96jeepcherokee X2 I need a 231 300 kit shipped to 23707. I don't need any additional parts to run the dana 300 driverside drop because of the different hole in the adapter ring right?

buildingabadassyj Duffy,

Is the 231/300 kit still available. I don't really need the shifters because I'm going to run triple cable shifters. And sort of discount?

dino30 At least your came with instructions ... Ive been left to fend for myself .... With no response to any of the questions ive emailed or called about .. absolutely Zero customer support . With a product that fills a gap in the market , if the support was there it would be a top notch company ........ But I recommend going elsewhere for a doubler setup , 1 for the support and 1 for the instructions ..

BLK97ZJ How much aft does it take? (I lost my directions)

CJ68 I hate to do this. Duffy is a good man and his products are great but... If he doesn't make an effort to correct his lines of communication then it is his downfall. Complain about bad cell service all you want. But get a land line in the shop to fix the problem.

Give these guys a call. Since Duffy can't be caught, I will probably eventually sell my old style 231 Box4Rocks and buy the behemoth D300 shorty kit. Don't PM me about selling my kit... I don't know when I will get around to it.

ol red Struggling to get ahold of Duffy. Anyone know a faster way or have an extra kit laying around?

greenman44 How is the response time these days with duffy?
11-19-2014 11:03 AM
CJ68 Just texted Duffy. Looking to convert my current box 4 rocks into the billet version. I have talked to him before. Once you get his ear, he is an awesome guy to deal with.

Here is hoping for a timely response .

Duffy im sure will have all the available options for you.Give him time to answer he's quite busy!
Does he have a website or something i can get on ? I have tried to find his company but I have had no luck . And I dont know if he is getting my texts . I have messaged him a few times in the past 6 months and nothing ..... I know yawl say he is near a base or something but there has to be a better way than just waiting on a response on here ....

dino30 I am not going to run an SYE , as i am building a 2 piece rear driveshaft.. The second part will have a slip built into it . When I go to the rear 4 link with coilovers i may be changing cases again . The main reason for this doubler is just to get my front driveshaft longer . Right now at full droop it will bind 3 inches before my coilovers bottom out .. Thanks for the info though ... And what spline count do I need to get ? the one from the cherokee or the dakota t-case ?
03-30-2014 09:05 AM
dodge doubler

Im building the same combo for my Dakota.
Use the Jeep t case in front and the Dodge case in the rear.
The 3 gear planetary is plenty strong for that purpose.
In front the palentary is getting the std torgue/hp load while the rear in lo lo gets double.
You will be fine in that configuration!
Let Duffy know the spline counts and he can advise further.
Note replace the rear cases out put shaft with a hd slipe yoke eliminator kit such as Advanced Adapters or JB Conversions!

dino30 Duffy ,
I am building a 99 Dakota .. It has a 231 HD t-case in it . Do you make a kit to build a 231HD / 231 LD Doubler ? The difference is the number of planet gears in the planetary .. Mine has 6 as the cherokee only has 3 . I have a 44RE trans , with the 5.2 V8 .. Please let me know , as this is a part i am needing to order within the next 2 weeks to finish my truck .... Thank you .

11-04-2013 02:52 PM
willysjeepseller I would love to buy one. But I'm getting pissed off because it's been 5 days of calls and texts and nothing. Horrible way to run a business.
