My guy is $35 / shock- new seals, oil, nitro and re-valve with mostly a 2-3 day turn around as he works a full time job + does a lot of the dirt car racers set ups.
I'm 300# on an '09 RTX with shocks re-valved, stock springs & just added BOP 4 position blocks for a bit more adjustment, it doesn't bottom out all to often and had no issues with a nice ride in the 3 years I've had it.
