This SES Suspension Upgrade fits the front or rear suspensions. Timbren engineered their hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag. Whether you’re pulling a trailer or carrying a heavy load in the bed of your truck, Tiimbren's hollow rubber springs adjust automatically to keep the vehicle level at all times.
This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality – loaded or unloaded. (There should be a 1/2” to 1-1/2” gap between rubber spring and axle to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.
These seem like the best product if you always have a similar weight load in the truck, as once they are loaded the ride great and no maintenance. I was hoping there would be more space between the frame and timbren to allow the truck to ride better when it was unloaded. With airbags at about the same price and allowing 5 psi pressures now, I believe they are the better option for preserving ride quality if you often have the truck unloaded. Just my two cents.

3.0Works as advertised unlike the retailer
Works like advertised. Not as good as airbags. 4wheel parts sucks at informing customers about delays. Website said it would arrive at the store in 3-5 days, a month goes by and haven’t heard a thing. If you want to buy these order off of Amazon. 4 wheel parts will never get another dollar from me.

Beefy and a great addition to the Tundra. Looking forward to hitting the trails for true test
5.0No more SAG!
I bought this bump stop for my 2016 Tundra 5.7 trd to help with sagging while pulling a 26' travel trailer. Works great in conjunction wdh and installation took about an hour(easiest if you remove tires). Timbren is twice as big and strong as OEM part. Must have...very happy with the purchase...price was also competitive.
