Just resently put f-150 key on a tahoe gave it up to 3" of front end lift. Since the zr2 is a 1/2 ton will it fit my zr2 blazer?

 

You dont wanna try to push a s-series over 1.5 inches. Unlike the fullsizes they are already about maxed out from the factory.

 

No it won't work. The zr2 keys and torsion bars will fit a standard s series. The fullsize bars and keys are too big.

X2 on the 1.5 inch rule. Some people go further and are fine, some destroy balljoints and shred cv boots just by thinking about cranking thier bars. But in general it's accepted with some degree of extra wear, that 1.5 inch is the limit unless you enjoy replacing your front end 1-2 a year.

 

just use a 19mm socket

x3 dont go over 1.5"-2.0" max
