Stronger shocks? Bottoming out at times.

I lowered the rear of my pickup, but not radically. I have a bottom out situation that happens when there is a large or sharp dip and the rear goes up and on the down part it bottoms out. It is hitting the bump stops and they are new.
The truck has a very nice ride right now but not too soft. Has anyone every tried stiffer shocks on the rear and I am wondering how it will affect the ride?
Any other suggestions other that just living with it?
I uploaded some pictures in my photos.

shocks

Shocks are there for a dampening effect and not to limit the movement as I'm sure you already know. Replacing the shock with a "stiffer" one will only give a choppy ride and still bottom out. The solution is to remount the shock so the axle hits the bump before the shock bottoms out or replace the shock with one that has a longer stroke. To stop, or reduce would be a better term, the bottoming the springs must be stiffened. Leaf, add one. Coilovers, add preload. Coils, add a spacer.

The real fix for this is what should be done on any lowered truck with the problem....the frame gets a C-notch over the axle and the bump stop moved up accordingly, so the axle no longer hits at peak downward travel.

A stiffer shock is not going to fix the problem, unless it is a coil-over shock and the downside to that is it will stiffen the ride, just like adding stiffer main springs will do.

Shocks control speed of movement in a suspension, they don't control distance of movement.

There are also reduced thickness urethane bump stops sold by Energy Suspension and others, maybe that is all you need??

I don't need much. I'll check out the reduced thickness bump stops. Mine are pretty thick..about 3 inchs.
Thanks for the ideas and help.

If your shocks worked fine before you lowered your truck, then you now need shorter shocks, shorter by the amount you have lowered your truck.

i'd cut out half the bump stop first to see if that is the solution
my lowered and c-notch my 58 truk and occasionally bottomed out on the short bump stops
michigan roads are crap, usually it would take a big swale that set you in the seat hard to bottom out
i went with air shocks and experimented with various pressures, fixed my problem
i should have used a bigger c-notch but didn't want to change the bed height

What is the suspension setup?

Leafs, coils, coil overs, bags, hydro?

I like coil over nitrogen adjustable shocks. It allows you to adjust the rate while soaking up bumps.

If you plan on using it as a truck then an adjustable suspension is key. If you want it as something that never sees dirt then run it with some longer hangers to allow for more stroke staying above the bottom of the rims of course.

No idea what this is on makes it a bit hard to paint a picture of what you started with and what you currently have.
