Curious, what is the reason for the “clocking”Its totally worth it. Im running a doubler with 2.28/4.7 gears and the options are awesome.
Check out Advance adapters for the doubler adapter. you can get them through poly preformance for around $370 I think.
Heres my 2.28/4.7 full 23 spline doubler to go behind a v6
Driveshafts made from 2.5"schedule 40 fit the stock joints well.
Happy to answer any doubler questions, Ive done a few of them.
This is a marlin doubler that is clocked 10* that I did a few months ago.
Ok cool. I just got my 5.29’s installed last week and I’m on 36 Tsl radials. So duel cases with stock gears is plenty probably since I have smaller tires tooI run both Cases with stock gears in my buggy with 5:29 and 39” bfgs. Plenty slow. I never take it out of low/low. 4th gear is like 1st in low only.
Also just found an 87 transmission and transfer caseI run both Cases with stock gears in my buggy with 5:29 and 39” bfgs. Plenty slow. I never take it out of low/low. 4th gear is like 1st in low only.
Is this the case I need?You need a gear drive top shift transfer case, or convert a front shift to a top shift. and an adapter, new drive shafts, and some floor board modification. in a nut shell.
Always fun to break down the crawl ratio.
(1st gear in trans) x (front case)x(rear case)x (axle gears)
My ratio is (r150f) 3.83x2.28x4.7x4.10 = 168.
If you had a w56, it would be 3.95x2.28x5.29 = 46 right now , stock duals 3.95x2.28x2.28x5.29 = 108 , or ultimate duals 3.95x2.28x4,7x5.29 =223
Of course it doesn't account for tire size or engine torque, but helps break it down a little.
the other nice thing about the 4.7 is it turns it into a 4 speed case. 1st is high 1:1, then stock low 2.28, 4.7 then double low of 10.7:1. 20 forward gears and 4 reverse gears. Where as with stock duals, its a 15 speed, with 3 reverse speeds.
"dual ultimate" gear layout
Black is transmission/transfercase gear ratio, red is what gear "overall"
" . 4th gear is like 1st in low only. " looks like some where between 2 and 3rd.
I mentioned adding gears to the front case, because my truck is a v6 so I had to convert everything to 23 spline. you wont have to do that for 4 cylinder (21 spline)
Well turns out it is $50 and it is a 7 bolt which is good. But the convert kit from TG is $250! Not including shipping. Think I may pass on this one and wait for the right one ...Count the bolts on the rear output . 7 bolts for gear drive, 5 for chain. (You want 7) Thats a foward shift case (rails come out the front vs a shifter out the top) it will work, but you would have to convert it to a top shift. People make kits for that.
Thanks for the link.Waiting is a better choice. Look on www.car-part.com - that t-case ranges from $100-$300 here in New England.
The t-case in your pictures will also need a rebuild given the bearings being covered in dirt and dust. I've bought used t-cases from the recycler that I could use as is.
