Ugrade Rear-Suspension without Off-Road Kits

Was wondering if anyone has tried upgrading their rear dampeners to include coil springs as opposed to external reservoirs. The reason why I ask is because I frequent a buddy’s house, wherein the road leading to his place is littered with pot holes and deep grooves- almost as if you’d be off-roading. I bought the Bilstein 5100 series for my front end, 5160 series for the rear, and had my leaf springs replaced (dealership had to take care of the recall) in preparation for my visits.

The front end handles the shock sufficiently for its price point, however the rear end can’t seem to handle the impact as well due to it not including coil springs.

I was wondering why my buddy’s Ram has a crazy smooth suspension on his roads and took a look at his suspension; it has coil springs.

Honestly this is also my first time really paying attention to what my truck has to offer. I’m looking to find a way to make my ride a lot smoother and capable of handling more, should I need it.

Has anyone successfully adapted/fabricated/Jerry-rigged Dampeners w/coil-springs onto their 2nd Gen Tacos?

 

It has nothing to do with leafs vs coils in the rear.

It's simply the fact that the ass end of our trucks are very light so there isn't much mass for the suspension to work against

 

Don't have a 2nd gen so don't take my word, but something to think about:
The rear not being able to take the impact is common w/ tacos due to being light. Get a custom valve rear, replace hangers, get better leafs or at least get something other than Bilstein because Bilstein has digressive valving so it's going to be stiff.
