What size spacers /4600 Bilsteins

‘21 Limited. Looking to install airbags on the rear and level the front, has TRD off-road package/4600s on it. What size spacers do I put on the front? Does it make any difference as to what brand?

 

two inch lift in front levels the truck. If you want a spacer lift, they are all pretty much the same. Toytec has several options for spacers and so do lots of other vendors. If you google search tundra spacer lift you will find a bunch of options.

 

Two inch will definitely get you dead level. But the problem is that with slightest bit of weight in the bed or on the hitch it will look lower in the rear. I went with a .50 Coach Builder spacer which gave me about .8 lift which is perfect. With 400 pounds in the bed it was dead level.

 

I put airbags on my previous TRD Pro to avoid the rear end sag when trailering or loading the bed as it was level to start. I like being able to increase the trailer tongue weight capacity with the bags if needed. I could leave it and not worry about it but I am considering alternatives.

 

airbags address rear end sag, in a band aid kind of way. They do nothing to increase any hauling or towing capacity and do not increase payload or tongue weight capacity. All that is based on how toyota designed and built the truck.

 

I agree with your assessment, I did not mention payload capacity and I don't wish to increase the actual tongue weight capacity but to prevent the tongue weight from sagging the rear end lower than the front end disproportionately when both are at the same level to start with. However that needs to be worded is what I am trying to convey. Considering the variability of towing different trailers and payloads, the only way to compensate the rear end sag relative to that variability is with airbags that I am aware of.
