Helping Tundra with Rear Sag

[Happy Vibe]

I don't understand how you can put hundreds of ponds of weight on your TV and not have some sag. Even if I get in the bed of my truck it sags a little. The main thing you don't want is the front suspension to be lower than stock when the WDH is engaged. I don't know how you can get the rear up to stock without compressing the front.

Not saying it is, I'm just trying to get an explanation as to why the wdh instructions say the rear should be lower than original, if all it takes is tinkering with the stock adjustments to get it back to normal height. Has nothing at all to do my truck!

I have 08 tundra with airlift 5000 bags. Perfect for my needs. Does Not Add load carrying ability but does keep truck from bouncing and sagging.

Okay the sag isn't as severe as I thought but since I have a mechanic friend who recommended them, I'm going to have him install some Timbren rear supports on the truck. (They cost about half as much as the air bags but no maintenance afterwards.)

I have them in my Tundra and they work great.

Just because something costs less doesn't necessarily produce the best all around results. Airbags are adjustable Timbrens are not.

Wow I'm totally po'd.

I went to mount the Timbren rear suspension bumpers and not one but both are detective! Whoever welded the joints did not even come close to a 90-degree angle and I can't even tighten then down.
I'm done with anything Timbren makes...returning for a refund. (Glad Amazon makes it easy.)

Regarding some previous posts:

Dealers are notorious for not setting up the WDH correctly. My dealer techs stepped back, and said "that looks about right", and sent me off on the highway. Their setup only replaced 60 lbs. of the "lost" 300 lbs. back to the front axle.

If you get the most of the lost weight back on the front axle, then the rear fender measurements should be less than without a trailer. Many trucks with high rear ends settle down nicely to almost level with a properly adjusted WDH, with no air bags, timbrens, or over load springs needed. The rear end of trucks are made to carry some weight.....but not too much weight.....that is why you have rear axle weight ratings. A properly setup WDH should keep both the front and rear axles within the weight ratings. If not, then you might need a bigger truck.
