i just had a pair rebuilt and got them back 3 or 4 weeks ago...
call Paul at:
Koni Industries
1961-A International Way
Hebron,Ky 41048
(859) 586-4100
the total cost of my rebuild was $350.00 this included shipping back to me.
the cost will vary depending on what parts are needed to be replaced..i think Paul qouted me $120.00 per shock plus parts..
cost me about $25.00 to send them out there...
depending on what type shock you run or have, you need to weigh out the rebuild cost vs cost for a new set...
if you are not looking for a fancy shock ( single adjustable etc...) you can get them pretty cheap..
but in my case my shocks were about $500.00 (each) to replace so the rebuild was worth the cost.
also they will send you the dyno sheet back with the shocks..
also don't be in a rush..it took 5 weeks for me to get mine back...
hope this helps.
Brian
