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.

    • Great product, level ride, easy install
Review Image by daniel eslinger daniel eslinger
Very happy with these Timbren SES bump stop replacements. 3/4 ton pickup sits more level loaded. I do have the front keys on my Silverado turned up which makes any sag in the rear look even worse. Doesn't make a loaded drive any rougher and they sit about 1.5" off the axel when empty so no change to empty ride. Easy 10 minute install. ... show more

    • Support Easy to install and Effective in eliminating bounce
Does a great job at eliminating sagging and chucking when towing our trailer. Super easy to install. Took maybe 15 minutes and most of the time was getting the jack setup to raise the rear of the truck via the trailer hitch receiver. Lined the timbren up with the bump stop hole, placed scarp piece of 2X4 on top of the axel and lowered the jack until the timbren popped itself in place. Repeated on the other side and everything was installed. Super impressed towing the trailer that we did not have the excessive bouncing on the highway. The timbren did not change the empty weight of the vehicle. Much easier to use and install then airbags and does just as good of job. Highly recommend these if you are having issues with chucking and excessive bounce while towing a trailer. ... show more

    • Work great
I had two inches of squat when I towed my fifth wheel. Installed these and they got me to almost level and still have a good smooth ride. About five minutes each to install. 2024 Silverado 3500 single rear wheel towing 14,000 pound fifth wheel with 3,200 pound pin weight.

    • Reduce Sag, Better towing
Review Image by stephanie sandberg stephanie sandberg
Added these to our 2024 2500HD Z71 Custom for improved towing and reducing the sag in the rear end. Doesn’t change unloaded ride, but improves towing. The progressive spring helps reduce chucking of our travel trailer, and reduces sag so it’s easier to set up for level towing setup. Easy to install. Literally took less than 10 minutes Add dawn dish soap to the lip of the spring. Used a floor Jack to lift the rear at the hitch to Jack the rear just enough to get a scrap piece of 2x4 under the spring placed at the cup it needs to get into. Drop the Jack so the spring is pushed into the cup using the weight of the truck, check to make sure it’s fully seated. Repeat the other side. ... show more

    • Timbren SES
Pro's : Easy installation, Better feel and handling while towing. Con : The product was received with a lot of grit like granules on it, which made me believe that this item had been returned by someone.

Review Image by Ashleigh Ashleigh
Perfect for heavy-duty hauling on my dually truck. Took about less than an hour including prep and installation on both sides. Immediately noticed a difference in smoothness of ride. Kicking myself for not purchasing sooner- as my family and I frequently haul our 43' camper long distances and I haul heavy equipment and debris for work. (Picture is during installation- wood needed as part of placing on truck) ... show more

    • Great Product, Easy to Install
Very easy to install. All you need is a floor jack, a big flat tip screwdriver and a piece of 2X4 about 4 inches long. Working gloves optional if you do not want to get dirty or save yout knuckles. All you need to do is pry the olderones out, put some soap on the Timbren and slide in the cup. Place the 2x4 between the axle and the Timbren and lower the vehicle. The weight will sit the Timbren in place. As far ride. None adjustable, does help a lot in stability and ride. Perhaps the adjustability of air bags is better but for $250ish an a few min DYI is a bargain. If you want to improve your ride, this is the best choice for the money. ... show more
