In what specific ways?, and do they all use the same basic suspension set up since 87 or am i going to have to modify it?

 

The V8 springs are heavier to compensate for the extra weight of the motor and some for the heavier transmissions behind them.

Every spring has a compression rate, ie it will compress so far under a certain load. If you put a v8 on a v6 spring its going to compress it farther than it was designed to go. You may bottom out your shocks, but I would be more worried about ground clearance unless you want to lower your truck. In which case.....you should be fine.

 

Yes but i would need the V8 springs because i dont want the front end sitting lower actually i want to raise it higher than what it is now because its sagging in the front compared to the back by about 2 inches, But will i also need V8 shocks?, and Will the handaling be the same?

 

My guess it would ride the same with a v6 any v6 springs as a v8 with v8 springs. You can lift it by adding in some coil spacers. Check the FAQ2 for a link. My guess V8 shocks are the same as V6. Check www.autozone.com and see if the part numbers are the same. If they are not the same your v6 ones will work but may not last as long or they may not help on bumps.
