I was just kidding when I said "I've only got a stock S-10 ZR2 but then thats better than most 4x4's of the showroom floor", but I am quite happy with the stock options:
**The RPO ZR2 has a full ladder-type frame with modified suspension mounting points which provide 100mm wider track (3.9 inches wider than the regular S-10/Sonoma) and a three-inch suspension height increase.
**Larger wheel and axle bearings.
**Enhanced front (7.25" ring gear) and rear (8.5" ring gear) axles with 3.73:1 rear-axle ratio.
**31" x 10.5" R-15 LT/C black wall off-road tires (BFG A/Ts on pickups and BFG Long Trails on BlaZeR2).
**33mm (early model) and 28mm (late model) front anti-sway bar.
**46mm gas pressurized Bilstein Monotube shocks.
**Wheel flares (black on Chevy and body-color on Sonoma).
**Skid Plates
.... although this winter I'm going to install a 5" suspension lift and a 2" body lift and upgrade the tires to 33" or 34" (depends on how much trimming I have to do to get 34's to work without rubbing since the wheel wells are so darn small)
