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.

    • Less hassle than airbags
2nd set on the 2nd truck I have used them, takes the squat out and helps smooth the ride when towing, will et them again when I upgrade trucks!

    • 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

    • Excellent product, Highly recomend.
Seen videos of these so I recommend. Purchased a set for our 3/4 ton silverado and works very well when hitting those bumpes on the road while pulling our 38ft camper. Easy to install, anyone can do it, very simple. Super high quality from what I have seen with the cheaper brands.

    • Great product, level ride, easy install
Review Image by 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

    • Well worth the money!
I do NOT like how they fasten to the vehicle. They don't sit into the base properly and I haul every day. I thought from what the instructions said weight pressing down on them would make them seat but so far it hasn't happened. But I LOVE the improved stability to the truck when loaded.

    • 2014 Chevy 2500HD
Have these on my 2014 Chevy 2500hd and they work great. I pull a 30' gooseneck trailer and they support very well. Worth the money instead of going with an airbag set up
