lowering a 68 3/4 ton!

[vegard]

Hi!
Someone have any experience lowering a 68 GMC 3/4 ton truck????
Can`t find any parts on the big web... or what parts from other car`s could work?

Take a look at early classic enterprise. I just saw spindles on there I think.

[low'n slow]

GMC Pauls sells a drop spindle for 73 and up. I believe you have to change the ball joints to use them.

are you wanting the truck to remain a 3/4 ton? Or are you wanting to convert it to 5 or 6 lug wheels

the spindles from ECE will work. You can also cut a coil from your springs, or install 1/2 ton lowering springs pre-made

and in the back, you would lower it like any other leaf spring truck - different shackles and hangers, or a flip kit -- if you wanted it low enough to justify a flip kit, i would think you might need 1/2 ton springs, or you could take a couple of leafs out of your existing spring pack

Thanx for the feedback. I`d like to keep it a 3/4 ton but convert the front breaks to disc.
I am a newbi on this things so all advises are welcom

I'm pretty sure you can find the front end off a 72, they came with disc brakes. On mine I added 2.5 drop coils for a c10 and found a tire shop that would mount street tires on 8 lugs rims. On the rear I added 2' drop shackles, removed half the stack and dearched the springs 2", which over all from the factory height it lowered for front 4" and the back 7".

I have 2" beltec (for a 1/2 ton 6 cyl) drop springs in the front of mine and took two leafs out of the rear packs. I have tried a few different way's of lowering it. I first cut the stock springs and mono leafed the rear, I do not reccomend this. It was the perfect height, but rode very bad. I then put the drop springs in the front and added some of the leafs, it looks o.k. but is too high for me. I use the truck to haul myself to work, and to take the atv's to the dunes. When I loaded the big atv in the back (sportsman 500) it really dropped the truck and road like crap. So now I am going to make some shackles for the rear and put the other leafs back in. I am also going to cut the front drop springs (only until I can afford air ride springs for the front). The picture is when I cut the stock springs. I do not have any current one's with the drop springs and the new 265 60 r16 BFG's yet.

GMC Pauls has 3/4 ton drop coils, front and rear: http://www.gmcpaulstruckparts.com/67-72_d&s.htm
If you have leaf springs in the back, there are drop shackles and leafs available on the net, or you could do an axle flip...

Thanx for all good advices
I think i am going to swop the front drum brakes and suspension for a 72. That way i will keep the 8 lug and get improved braking with the disc brakes. That way it probably will be easy to lower the truck???
