49" Iroks with a d60 and 14ff

Re: 49\" Iroks with a d60 and 14ff

Makes sense to me why youd want 44s off road. If you clear the 49s on road, instead of getting them to clear off road, just put 44s on and tghey will easily clear off road.

Re: 49\" Iroks with a d60 and 14ff

I have considered Rockwells and I researched it a while back. I didn't like the low gear of Rockwells due to driving on the road, but if I am comtemplating 49s the low gear is really not an issue. I decided against it due to the amount of work needed or is it not as much work as I am thinking? Aren't they top loading axles and you have to have a lot of clearance for the diffs and I don't care the idea of pinion brakes either, etc.

I am not above putting the money in or doing the work if it is necessary, but I am not going to put Rockwells under my truck just so I can drive 49s on the road, 44s will do fine, but if there is a feasible way to 49s now with 1 ton gear, then I would consider trying it.

Thanks for everyone's input I really appreciate it.

Just buy them and run them. One ton gear is fine even off road, so you break something periodically....so what? You'll break SOMETHING offroad even if you go with rcokwells. I think 49" Iroks would be awesome. /forums/images/graemlins/peace.gif

Ditto.
 
Re: 49\" Iroks with a d60 and 14ff

I have a different question - will your braking system be up to the task of stopping 49"s safely - there are a lot of idiots on the road that you better take into consideration. That is a huge tire and lots of weight to contend with.
 
Re: 49\" Iroks with a d60 and 14ff

I think that I might just try 49s then. But does anyone else have any response to my question about running in low range on the street?

That is a good question. I don't know the answer though. Will my brakes be up to the task? Everything in the brake system is stock with one ton axles, and I have rubber lines. It stops plenty good now, I have never wished that it stop faster. When I have to get on the brakes now, it stops fast enough that there is so much body roll that it feels like the rear tires are going to go in the air.

and even in Peterson's they pout the 49s on a Blazer with a d60 and 14bff and a big block and it survived (but it was light weight).

it's not an blazer It's an K-30. I've talked to the onwer (randy) a few times. His rig weighs around 4,300lbs the cab is moved backed about 12" or so. he has an 496ci BB with an sm465 1 tons 5.13's and lockers front and back and an 6" lift. He dosen't break much but his rig is real light. And he only runs mud. I've seen that truck in action plenty of times in person and it's bitchin. I'm sure you can do it but your going to have to do alot to run them. good luck and make sure to take some pictures when it get's done.

here's a K5 with 49's and 25" springs.
 
Re: 49\" Iroks with a d60 and 14ff

Got 2 buds who both went from 44's to 49's this past spring.

The orange/yellow had 9" lift and a 60/60 with 5.38? gears. It hasn't been out much with the new setup but seams to be holding up well. Its mostly a trail rig.

The other is a compatition mud bogger/backup trail rig and has a huge lift. But he has built a complete sub frame that lowers the engine, tranny & Tcase. He is running a 60/14 with 4.56 gears and 35spline outers. As far as I know he hasn't broken this year.

Re: 49\" Iroks with a d60 and 14ff

personally, I wouldnt burn $2000 worth of rubber on asphault "just for looks", but if you got the cash, by all means, go for it. If you ever drive outside your own state, you'll prolly get pulled over a lot, but its all good!

I wouldnt run anything heavier than a 42 on a standard D60 with 35 spline outters personally, but others do it all the time. /forums/images/graemlins/thinking.gif

Re: 49\" Iroks with a d60 and 14ff

i couldent say for sure but for the street you wont snap anything, so if it turns out to be a little gutless you can go from there.

The ony real consern is this, dont iroks wear down rather fast on the steet, so unless you have a huge amount of money why not go to a tire that wears better, since your swaping out for the trails anyway /forums/images/graemlins/dunno.gif

(not meaning to offend anyone) if you are going for looks with 49's I think that is a little odd because IMHO anything bigger than a 40" looks just plain stupid on a short wheel base truck. Big tires belong in the mud, plain and simple. I've ran 35" boggers 75% of the time on the street so I can't talk alot but at least they werent $500+ bucks!

[/ QUOTE ]
Except for the fact that 49s make most rockpiles look like a joke. The comment big tires are meant for mud is really stupid from someone who doesn't mess with rocks. And the comment that you need lower than 5.13s I'd agree with, the comment that EVEN with a TH400 is really stupid. Th400 has higher gearing, if anything you will need MORE gear with one /forums/images/graemlins/rolleyes.gif.

[/ QUOTE ] Rocks mud what ever, I don't give a rip, they belong offroad. Sorry Rjfguitar it sounded like you were saying 49s had no place in the rocks only the mud.

My cousin always brings that up with my blazer. I dont think its all that necessary, its not like I smash around corners. Does he notice a big differrence in handling?
 
Re: 49\" Iroks with a d60 and 14ff

The biggest thing that would concern me is safty. Seems your rig would be real top heavy (high center of gravity)cornering would be an issue.
 
Re: 49\" Iroks with a d60 and 14ff

You will snap axles in the Rockies. Check the latest ed. of Fourwheeler and look into the TTC. The yellow Jeep, JEEPZILLA broke his rockwells at least 3 different times in the entire competition. I remember when the boys at Avalanche Eng. snapped their rear 2.5 ton rockies with 44" TSLs /forums/images/graemlins/shocked.gif
 
Re: 49\" Iroks with a d60 and 14ff

Well I think he moved it down mostly for drive shaft angles since he uses a blazer frame. He built the truck long before H.A.D.or those 80 degree CV's. I beleave he told me everthing was droped 24"...but not sure. He does claim that its very stable compaired to other rigs of its size. Dern thing does looks tippy compaired to my 84"tall 88"wide hybrid on 44"ers.

Well you gain many things with 2.5 ton rocks but axle shaft size realy isn't one of them. The axle shaft u-joints are much bigger but the shafts themselves are only 1/16-1/8" larger on the diameter. Now if he was running those 40 spline upgraded shafts than that would be impressive.

rockwells are old axles and use old technology. The shafts are not modern forged technology.
 
Re: 49\" Iroks with a d60 and 14ff

Last I heard an 49" Irok didn't weigh much more than a 44" tsl so why is it everybody thinks it spells certain death for a 60?
