Rear End suspension help?

Reporting back to follow up on my previous post and offer feedback for the OP as I faced the same set of issues. Reminder, I have a 2018 SR5 TRD DC with ARE Topper and Bedslide. The added weight on the box caused my rear suspension to engage the overload leaf too frequently resulting in a 'bucking' effect in the rear and a floating front suspension. Ride height dropped in the rear.

I installed a set of Sumo Springs and 2 small blocks on my rear suspension this weekend. I went with the blue Sumos and 3/4" inch lift block for left rear and 3/8" for right rear.

He is the result.
@1.0 inch increase in rear ride height.

After about 250 miles road time, highway and gravel roads, I am very pleased with the set up. The Sumos support the factory leafs without being harsh. The combination of the minor lift in the rear and the Sumos shift some weight back to the front and now the front has to carry more weight like it was designed to rather than float along as the rear bounced off the overload leafs. Both front and rear suspension seem to work better together. Steering responsiveness has returned to similar to unloaded characteristics.

So, give me a couple more months and I'll have complete experience with the setup. The Sumos need to be tested in our cold northern plains temps before I give them full endorsement. If they don't turn into hockey pucks in below zero temps I will be completely satisfied.

 

Do you have an update on your Sumo Springs after the winter months?

 

So for the guy that doesnt load up so often, maybe 3x a year, would you guys recommend sumos or air bags?..I never tow, just load up for camping, fishing gear and multiple coolers.

 

I am totally happy with the Sumo springs. I am approaching 20,000 miles with them so far. They did not seem to get hard in below zero temperatures this winter. I would install them again without a second thought and.

 

I am in the same situation as you and from what i've read so far, it seems like airbags would be the way to go for occasional loads. The plus side of airbags is that its adjustable so you can inflate as necessary. I just bought some firestones ride rite with daystar cradles and will be installing it next week. Will try it out this year to see how well it works.

 

Lmk how it goes and post pics please.
