37s mounted onto rear axle. looks cool.

Need to know a couple things before I can move on (aside from waitin on calipers)


Slip yoke, how much spline movement should be allotted for? 1" of inward thrust when mounted to companion flange?

which "yoke" will bolt up to the superduty companion flange.

yah 1" should be good, i dont imagine you are going to be on a high travel susp setup

I still think you should get 4.88's but thats just me.

I plan on running 35s again honestly, the price of 37's vs 35s is a major turn off and concern over the long run.

thanks pat, glad I'm not the only one agreeing with myself... :D

Just out of curiosity, why are you performing the SAS to only run the same size tires as you are now on the IFS lift? 35's don't eat up the stock front end that bad, at least in my experiences.

it will still be awesome and i wish i had the drive to do this to my truck, but to me it seems like a lot of work for ultimately, less true ground clearance than you have now. perhaps you desire the stonger hubs/bearings for payloading? or maybe a true manual locking hub system the IFS won't provide? better articulation, or ease in pulling the oil pan?

ahhh MiniMe... :D

Better payloadability with the camper, plus then I can stuff my brothers toys and my bike in his 21ft trailer and be pretty well set, and then grin from ear to ear not worried about that rear axle. The brakes in comparison are monsters. better articulation will be more appreciated than ground clearance.

plus haven't you noticed I've blown that 8.8 apart too many times? I wouldnt wanna jump to the 9.75, do the same think or worse imo, send a shaft out the tubes.


If I SAS, and run 37's I really dont know if I could ever get under my camper again...

Why don't you do the 37's then make a platform to raise the camper on, the lift difference in 35-37's is only 1". I agree that the swap is a ton of work for 35's a lot more than id do.

yeah, you've popped the poor 8.8 like four or five times, right?:D i'll admit the 9.75 is not invincible, i currently have a bearing in mine on its way out. makes a very annoying whine, lol.

i admire your hard work and dedication, though. are you gonna run coils or leaves up front? i imagine you'll have to weld in a new, low profile crossmember, and cut out the ifs frame crossmember running such little sas lift to give room for optimal articulation without interference. the brakes on the new axles will probably a vast improvement over what you have now, i hadn't even thought of that.

if i had another vehicle to cruise around town in while my truck was torn down, i would probably perform a swap like this myself.

I may do 37's I just worry a bit about the overall cost of replacements.

If you can get 16.5" rims, you could run 37" military goodyears, a set of those are usually cheaper than a set of decent 35's.

...

I have those going onto my B2 (budget trail truck) because my parents bought a set that shook so bad above 35mph that the truck literally started to move out of the lane.

Bad experience = No go for me. Pretty scary when you consider their truck is a 2000 f250. May just been a bad set but wheres the guarantee I wouldnt get another set like that :lol:

ive never like the military 37's ive never had much to say about that. they suck majorly in mud.

are you gonna cut and replace the old IFS crossmember? I would imagine you would have to for clearance reasons. Remeber to make the new one before cutting the old one out of the frame will spread out.

:lol: well thats probably why they're cheaper I guess. I've heard of people having trouble balancing them but didn't think it was that bad.

Yeah :lol: probably why, they were friggin terrible. I mean my dads had run ins with crap biasply in his days but he even said those took the cake with that performance.

I've heard they are crap in mud, act like chalk in rocks just chunking apart.


Trimble, I have been wondering if I have to knock it out or if I can notch it heavily. time will tell, as you seen I have no room there, so I'm still waiting on getting it out to the slab where I can work easily. Plus I'm still waiting on parts :(

Looks like a promising vendor, http://www.driveshaftsuperstore.com/
