Steer axle air ride assist. NOT LOW RIDER.

Find a used front set up rated for 20k and swap it out.

Just a thaught

 

For sure you need to upgrade axles. First off the components of a 12k axle won't handle that safely for long. If the beam does hold up, you've got smaller springs, kingpins, wheel ends, bearings, spindles, rims, brakes. The whole 9 yards is too weak. Find a 20k takeoff. Maybe $2000-$4000 complete. Look for one that has good kingpins. You might even find a brand new takeoff for under $3500 complete with brakes and drums. Not a hard job to switch out. New springs, hangers, everything. I think it's easier than replacing kingpins, I've done both btw. Easy rolling old out and new in. At least look for a 14k at the least. You'll be glad you did

 

Wowwww.....people that comment on your stuff are now paranoid mommies??? Dang...good luck with your under rated frontend disaster guy.

 

Seriously, an air assist won't last long. The airbags for that system are not set up for the weight. You'll be constantly blowing them and replacing them. Financially speaking, the air assist will cost you more in the
Long run. Is that more of the answer you were looking for? If not I can lie to you and say, "yup it will help you a bunch". But that's just not the case. But hey if you want to drop the coin on it, by all means go for it. Your money, your business. Go for it. I'm sure the guys selling it will tell you, yup it's just what you need. But common sense should tell you it's the wrong thing to do.

Is that a Better answer for you?

 

All I will say is, if the metal has any flaws you will know soon enough.

The weight alone without movement will find the weak spot.
