Re: ZR2 lift and fender flares
I'll begin by saying NICE BLAZER [img]/wwwthreads_images/icons/smile.gif[/img]!
A ZR2 has 3 inches (75mm) of suspension lift, and they sit 4 inches (100mm) wider than a stock S-10. I think they accomplish the lift in the front with longer upper and lower control arms and jacked up torsion bars. I think the rear gets its lift from leaf springs with more arc than a stock S-10, but it could be from lowered spring brackets on the frame too, as they look to sit lower than necessary on my truck.
The front wheel wells are larger on a ZR2 than on a stock S-10. You could have the front fenders trimmed, but then you may have problems fitting inner fenders. The rear shouldn't be a problem as it would be easier to trim to the proper size. ZR2's come stock with 31x10.50xR15 BFGoodrich All-Terrain tires, but I fit 32x11.50xR15 Mud-Terrains on my ZR2 with only a little bit of tire rub in the fenders while cornering and hitting a large bump at the same time.
I'm sorry to say, but you can't just throw on a 3" suspension lift and call it a ZR2. ZR2's have narrowed full-size GM truck 10 bolt rear axles that are still something like 3 or 4 inches wider than a stock S-10 axle. I'm not sure what they did to the front axle, but I think it's wider than a stock S-10 4x4, too. All ZR2's come with 3.73 gears - and you'll need them if you will be running anything larger than about 30" tires.
Hope this helped.
