I chose the add a leafs.

 

Leaf will affect the unloaded ride quality

 

Last spring I bought a yard of mulch. 2 buckets from the seller backhoe. He was really good. He was concerned that the mulch weight 1 -1/2 tons and that the Tundra was a half ton truck. Anyway he very carefully placed it in and I only drove less than a mile. We looked at the springs and the snubbers were touching. He said he'd never seen an F150 take that much weight. Not that I plan on overloading the truck often, but I was thinking about some additional springing in the back. Can you point me to where I would look for the options you mentioned in your post? Is this stuff a garage mechanic can install? Thanks

 

I found both of these items I mentioned on ebay. I would think that any good shop could easily install either of these on your truck. I hope this helps

 

Leaf is the better choice. I've read of bad stuff with the springs.

If you really don't want to sag with a load, add air bags.

 

Hmm, I've had good luck then with Hellwig helper springs.

Note: there's damp mulch in pickup bed, second photo shows this.

The other option is Timbrens, google them. They basically dont effect the ride of the truck when it is empty but when loaded help hold the load up and prevent it from bottoming out.

I have a thread here that mentions bottoming out and some guys offered alternatives.

 

I put a set of Hellwig Helper Springs on my truck last spring and immediately noticed a difference when towing. Kept the bed bounce to a minimum when going over bumps and that squishy feeling went away. Easy install and did not stiffen up the ride to much when unloaded.

 

Had a shop install the Hellwig Helper Springs (2500 lbs) a couple of months ago. The springs can be adjusted to your needs. For my truck the result was an inch of lift since I have them set to be slightly engaged with my normal load. Have between 300 and 500 lbs of tools etc. in bed. We thought it actually improved the ride slightly, less bouncy. Pulled out travel trailer about 100 miles with them so far and the ride and sag did improve. The real test will be this summer when we have our truck loaded down with a generator, two jerry cans of fuel, an inflatable rubber raft with battery and trolling motor, and the tools mentioned earlier. Will comment after that trip.

 

Been using the hellwigs over a year now. They really have helped stabilized my Tundra when towing. They seemed to add the extra suspension needed on the back of the truck. We have towed our 6500 lb tt 6000 miles or so since my last comment. I would definitely recommend them.

 

I haven't had exeriemce with any of those but I think air bags would be a better option a little more money but worth it.

 

Why would air bags be better than a stout set progressive helper springs? The Hellwigs are of excellent quality. Set'em once and you're done.

 

Oh, they're powder coated too. Wish my stock springs were of the quality as Hellwigs.

 

I bought a pair of tuffcountry add-a-leafs (#85750), plan to install soon. And will post a follow-up. also will install front 5100's. Just want an extra 500 lb capacity, and be a little higher in the rear than the front after the 5100 install. Welcome your comments or suggestions. I tow a 27-ft Travel trailer (6,000 lbs +-).

 

I ordered a set of these and am trying to find if I need longer U bolts.

Did you ever install yours?

Thanks

 

can someone tell me if the tuff country # 85750 will fit the 2wd 2010 tundra ?

 

I installed them today. Feel great & fixed the 5100 droop.
