Tons of posts about this....use search function.... "OEM shocks", "bump stops", and such.

VERY stiff OEM ride....shocks are extremely rough.

Many have replaced them with Rancho 9000s with the 9 way adjustable settings.

Some of us (myself, vt_mav) have recently cut our rear bump stops in half and have seen a TREMENDOUS improvement in that real jarring/slamming effect on the rear of the vehicle.
