Im replacing the ***** skyjacker shocks that came w/ my 5inch kit w/ bilstien 5100's. What stroke leangth should I get 10, 12, or 14 inch. (85 runner w/ 5 inch springs and 35's).....Thanks

You need to measure for yourself. Too long of a shock and it wont fit in the mount. Too short of a shock and it will overextend and limit your travel.

Find somewhere that you can fully flex your suspension out. Stuff the tire in the wheel well as far as it can go or as far as you want it to go, and measure from the top shock mount to the bottom. This is your compressed length. Now go to the other side, and meausure top to bottom. This is your extended length. Take those numbers, and match them up with the numbers for the different shocks. Each shock should give you extended and collapsed lengths.
