i took a snap shot of my rear lift blocks. do these look right? or are they some home grown setup? what should my total block height be?[IMG][/IMG]

That there is a poor mans lift kit. Make sure that thing is tight. Might torque your axle right out of those.

bradshaw106

do you have any idea how big the factory lift blocks are? my truck isn't that big

ohh man thats a ghetto lift. i would watch that rear end and axle wrap.

Richie O

Wheel hop the driveshaft right outta there.

That defiantly does not look right. I look like a piece of 2" sch 80 square tube to me maybe even a cut off from a receiver hitch (with the hole in it). Plus if I'm seeing the pic right its welded to the spring perch. The block on my W350 measures 6 1/4" from the perch on the rear to the bottom of the leaf pack.

i just measured my get-up from the leafs to the perch is 4" thats quite shorter than yours. what do you think. do the 350s have bigger blocks?

My W250 has a 6" rear block as well.

I would have to say that maybe the previous owner lowered the back or he had the rear springs re-arched and with the factory blocks it was to high so he put in the "home made" blocks.

here is what came on my 92

fist for reference size

those are huge!! anyone have a distance between spring to frame rail?
i do know that the truck has newer front springs from stanley springs. tried to email them but they never got back to me

70's thru 93 cab/chassis trucks had 6" block as pictured directly above (dually) 4 wd

70's thru 1991 W150-350 pickups had 3" block 4wd (That's why the front was higher than rear)

1992-3 W250, 350 had same 6" block as above photo. 4wd
( gives the trucks that rake effect)

Can't speak for the 2 wheelers but I believe no block.

The blocks are left and right sided as there is a slight degree of angle for pinion to t-case line up.

Good luck finding them, no aftermarket in 6", if that's what you need, only lift kits with add a blocks which are about as wrong as it gets. None available anymore from dealers, that I found.

bradshaw106

my truck sits really good. if i put the bigger blocks it definitely will sit bed high

powerrammaster

Well then, measure the distance between the perch that the block is on top of and the bottom of the lowest leaf spring and find a block that is about that height. Or better yet, change out your springs for a pair that will still give the truck the same ride height and eliminate the blocks completely, or lower the back hangers.

You are correct, sir.
