The new McGaughys 34170-2 drop kit for your 2014-2016 GMC Sierra 1500 All Cabs 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 2" to 5" or anywhere in between, and drops the rear from 5", 6" or 7". This McGaughys drop kit comes with everything needed to get the job done right! 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.

  • 2014, 2015, 2016 GMC Sierra 1500 2wd Extended Cab
  • 2014, 2015, 2016 GMC Sierra 1500 2wd Double Cab
  • 2014, 2015, 2016 GMC Sierra 1500 2wd Crew Cab
  • 2014, 2015, 2016 GMC Sierra 1500 2wd Quad Cab


  • Will fit 4wd models with Steel Upper Control Arms 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, however, 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.

  1. get what you pay for, great ride!

    Had this 4/7 on my 2014 rcsb, and it rode great and obviously looked great! Less sidewall on tires will have a part in your ride quality, which at first I was on stocks then switched to a 22/24 combo. All in all great kit, wouldn't even consider any other brand.

    Had this kit installed on my 2015 silverado crew cab couldn't be any happier with the stance. We went with a 5/6 drop truck looks awesome and it rides better then stock.

    We did the 34170 kit on a customers truck for a recent Street Trucks magazine tech article. The kit worked out perfectly for us. We also elected to run the 34049 rear air helper kit on the truck as well. What we liked most about this McGaughys kit is it allowed us the ability to fine tune the lowering amount in the front with the adjustable struts. The customer loved it, shot well for the magazine and was super straight forward! Get one, you'll love it!
