OEM length rear shocks with extenders?

[chevymotocross]

Flip kit in rear with 1'' lowering shackles and c-notch. Front consists of 2.5 spindles and 2'' Belltech springs.

Doetsch-Tech shocks all around.

Front is harsh over bumpy roads and the back is extremely bouncy. I recently added Western Chassis shock extenders in hopes of a better ride out back. If anything, it made the ride even bouncier!

Is it possible to run oem-length shocks with the extenders with my setup? I'm thinking any of these "drop shocks" are just too rough for what I'm looking for. I know it's a truck and I know it's lowered, but there has to be a better ride than this?

I already found a vendor who sells KYB GR-2 for the front lowered 2''.
