I installed the freebee hand-me-down Rubi shocks a buddy gave.
They had a few thousand miles, and initially seemed an upgrade to my Sahara JK with 60,000 miles.
In 2000 mile road test, for all but 80 miles, they seemed well worth the cost of installation. Had I actually paid for them, I would be disappointed.
Currently I am researching what REAL upgrade shocks might be.
I continue to go without a lift, and it seems less is written about what choices to make.
The Rubi replacements for me, were "better" in general road bumps, much improved on speed bumps, but "FAIL" on gravel stutter bumps & severe wash board road I had traveled a year ago with OEM Sahara shocks.
Locally Craigs List frequently has Rubi take offs for $80-150.
Jeep Parts Dept. gave me print out for stock Sahara shocks for around $250/pair.
Good luck in your search. And if you find interesting data please post.
