Simple questions deserve simple answers. From Matt:
"The original rebuild is around $950, due to the need for 'rebuildable' aluminum seal heads from KYB. These are $70 each so they add $280 to the first rebuild price. After the initial rebuild, they can once again be rebuilt for just $140 per shock, which includes a new oil seal and oil. It can take approximately 2 weeks to rebuild. If you have any questions feel free to call or email."
I have a spare set that I'm about to send in for rebuild. After that, I'll be selling the set I currently have on the truck in the event someone wants to send those in for rebuild. I'm amenable to sending them straight to Matt to save on the extra shipping cost if you'd like.
