R series are the ones you want, the difference is when you have and f series the valving will be 10/10 20/20 50/50 90/90, with the r series it will have a fixed firm compression that will be at 90.

so it will be 90/10 90/20/ 90 /30/ 90/50 and so on.

Problem with the f shocks is if you have it lose to come up fast it will be 10/10 valving and the front will also come down fast, it will handle like crap and if you pulled the tires and had to get out of the gas it would bottom out big time.

Buy the R series QA1's

but they are not double adjustable. If you want double adjustable the strange double adjustable are the least expensive at 250 a piece. next best is afco which are more expensive.

yes f's can be revalved to r's call qa1 they will give you a service center number to you locally, expect to pay about 200 to rebuild the shock with new parts and have them revalved.

Some people will claim less but once you get them valved and change to all new parts that's what you'll be around.

You can adjust the extention of the shock the compression is fixed firm.

Afco double adjustables will adjust extension and you can adjust compression independently, you can get the strange ones from jegs or summit or a sponsor, they in my opinion are better than QA1's, but not as good as Afco's, but they are a good amount less.
