I purchased a kit for my Ford F150 mainly for towing, the kit was super easy to install but was a bit rough for my liking at first. The problem appeared to be that I run my truck bed loaded with a few hundred pounds most of the time so the kit was much closer to the axle and would tap the spring bumpers when I hit minor bumps. I removed the 1" spacers and things work great now, no problems and it keeps my truck more level and eliminates me having to cringe when the loaded rear end hits a dip in the road. I think the kit provides a good safety net by spreading the load onto more points of contact. Good product, but could use different spacers of a variety of thickness to personalize the kit to the load of the truck as everyone buys these to address a variety of weights and issues. 261427

Very helpful. Gave me details to make I needed to make a correct decision on what I needed for my truck suspension. I know where to go next time. Thanks.3284115

These work as advertised and do a great job of preventing the back end of the truck from dropping too low when hauling or towing. When pulling our 8000# trailer the truck ride is relatively level. I would prefer they were maybe a 1/2" to 1" shorter so the unloaded suspension would have a bit more travel. With a cap on the truck there is less than a couple of inches of travel before the stops are hit and it does make the ride more harsh. I knew this would be an issue with these. They are considerably less costly than airbags with zero maintenance concerns.611406

this is a super product. This is my 2nd set of Timbren "overload springs". my first set was on my 2002 trailblazer and this set is on my 2010 Ford F150. In both cases, it has kept my vehicle perfectly level (I measured) when I loaded up with lumber, cement, sand, or any other heavy cargo. it works just as advertised. this time I loaded it up with 500 pounds of water softener salt to give me some traction through the winter. It works a lot better than Sam because I can use it up throughout the year. 10 years ago, the installation on my trailblazer was a little difficult. This time on my F150, it was a piece of cake. However, I tried for an hour to install one without removing the wheels and couldn't do it. So I got out the floor jack and jack stands (yes, I'm a little lazy at 67), pulled the 2 back wheels, and it took 20 minutes total, including pulling the wheels and putting them back on. great product and good service from etrailer.com.109970

After over a year since installing the Timbren suspension enhancement system on my F150 4x4 I am pleased with their performance. I have a 10K LB Car Trailer that I pull. The truck sits more level now verses the rear squatting down and the front lifted. The trailer tracks very nice now, which provides an increase level of control and comfort. The only thing you need to monitor for a good ride is to make sure you don't load the back end of the truck down to the point where there is a small gap between the Timbrens and the axle. When this happens you can experience a bump in the suspension when you have rough roads. Overall I would highly recommend these.1158042

I have not installed them yet, but everyone that has a set of these timbren suspension systems swear by them. I now have a 22 ft travel trailer to tow with my F 150 and these should help with the weight on the truck. Will let you know more when they are installed. 362399

After owning the Timbren spring system for over a year I can only say that these are the "Best". We tow a fifth wheel and there is a noticeable difference with regard to height of the truck and when cornering. When not towing the truck rides as though nothing has changed and rides the same as when originally manufactured. I would highly recommend the Timbren system. Installation was extremely easy. 801633

Worked great on my f150 truck pulling a heavy loaded 24 ft enclosed car trailer full of furniture 900 miles.
Running truck without the trailer it does feel stiff on curbs and pot holes. May remove them until next heavy load. I DO HAVE SPACE BETWEEN THEM. Still touches easily.1723595

This solved the “droop” problem when pulling our Travel Trailer, but the resulting ride was VERY rough. Even without the trailer the bed bottoms out over larger bumps.3390830

Works and installs just ad advertised. Ordered on a Wednesday and arrived two days later. Great product and great service!3507798

These were super easy to install and while I have not used them yet under weight of a trailer i envision that they will preform as shown in the video.862553

Works perfectly. I have no problem towing my dump trailer or camper. Keeping the bed level while hauling makes a lot of difference.3390157

Easy install, product looked well built. We pull a 20ft stock trailer so the timbren should work great. Shipping was fast!

Installed in minutes without taking wheels off of my 2014 FX4. (Assemble rubber on bracket in vice, then install on frame). Can be done. Simple and effective. Well worth the money, couldn't imagine towing my HT fifth wheel without it.464165

Incredible !!! Great product !
Installation took about 15 minutes and the difference is just incredible, I tow a 10,000 pound trailer with an F150 and the drop on the truck was only the clearance from the Timbrens to the axle .... They handled all the load with no sag on the back of the truck! could not be happier and 100% recommend for towing hauling....
Full disclosure they will effect your normal ride when hitting large pot holes or bumps and cause a little sway but they work perfectly for what I purchased them for !! 821018

Easy to install and works great. Keeps the truck level with a load on and definitely takes out the suspension jump when there is weight on. Overall very pleased.772236

Towed a 4dr wrangler from SC to MN and the timbren bump stops worked great. 1200 miles through (including through the smokey mountains) with a smooth ride the whole way. Easy install. Highly recommend.3319261

Product works great and installation was easy as described . Has a smooth ride under a heavy load. I was really surprised at how well this product worked. I would recommend this product to anyone.3563963

They work as advertised. I added a slide in camper to my 1/2 ton Ford and the extra weight is carried well.3592016

Had doubts that I could pull installation off in my driveway. I'm 66 years old and have problems getting up when on the ground. Installing this product was simple and had to take it back apart to take the spacer out for the correct 1 inch gap.3630397

I already had the Roadmaster Active Suspension on my F-150, but the steering still got squirrely if I was pulling my dump trailer with more than 1.5 tons or my equipment trailer with my tractor. After installing this I feel like my only limitations are my brakes and engine. If you are on the fence just do it, it works! Install was super easy too, even with the RAS on there, maybe 30 minutes. Wish I'd done this years ago.3548519
