Whats the best suspension for my work truck? Heavy load, on road only.

Hey all!

I have a 2019 Tacoma TRD sport, crew cab, 4WD. I use it as a service vehicle for my business. I've put on a utility bed on the back. I weighed the truck with the stock bed empty and with the utility bed loaded as it usually is; it's about 700 lbs heavier on the rear axle. This had it feeling pretty saggy/bouncy when I first set it up. I installed airlift bags on the rear leaf springs, and that helped. But the bags and compressor have failed a couple times and I'd like to get the truck to ride nicer anyway.

Ideally, I want the truck to sit an inch or two lower than stock. I prefer a stiff/firm ride. I like feeling all the bumps in the road. I don't like when the truck feels "floaty". I want minimal body roll, side to side or front to back. I don't take the truck off-road; I just want it to feel as crisp and stable as possible on asphalt while carrying my heavy tools.

Everything on the truck is stock except the utility bed and the airlift bags(which I'm pretty sure I want to remove once I've beefed up the suspension).

I am considering using a lowering kit to put the springs under the axle and getting some firm, heavy-duty leaf springs and shocks. Does that seem like a good idea for my situation? Any better ideas?
What leaf springs and shocks should I use to get the firmest ride?

I would appreciate any ideas; thanks!

 

according to another thread, the dobinson suspension upgrade with 33" tires makes a tacoma better than a race-prepped miata on any road.

 

if you have a constant load, new leaf springs Will be the best option. There are a few aftermarket springs available and I’m sure you can find a spring shop that can custom make a set.

 

You could also add a rear sway bar.Hellwig makes a kit.

 

Moving on, @lelio I suggest calling @memario1214 at Hotshot Off-road. Your situation sounds like a challenge he'd accept.

Caution. There is a weight capacity in your door jamb. Even if new suspension allows you to exceed that, it doesn't make the rest of the truck capable. Things like drive line and brakes are part of that limitation

Please post pics of truck with utility bed. Not sure I've seen one on a Tacoma.
