OME Rough Ride, Spring Swap?

Hey, I'm new here so forgive me if I make any mistakes on where I post this.

I have a 06 4runner sport edition v6. Currently have the following installed.

Front shocks: ome 9000
Front coils: one 884
Rear shocks: 6004
Rear coils: 895

Everything else is pretty much stock (I'm working on it). The drivability is much better and off road capability is great, I've even taken it on the dunes and some trails. But if I'm being honest on road comfort has really suffered and thats where it i am 99% of the time. I don't drive around 300 lbs of stuff I'm my truck all the time either.

Wondering if swapping the rear springs out to something lighter like bilstiens would help? I know ome valves these to match the spring but Im also not driving around with the stated 600 lbs of load its rated for.

Thoughts? Or any recommendations ?

 

Welcome to the forum.

 

ride quality will mostly come from the shock valving, not so much the spring.

 

So no way to soften the ride?
