SUBURBAN vs. FULLSIZE DIFFERANCE?

What is the differance from suburban suspinsion and reg. chevy fullsize?Will a reg. chevy kit 5 -7 work ? Not ready to bag tell its paid off!

Does any one make a 3" drop spindal?

THE BIGGEST DIFF...IS THE REAR FRAME AREA SUBURBAN IS NOT STRIGHT LIKE A FULLSIZE FRAME.....I PUT SPINDLES AND SPRINGS OUT OF 1500 TRUCK INTO MY 1500 SUBURBAN.....NOW I GOT BAGS!

So the front is the same ?

djm makes a 3" drop spindles. I think the only diff is the rotors , there are 2 sizes .

NO ONE MAKES A 3 INCH SPINDLE FOR THAT YEAR SUBURBAN. THE TRUCK AND SUB ARE BASICALLY THE SAME SUSPENSION WISE. EXCEPT, AS STATED ABOVE, THE REAR FRAME SECTIONS. SO YOUR PRE-FABED C-NOTCH'S ARNT INTERCHANGABLE.

what year ? because I've got and 87 sub with a djm 3" spindle .

In 92 is when they changed the bodys on the suburban. So if you have a 91 or lower then yes they make a 3" spindle. If its a 92 or newer then its a 2" spindle. Either way the truck spindles will work. On the 91 and lowers though the there are 2 different spindles one for the 1" thick rotors and one for the 1 1/4" thick rotors. As for the rear, all suburbans are different from the trucks.
