McGaughys has released a game changer to drop your Chevy Silverado or GMC Sierra. This all new lowering kit fits your new body style (2007-2013) GMC Sierra 1500 quad cab, crew cab, four door truck. The new McGaughys 34070 lowering kit (drop kit) includes our all new Pro Performance adjustable drop struts which allow you to choose any drop in increments of just 1/2" for the perfect stance. No more agonizing over which kit to purchase. This drop kit does it all. Adjusts the front from 3" to 5" or anywhere in between and drops the rear from 4" to 7". Below you will find all of the specifics on this lowering kit- 

This McGaughys Drop Kit Includes-

  • Front 2" drop spindles (the only brand that works!)
  • Front adjustable premium strut assemblies
  • Rear Flip Kit
  • Rear Lift Hangers
  • Rear Pro Performance premium shocks
  • Rear Shock Extenders (allows for full shock travel and correct geometry)

Our Recommendations-

  • 3/5" drop clears factory tire diameter and does not need c-notch or air helper kit in most cases
  • 4/6" drop clears factory tire diameter (May require minor trimming of inner fender liner) C-notch non needed in most cases. Air helper kit is recommended if towing or loading truck bed often.
  • 4/7" -5/7" May require a smaller over all diameter tire or more trimming to inner fender linners. C-Notch is HIGHLY recommended and an airhelper kit would be a great addition if towing or loading the truck bed.


  • This kit WILL work on 4wd model trucks as well, but should not be ran lower than 2" of drop in front. McGaughys recommends 2" of drop, but we have had good luck with customers being able to run 3"/5" on the 4wd trucks, but this would be lowered beyond McGaughys recomendations and at your own risk, as McGaughys will not warranty 4wd issues when lowering more than the recomended 2" in the front.
