1995 Gmc Sonoma Help

I Have A 1995 Gmc Sonoma 4x4. It Has A Stock Suspension. I Want To Get The Height That The Zr2 Has I Heard From A Mechaninc That The Only Difference Is Toursin Bars Are Lifted And Add A Leaf. He Said Shackles And The Same Torshin Bar Lift Would Be The Same Clearance And I Can Run 31' 10.50`s Is He Wrong Should I Even Do That I Dont Want A Lift Kit They All Require Welding. Please Give Me Any Information To Give My Truck A Taller Stance I Only Have 108,000 On It But Its Not New Enough For A Big Investment Like Pro Lift I Only Need A Little More Lift For The Trails Around Hear And Snow Berms.
