add T keys and coil spacer to rancho 4 inch???
 

I have a 2003 Hummer with a 4 inch rancho lift already on it when I got it I am on 37s now and thinking of going a little bigger I want to know what yall think about putting a set of torsion keys and rear coil spacers on top of the 4 inch to go about another 2 inches.. What about drive shaft lengths? alignment? keeping rear spacers in? Ride? I plan on upgrading shocks at same time so I will just go with a shock for a 6 inch lift... THANKS!!

Dude, can you post pictures of your hummer on a side view angle? Just wanna see how high and thick a 37" is. Thanks

anybody else got any input on my questions

just up the tire size a few inches

Yeah I plan on going bigger on tires but I have never been one to shove the biggest tire under a small lift.. I like the look of having fender room and no rub..

that cool i haven't lifted yet but i am running 37's no rub yet and i love the ride. how well do you like the ride on that lift?

your half shafts up front will be maxed out and vibrate badly. There is enough adjustment up front on the rancho kit to max out the angles as is. So adding more height to this kit will cause you some problems for sure. I have 1st hand experience with this idea. i too wanted more out of the Racnho kit when I 1st got mine a few years back (previous truck) and learned immediately the front end could not be brought up too high. Adding spacers would have done the same thing.

You can fit 38's on this lift and still have room to flex/ offroad..depending on your wheel specs. 17 x 9 4.75 bs will allow for 38" BFG MT's. 40's will be too big to wheel without some rub, but fine for street use if you don;t venture out of the parking lots.

...hope that helps some.
