I need some opinions for a daily driver

I drive mine all around, everywhere, and it's sitting (technically it's higher - this is on paper) 6.5" up on 35s with 4.88 gears and dual lockers. If you like to drive off-road vehicles it won't matter that on road it's a bit of a brute. If you are looking for a Cadillac ride with Corvette handling, well, I got news for ya. :D
 
a High Pinion 30 will last just fine on 35"s. it has a stronger ring and pinion than a LP 30 because the pinion runs on the drive side of the ring gear.

the only thing gained with a d44 is a stronger R/P since the shafts are the same.

if you truss the axle from C to C to prevent ring gear deflection it will handle quite a bit.

This is what I was saying. Truss it & you should be good. I always thought 33's were the limit on the Hp D30's..I do go fast stuff though, so I always try to over build lol.
 
I know its in a YJ, but here is what an HP 30 can handle built. 35"MTRs warn hubs Chromo inners and outers, ARB geared at 4.56, CTM's, sleeved and a 3/8" truss that goes from spring plate to spring plate

FYI these pics are from Johnson valley are pre- sleeve and an older truss system.

but the axle is still on the jeep (9 years running) with nary a broken part :knockonwood:

Steve, Ive been running 33s on 4.56s for many years while daily driving it. When I had a chance to get 35s I passed to opt for better highway and less chance of breaking anything even though I'm easy on the skinny pedal. 33's will get you through a majority of the trails with lockers and good driving (Rubicon, clawhammer, aftershock, Pritchett cyn in Moab, etc)

Once I upgrade the axles to something other than the 8.25 29 spline / HP D30, then i'll go 35s. I'm sure I can run 35s with no problem but I err on side of caution
 
Yea, your setup is really fine for 35s but I hear ya. Really, the weakest part is of course the factory D35 (ouch) and those dang joints on the 30. Once you step up to the big 760s things get a lot smoother. :)

I daily drove on 35's and 6.5" lift for several years with no problems. I handled the jeep like it was a newborn kitten, and would baby it on the trail. It was never jumped, and rarely did the engine exceed 2500 rpm's. I did come home on a flatbed twice, once I broke a distributor (wtf..?) and the other a cheap brake caliper failed - I didnt feel up to driving home without front brakes.

If I kept my foot out of it, I could get up near 20 mpg, but usually averaged 17 or so. It was comfortable to drive, and with WJ steering and bilstien shocks handled like it was on rails.

If you're looking to watch the economy, go with lighter skinnier tires (33x10.5) and avoid doing a roofrack. If you want to keep the ride soft, don't do a rear tire carrier (you may have to if you want to fit the dog in back..).
 
cal did the rear tire carrier really make it a rougher ride? I've got 7100's up front & will have WJ steering pretty soon. In the rear its got some crappy Rancho's but will soon have 5150's or 7100's...Its 4.5-5" on 33x10.5x15's.

I really wanted a rear tire carrier because I enjoy bringing the dog & having the extra space back there is nice. I'm contemplating a smaller roof rack with the tire up there or a swing out rear carrier w/ jerry can mount.....
I was thinking tire up top w/ roof rack= high COG. But I could remove the tire & jerry can during daily driving. Stillhigh COD even if its a minor difference.
Tire out back w/ carrier & jerry can mount= more weight over the rear axle to keep the rear end down when doing go fast (jeepspeed) type stuff. But I don't want the rougher ride!

It's more of a jeepspeed style rig, but I do camping/fishing & everything with it! What route do you think I should take? Roof rack or rear tire carrier. I've been thinking this over for a while.
 
Bigsteve, I know this isn't every body's experience, but I've been dding my 89 since I was 16. First with 33s, blew up the Dana 35 (expected) and for the last dew years I've been at 5.5" & 35s. No wreckage after a few trips to Moab. In my opinion, a trussed, covered, and locked hp30 can handle 35 inch tires all day. It is true that you loose strength in gears as you go up, but I run 4.56 gears and I feel that it is great for daily road work and in low range on the trail you hardly notice a difference between those and 4.88. Just my opinion.
 
Seems your safe for 35's:wave: These guys are crawling with exactly what you want, so follow whats been done & you should be safe.:thumbup:

I did the research before stuffing more than $4,000 in parts into a dana 30. As many if not more 4.56 gears have been reported on naxja than 4.88 gears.

At the end of the day, the biggest culpret seems to be running a stock carrier with a lunchbox locker. The carrier is flimsy and will bend, allowing more gear deflection. Following that, truss and sturdy diff cover.

YES IT DID. I had the rear tire carrier, and if i were packing a bunch fo people in to go camping, would put the tire up there so I can load up.. but for 99% of the trips, the spare was in the cargo space, on top of the folded down back seat, as far forward as possible.

Having that much weight that far back made a HUGE difference - not just offroad, but driving down the 91 freeway it was a big deal.

.. Tire carrier, no tire. This was a pretty typical thing to see. I used the tire carrier maybe one weekend a year after I went to 35's. Even with 32's it was really noticable.

I run 4.88s, and I run them rather hard when I trail. No issues, but then again, not to toot my own horn, I know how to drive. Sure, I've busted axles and other things, but that comes with the territory. Stay off the skinny pedal and that 30 will take a lot of abuse. :)
 
Man that sucks.
My account (casual) is kinda for 2 people. Me & a buddy. We are doing his rig into a 2wd for jeepspeed type stuff. I'm keeping my 4wd cause its a all around rig/jeepspeed.
But after reading about people doing trail runs & stuff, I think I may stray away from doing the jeepspeed stuff & start getting into rock crawling. It seems like the family & I would have more fun doing it, meeting more people & such! I wanna do the cooking at So-Cal fest, so maybe I can catch a trail ride or something!
I've never even been in a rock crawler style jeep let alone had the experience lol. So we will see!

You need to get two accounts going on. Even husband and wifes have two accounts..

And don't get the impression rock crawlers don't go fast... a lot of the crawlers here move way faster than a lot of the 'go fast' rigs do.

Except for Cal, He's always slower than everyone :P
