Another S10 Pack thread.... kinda

Im ditchin the rear block lift cuz its dumb. It has held up but the ride is stiff and blocks suck. Currently its stock packs sittin on a block for my lift Im gonna get a hold of some ZR2 Packs and do the S10-XJ-Combo lift for around 4.5-5". Im cool with the back bein up a little higher its no biggie. But just so I have everything right, I need:

S10 Packs
U-Bolts
Center Pin (maybe)
Leaf Clamps (maybe)

Thats all I need in terms of parts, correct? I dunno if I am gonna do the enamel painting thing, but Im leanin towards yes.

My main question however, is for those who have the S10 Packs mod. How is ride quality compared to stock? And anyone know the life expectancy on them?

the center pin and the leaf clamps are a most likely, the u-bolts you should, but you might be able to get away with reusing them.

You will also need a extended rear break hose. The Bendix part number for that is 77032 . It was only 16 or 17 bucks, and its 4 inches longer than the stock one.

The ZR2 ride will be firmer than stock (4wd lift package).

The Z85 ride will alos be firmer, but not as firm as the Zr2 (4wd package).

The Z83 will be firmer than stock, but less firm than the Z85 (2wd package).

I'm about 7" in the rear and the ride is a LOT firmer. Going to pull a leaf or two out of mine and lower it down to around 5.5-6" and add shackles and .5" ubolt eliminators and get a much better ride and flex.

I agree that blocks suck, but how do you figure they're stiffer than just the stock packs? Obviously, no one can dictate what your subjective view of them is or should be, and it's good you're going a different route, but I've read this opinion online before and had to ask about it.

because I have a stock XJ next to it, rancho shocks.

Then 7" of lift on the other XJ on trailmaster shocks.

I can stand on the back bumper of the stock, jump up and down and damned near bottom them out (stock packs) with me about 210lbs and jumping pretty hard.

I can stand on the back bumper of the lifted XJ and jump up and down in the same manner and it barely moves 2-3" or so max. They're VERY stiff if you use the whole pack, which is why I said I was switching the pack around. Going to use the 4.5" main leaf I have, with 2 S10 leafs and the overload leaf, then with 1" shackles and .5" ubolt eliminators I should sit at the same height and not be quite as stiff as now with a lot more flex.

Here's another example. When going over large speed bumps my rear end no longer absorbs the speedbump over about 5mph. It falls off and bounces. I know this cause if I keep my foot on the gas I get a blip in the speedy pedal when the tire loses traction.

You are right, lift blocks do nothing to add to the stiffness of suspention, only leaves can do that. The biggest problem with running blocks is axle wrap. Another argument against running lift blocks is the possibility of failure. Considering the size and the power (or lack there of) of most XJ's, the odds of lift block failure is slim to none.

As to answer the original question, the ride will be a little stiffer than stock, as for the life expectancy, I'll let you know when mine start to sag.

Then why do stock packs with no blocks feel smooth, but a block lift feels like your riding on, well... blocks

Plus havin the S10 pack instead of a block will give me more flex

The stiffness of your ride is mostly due to the incorrect suspension geometry of your front suspension. If you are looking to correct this either use drop brackets or long arms. Either way, it isn't going to be easy (or cheap) to get you stock ride quality back.

I ran blocks for a while as an interim to fixing up some decent leaf packs. First time the block wrapped the spring perch around the axle (1.5" blocks).

Second time it spit them out (1" block).

That was in a span of about 8 months.

depends on how you build them. I would recommend probably the two S10 main leafs, overload leaf and no bigger than 1" shackles to get around 5-6" of lift. That should net you some decent flex.

Wrapped the spring perch around the axle? You did have the spring perches welded on, right? As for spitting out the lift block, sounds like a problem with not having the u-bolts tight enough, either that or your blocks didn't have any sort of centering pin.

eh... stock spring perches... they do fine on a normal leaf setup with no blocks. Put blocks in there and they don't hold up. They were the standard steel blocks like everyone else has. Hole in it and plug on the other end or whatever..
