Timbren SES unit in TV (coil spring system).

How to install Timbren SES units in a Tow Vehicle (that uses coil springs).

If wondering, Tinbren SES units are like air bags without pressurized air inside them. Thus, no worry about air leaks and best of all, they are a no fuss "install it and leave it" suspension upgrade. For more details, surf:


Here's how I installed Timbren SES units within my wife's mini-van (that uses coil springs).

Factory "bottom out" stops:

Now, we can have more rear cargo and/or more trailer tonque weight without our mini-van's rear being compressed too much. Much less rear sag then factory build. If wondering, our future vehicle will use Timbren SES units as well.

Hope this helps others...

This summer I am going to install either Timbrens or Firestone air bags. I really havn't decided which one to get. Our trailer is heavy and my Rhino is heavier and I want to take both with me.
2011 Eagle 330RLTS with just about every option.
2017 Silverado 1500 4x4 5.3 with tow package. (no, we don't tow the Jayco with it.)
2018 Surveyor 265RLDS well equipped.

Timbrens and air bags are not really alike at all... they serve the same function, but in two different ways. Also, air bags are fully adjustable for different loads, where as Timbrens are not.

I have air bags on my F250 and Timbrens on my wife's 4Runner. The biggest load we put on the 4Runner is the boat, and it is consistent, thus no need for adjusting. I like the air bags on my truck because I haul lots of different things with it and can adjust as necessary.

Thought for sure I wrote "Timbren SES units are like air bags without pressurized air inside them". Therefore, they are not 100% alike. My buddy across the road has Timrens SES within his Pickup - for his 5er. No "airing up" and "airing down" - each time loading is changed. And best of all, NO air to worry about. Which means no worry about air leaks. He likes Timbrens and so do I. Especially for an "install it and leave it" solution. Something that air bags cannot do.
