Has anyone had any experience with Timbren or Sumo Springs on their tow vehicle? They replace the factory bump stops and are supposed to prevent rear end “sag“.
Any advice based on experience would be welcome.
I have Timbrens installed on my GMC 2500. I installed them to level the ride when we use our Hallmark truck camper. Our set up doesn't allow us to tow the airstream with the Hallmark loaded, which we never intended anyway. I did find that when towing the airstream I needed to adjust the hensley hitch so that the timbrens are engaged but not carrying all the weight. Too much weight seems to make the ride bouncy. Easy adjustment with the hensley. I also changed the stock shocks to bilsteins and with the combination I am very happy with the setup. No proposing and a smooth ride.
Had Sumo Springs installed on my 2019 Ram 1500. 1500# models. Took the slight sag away and just slightly better hitting bumps and dips. Same unloaded. Towing a 2019 25 Globetrotter.
We had the Timbrens on our Dodge 1500....did help with sag but we found they made the ride too stiff.....took them off and installed airbags....for us was much better ride when towing....
That said we sold the dodge and now own a f250 super duty
Sumos were tremendous for us twice. The first use was on our Navion Class C - greatly reduced the rolling motion every time we went over a curb. And they smoothed out the ride on our F250 so that it didn't feel like we were going airborne every time we hit a washboard road.
Easy installation and a great investment in our ride.
