AE big bore shoccks are good. Ive had my truck since last spring and Ive only rebuilt them 3 times. The last time was 1.5 gallons ago and theyre still perfect. There is a little tool set that might help you. I think it comes with the RC8TCE and RC8B or you can get it separately part number 89358.

It also can be used for installing and removing clutch shoes.
