1999-2018 Silverado Sierra Shock Extender For 5/8,6/9, 6/10,6/11 Drop Kits

Nnbs Shock Extenders

Definitely made a huge difference . No more bottoming out , much stiffer ride . Very easy to install , yes I recommend !

You guys are the only ones that offered shock extenders for a 11 inch drop on my 06 crew cab GMC pickup deeply appreciate it the right geometry makes all the world difference of ride quality you guys are the s*** you all have a great day...:+1::+1::+1::sunglasses:

Awesome Product

Bought these for my 14 Sierra Slt. Rear driver shock was bottoming out and passenger side didn't have much travel so I ordered both. They came in fast and are great quality took about a hr to put on. Truck rides like a dream again.
