Bottoming out rear shock
My bike 2016 Santa Cruz Heckler.
Brand new Fox DHX2 coil.

Ok a bit of history for the mystery.
My original bike was a 2009
SC Heckler with a Fox DHX 5 coil.
That shock was sent out to Fox for rebuild a few times over the years.
In 2016ish the frame would not hold new pivot bearing so a new frame was purchased from SC as a crash replacement (as I was the original owner. ) SC has great customer service.

So the new frame was for the new (at that time) 27.5 wheels. Almost everything was changed for the new frame. Wheels, bars, brakes, drivetrain.
The only thing that wasn’t changed was the original DHX 5.

This winter it was time for rebuild.
I sent out my shock and fork for rebuild.
The fork was rebuilt and good to go.
The shaft of the shock was worn and couldn’t be rebuilt.

I bought a new Fox DHX 2.
I reused the 450 pound spring that I’ve been using since I bought the first bike.

I set the hi and low compression and
hi and low rebound to the recommend settings per the owners manual for the shock after I set 30% sag.
The rear will bottom out easily on my regular trails/drops/jumps.
I increased the hi speed compression.
It helped a little but I’ll still bottom out on stuff that I never did before with the old shock.

Can anyone help?

You new frame has slightly different leverage ratio than old one, thats why probably different spring would be needed in the first place, not sure how you managed with old spring in the first place. Try harder spring.
