What makes the ZR2 have its 3" wider stance? Is it the length of the axles or is it the backspacing on the wheels? I have a 95 4dr LS and would like to widen the stance on it a bit.

 

What Makes a ZR2 Different From a Regular S-10 ?



If you are wondering what makes a regular S-10 a RPO ZR2, the following is the list of the factory modifications:

RPO ZR2 only full ladder-type frame with modified suspension mounting points which provide:

100mm wider track (3.9 inches wider than regular S-10)

Three-inch suspension height increase

Enhanced front (7.25" ring gear) and rear (8.5" ring gear) axles w/ 3.73:1 rear-axle ratio

Larger wheel and axle bearings

31 x 10.5R-15 LT/C black wall off-road tires (BFG A/Ts on pickups and BFG Long Trails on BlaZeR2)

46mm gas pressurized Bilstein Monotube shocks

Rear axle track bar (pickups) / rear sway bar (BlaZeR2)

Wheel flares (black on S-10 pickups and BlaZeR2 / body-color on Sonoma pickups)

33mm (early model) / 28mm (late model) front anti-sway bar

Skid plates

 

In essence its not wider axles or different backspacing. Its the package from the frame out. Including the frame mount points. They raise the truck to fit 31" tires.

If your planning on a suspension lift, buy a non ZR2 truck, why spend the money on teh factory suspension lift only to trash it for an aftermarket version.
