Suspension Enhancement System

Held up well to the weight of this load of sand. Under this load they are a little bouncy. Would definitely recommend them for people that occasionally need to move some landscape supplies or tow a heavy trailer short distance. Keep in mind payload limitations and assume your own risk.

Amazon says, “This does not fit your 2021 Ford F-150.” They are wrong. Not only does it fit, but it is so simple to install, I installed, removed, reinstalled and desired to take a short trip to see if I will reinstall the 1” spacers that come with the kit after I tow my trailer another few hundred miles. These are great! I highly recommend anyone who tows or carries a load in their truck to install these.*NOTE: The installation does not give you more towing capacity! Follow your manufacturers guild lines when towing or carrying any kind of loads.

Went the cheaper route than airbags. And for me it worked well. Hold great when camper is on them, and good when off. Much better and a pretty good value. And they were recommended to me by someone so that is now 2 recommendations in one review.

I have several buddies who recommended these due to the ease of install and how well they work towing. The issue is they all installed them on 3/4 and 1 ton trucks. They have no impact on stock empty ride. I installed these on my 2015 F-150 ecoboost and even with maximum space between the timbren rubber spring and the axle I am still slamming and bottoming out just daily driving to work. I cannot ride around town bottoming out just to have a little better towing ability 8% of the time when I hook to a trailer. I returned them (which the seller accepted thankfully) and purchased air bags.****NOTE: I am giving 3 stars because the product is a solid product and the seller is a great seller. The issue is it is not supposed to effect stock/empty/unloaded driving and it does ON AN F-150. I've used these on an F-250 and they worked as intended****

Easy to install. Only down side was that one of the nuts was welded off center of the hole, so the bolt wouldn’t screw in it. Called timbren and they sent me a replacement part.

I had to have these removed from my vehicle as they created a driving and safety hazard when I was tolling. It created such a stiff ride that the trailer began to see saw while driving down the road. The trailer was properly loaded and attach to the truck. Never had this type of issue in the past. But this product created such a stiff ride for the rear axle it actually caused the trailer the and become unstable... It created a major driving hazard and unsafe conditions. This product should not be on the market... I requested a refund we will see how the process goes.

Good when towing makes a rougher ride when empty, but that is expected.

Performance

Works well when loaded but very rough when unloaded, there should be more of a gap between the rubber and bump stops.

Absolutely crap!Install is not easy, deep sockets need to be perfectly long enough to get bolt inside the rubber stopper and the bolt slips down inside the deep socket. Says it’s a five min job maybe it is if you had the right sockets. Now I have to drive an hour or two to find the right sockets attachments to fit this rubbish.Maybe if someone who was in the design team added a inch of rubber inside and made the bolt longer it might be a five minute install.Think before you start designing and wasting people’s money and time!Buy at your own risk. Not easy to install unless you every socket know to man kind.Poor
