Suspension Enhancement System – Rear Kit for 1999-2019 Chevy Silverado 1500 & 1999-2019 GMC Sierra 1500 by Timbren (GMRCK15S)

Arrived quick! Install easy. Performance flawless. A must have for camper towing!

Total time to install was less than 30 min from the time I jacked up the truck to removing the jack. Easy install that makes a major difference with hauling any weight in the truck. No noticeable difference in ride quality until I load up the truck, then the truck handles much better with more stability in turns than with the stock bumpers. Good upgrade for the money spent.

Easy install. The day before they came i sprayed some pb blaster in the opening. 10mm socket for the old ones and 17mm for the timbren. I used hand tools and found its easier to take a tire off by doing that you dont have to lay on the ground. Took maybe 25min . Towing and 31 foot TT and dont like the whoops in the road. Update put about 300mi hauling the tt bosters & work great definitely a little stiffer while under load. Only time I feel them without load are speed bombs of shitty roads.. body real is much less while I lift alot.. If you have the money for high end air bags thats a better choice. For me, these are install and forget ZERO Maintenance..

However, easy to install and well made. Probably worth the money. Time will tell. Only dislike is the thump when not loaded and hitting bumps. Spaced at 1-1/2". All in all, I do like the performance when loaded and can get used to thump unloaded.

I want to thank the seller for the speedy shipping. The seller offers free shipping and I got the Timbren kit in 2 days. Faster than Amazon prime shipping. I Had a timbren kit on my Nissan Titan and loved it. I moved cross country with the bed of my truck stuffed from the floor to the cap. There was absolutely no room left in my truck. Even my back seat was stuffed. Plus I had a dirt bike carrier for my trailer hitch that went across the back of the truck with my 450LBS dual sport motorcycle on it. There was absolutely no way I could of made the trip without the timbren kit. I have since sold the truck and got a silverado. This kit I just bought is for that truck. I don't necessarily need it right now, but when I do, I know it will be there. allowing my truck to handle a load without sagging. Plus making it a more stable and safe ride. Very satisfied with product and very satisfied with seller.

Have had 2 trips pulling my RV with thses added. The Squat and stability is so much metter. I have started telling people they need these. Easy to install and only works when you are Loaded is a win for me.

First ordered parts and had to wait a week longer then expected , then get notice from carrier stateing order being held for me to come pickup at carrier fascility , instead of shipping to my home . Then when installing bolts give u lowest grade of bolts they can instead of 2 grade 8 bolts . And go to put them on and while tightening them down break in half cause to wimpy , I mean if I pay $ xxx.xx for something at least give quality parts to use instead of junk . Very unhappy and dissatisfied customer

Was easy install on my 2002 Silverado z71 1500. Has about 2 inches of space before touching so ride quality isn’t effected unloaded. Fast delivery. 5 stars

Installed on my 2017 Sierra 1500. Got them to help handle hauling my sled around in the box as well as towing my enclosed trailer and travel trailer. Needed the optional spacer kit as I have a 2.25 readylift block in the rear. Ended up with about 1.4 inch gap unloaded(recommended 0.5 to 1.5 gap). Used the 1 inch spacer included with that spacer kit. Rides like stock when empty and handles fantastic when loaded. More stable in the corners and confidence inspiring over bumps. Pretty much feels like a 2500 when loaded. Well worth the money in my opinion.

Install would’ve been super easy if the stock bolts weren’t rusted af. But it was worth every minute of struggle. These are great in my 2016 Sierra 1500. It’s only been a few days so I can’t speak for the longevity of the product, but they seem very solid. 10/10 would buy again.

Amazing put these on my stock serria 1500 and it's night and day the difference the truck only squats an inch or so when towing a 7000lbs dump trailer.Instalation was super easy just jack truck up as high as you can until wheels start to lift. Grab 10mm socket and extension peice and remove the stock bump stops. Have a breaker bar ready mine were rusted on pretty bad (northern Canada) and install the product no more then 15min install easy do it your self. I've had airbags in the past and I prefer these

Installé sur mon GMC Sierra Elevation 2019 avec cabine LEER, je traine un trailer fermé 12 pieds avec environ 1200lbs de charge. Lorsque le trailer n'est pas là, je sens les Timbrens s'accotter sur l'essieux quand il y a des trous ou bonnes bosses, pour vivre au Québec, c'est chose fréquente. Avec le trailer, ils sont accottés sur l'essieux et la suspension devient maintenant les Timbrens. Ce n'est pas une suspension à l'air donc porte plus dur, mais se conduit mieux. On sens vraiment plus les bosses avec le trailer, probablement car il n'est pas assez chargé pesant. Après une semaine d'utilisation je compte bien les laisser en place quand même.

I haul a water tank in my half ton and with these it makes all the difference . Once loaded up they handle well , look way better don’t sag down like the factory ones . With weight on them they handle very good . Very pleased .
