Timbrens Off road bump stop

I use my Tacoma on washed out gravel roads quite a bit as well as haul a a single axle with maybe 300-400lbs tongue weight at times or have 400-600lbs in the bed at times. The rear drops quite a bit, usually over 2". The truck is a 23' Sport with the 4 leaf rear. I talked to ETrailer and Timbren and the I ordered the TABSOSR offroad stops from ETrailer. I'm now second guessing them. Timbren lists them at 2,000lbs at 50% compression and 4,800lbs at Max compression. Timbren customer service said, yes, they will help a little with extra weight. ETrailer said they are not load bearing and only help from hard hits over rough terrain.
I wish they had one that was between the SES and Offroad stops.
I have the SES severe service Kit on the front and rear of my F450 Ford and it works excellent for that truck.
I just want a little extra help from the Timbrens. Did I screw up? Do I really need the SES set for my use?
 
If you're looking for bump stops that specifically help when the bed is weighed down, the Sumo Springs are a good option. They can be stiff when you don't have weight though. The Timbren's are a big step up from the stock bump stop, but I don't know if they're designed to support extra weight in the same way as say, an airbag would. Depending on how often the truck is loaded up, you might want to look into airbags or swap those out for the Sumo's. I would probably upgrade the rear shocks to something like a Bilstein 5160 as well if you are loading the bed down a bunch, that should help with the damping also. These trucks aren't really comparable to the F450. FWIW I run the Archive Garage rear bump stop kit (one the best kits on the market IMO), but I do not need any extra support for weighing the bed down.

I was look for a bumpstop like the Timbrens active offoad series but with a little additional weight leveling ability. It does not seem they offer one. Although, on their page's Q&A one of their reps suggested this kit for load leveling a Tundra pulling a 6,500lb camper, so it must provide some. Anyone run the Active offroad stops haul weight, how do they work?
 
I find both the Timbrens and the Sumos are not great. I've had both.

You're better off with a helper spring or add-a-leaf. The ride quality of an actual leaf spring is better than that of rubber or foam.

If you have fancy shocks, either timbren or sumo will limit up travel and prevent you from using that last bit of shock travel.
 
Yep. When it was sitting on the timbers, the ride was very bouncy, as you'd expect from hard rubber—like a solid Wheelbarrow tire. Once I got it lifted it was sitting about 2 inches over the tumbrens and I could feel the bottom out because it was limiting travel of the springs and shocks so they didn't have a chance to ramp up.

Even in Timbren's own marketing video on social media they show a truck that isn't hitting the bump stops, then they put on the timbrens and they ride on the bump stops or impact them all the time.

You shouldn't be hitting the bump stops very often. And you shouldn't be talking about RIDE. You don't want to be riding one the bump stops.

I switched to Sumo Springs which have less rebound over all, but still limit up travel.

I eventually switched to RubberShox Modular bump stops and now I almost never feel the bump, because I never hit them and the springs and shocks have the travel to control compression properly.

A good Add-A-Leaf like the Icon is cheaper than Timbren or Sumo and is a better product for controlling load.

With the offroad Timbrens, I noticed none of that. Are you sure you had them. The ride is actually BETTER than factory

Noticed the same with my Wheelers rear bumps (LOVE them up front tho). Can feel the harsh bottom outs of those pedestals with them.

No such issues since switching to the Archive's. MUCH better design and MUCH smoother when you hit them. Can hardly feel the rear anymore and gained at least an inch of uptravel.
