how much lift needed? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Burlinator · 06-29-2001, 03:50 PM

my cousin has a 73 3/4t long fleet and he just picked up a set of 38/15.5-16.5 Super Swamper's for his truck right now he is running 33/12.50 BFG"S with unknown lift installed by dealer back in 73. My ? is how much of a lift is he gonna need to run these bad boys? and what combo of steering linkage will work best dropped pitman arm? steering arm block? dropped draglink? or will he need to use all three of these? thx in advance
P.S. got any pics of this lift tire combo?

Probably the easiest would be a 6" susp. lift, and a 2" body lift. Or, a 6" susp. lift and some fender trimming.
Those are wide tires. I hope you have wheels with reasonable backspacing so they won't hit when you turn.
For steering, if you have a 6" susp. lift you'd need a 4" steering arm and that would probably be fine. ALso great would be a 2" pitman arm.
First thing to buy though is a steering box brace. Should be considered mandatory, it's about $95 and it's a bolt-on.

I just reread your post and you said steering arm block. The 73 k20 lwb will have a d44 8-lug up front. It takes a replacement steering arm, not a steering block. The k30 has a dana60 that takes a steering arm block, if needed.

thx for the response guys
hey mike will stock wheels work out with this set-up? and for a lift as much as 6" or 8" will spring pads need to moved for correct pinion angle? or different driveshafts we thinkin on how we can drop the t-case and engine down a bit ever seen any kits for this kind of mod?

yeah imp I don't like body lifts either!
