Big or Bigger, You Decide
If you own an '07 Chevy/GMC 2WD pickup or SUV and want more stature, then check out one of Superlift's kits. For mild leveling, the company offers a 2-1/2-inch front kit that uses either preload rings under the factory coils or replacement high-pressure-gas Superlift monotube shocks with the factory coils. For more elevation, you can pick up the 6-inch kit that uses high-clearance, one-piece lower control-arm crossmembers, combined with replacement cast ductile iron knuckles. Rear lift options are 5-inch tapered blocks or Superide replacement springs.
