Product Description

Timbren Suspension Kits (SES Kits) are designed to enhance the suspension of your vehicle. Easiest to use: Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions. Easiest to maintain: There are no airlines or fittings to allow leaks. Simply bolt the kit on and you are set for a lifetime of trouble free suspension.Easiest to install: There are no holes to drill, no airlines to route and SES Kits can be installed in a matter of minutes using basic hand tools. The softer ride quality of todays trucks and the mediocre suspensions found on most trailers can cause excessive trailer sway, instability and suspension settling.Timbrens high performance suspension packages will ensure added safety and peace of mind.

    I received these today and installed them in about 30 minutes. Most of that time was taken in lifting each side of the truck. I would say it was a very easy installation. I went for a test drive and on smooth to mostly smooth roads there was no degradation in the ride quality; however, the second I went over a speed bump or deeper gutter or something like that you could tell the difference - they hit hard (as expected). I pull a 33 ft/7500 lb (fully loaded) travel trailer several times a year and this year also purchased a 2020 GMC Sierra 1500 SLT w/ Max Trailering package (nht). This truck has plenty of power for the trailer and all gear but for some reason - even after fine tuning a new equalizer brand WDH - it squats a bit with the load of the full trailer (no squat with empty trailer). I've taken all weights and am well within all load limits (payload, max tongue weight, GVWRs, GCVWR, max trailer weight, etc). I'm hoping these Timbrens will solve this problem. I'll find out in a couple of days as we are about to go out again this weekend. Crossing my fingers!

    Reviewed in the United States on June 4, 2019
    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..

    Reviewed in Canada on November 3, 2021
    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.
