level if I had to do it over again.

Ill give Unitrax a call today to see what they have. Also my 05 Commemorative Edition is #83 and Love it!

Just spoke to Devin at Unitrax and I think I have a great option on a Wavetrac unit. We will finish up the deal next week and Ill have my mechanic install when the new polished intake is being installed. Devin was great to talk with and lots of information on ideas and past experiance. Thanks...

Awesome...you'll be happy. What ratio did you go with?

Sticking with Stock 3:07's since I already have a paxton installed.

Herb Helbig (Retired Viper Chief Engineer) addresses this question in the latest Viper Magazine. Explains the benefits, and engineering advantages. He suggests it would be best to replace the entire axel assembly in 03 cars.

Ill have to look at the article....But is this just a 2003 issue or all of the Gen 3's (03-06)?

 

[Paul Hawker]

Question only asked about 03 and 96. For 96 Herb recommended replacing the axle shafts too.

I had a Paxton on my 03 and blew out the 3;55's. Replaced them with the stronger 3:07. Still had enough torque to blow off the tires when the revs were up : >)

You might also want to consider a Giken. It is a very robust piece. I have one and I am very pleased with it.
