D Cepek Extreme Country Tires

[Super8mm]

I am looking at tires from D Cepek and in looking at their chart I was wondering about the OD for my stock suspension.

They list a 31x10.5 at a OD of 30.6 which is about what I have now.

Then they have 33x10.5 at 32.6 and 33x12.5 at 32.8.

Would the 32” tires be cutting it to close?

With your 4 popper, I would NOT go larger than those 31's.

That is coming out as soon as I finish the brakes and rear axles. it is going from 78 hp to 345 hp

That tranny and AMC rear end won't last long with that HP.

So true, I do have 2 SM465's and one it going to get rebuilt and go into it and I am adding rear disk brakes. To put the rear disk brakes on I have to pull the axles so I have a set of 1 pc axles to go into it too.

thats going to be a fun combo, welding on a back brace will help the AMC20 last longer as well as a traction bar

I dont think with stock suspension you can go much larger than what you have without a body lift.

long long time ago i got super swampers to fit my CJ with a body lift and no suspension

Thanks, I wont be doing any hard off-roading? but when doing FEMA inspections like I did in NC some of the places we go not all roads would be classified as roads plus a lot of debris. with that in mind I am looking for a beefy tire and these are on sale at 4 wheel parts now.

My BFG AT's are all cracking between the lugs so I will be getting a set of 5.

You are installing one of the beefiest 4 spds ever made so that shouldn't be an issue. The AMC20 has a bigger R&P than a Dana 44 , where the AMC20 falls short is the housing and two piece axles. Weld up the axle tubes, gusset it and add one piece axles and you should be good.

Thanks, I have the 1 pc axles that I will install when I do the rear brakes.

I do have a MIG, TIG, and stick welder so I can do the tubes too. I will have to look around and see what the gussets look like, I take it they weld on also.

I did the AMC20 upgrade (one-piece, tubes welded, disc brake conversion and a 4.10 ring and pinion), you don’t need a gusset if you’re not doing any hard wheeling. The weld will be plenty, he’ll, it’s plenty even if you do some wheeling. Just my perspective to maybe help you save some time and effort.

Amen to the AMC20 Weld up! That rear end gets sooo much bad press. Do a side by side part for part and you will be surprised. Leave it in, weld it up, and go! One piece axle swap for sure though.

So if I was to get this done ( I don't have a welder ) would the guts to the rear end need to all be removed ?

No they do not.

The other weak point to the 20 rear is the thin axle tubes.
A truss is pretty much a must if you have any intent to really use your Jeep in the rocks.

Nothing hard core, just want to beef it up a little more
