Anybody know if the 416 shocks use oil or are they solely air? If they do use some oil= how much and what kind? Am getting ready to mount an used but good set on my 1500. If they do use some oil I should drain the old out and in with the new. Thanks all... Ride On

Yes, according to the seal replacement instructions from their website they use 2 ozs. of DexronII ATF fluid in each shock.

Probably the biggest challenge is knowing all the old oil is out of them or whether there is still some in there and you need to add less.

The seal replacement instructions I have are for the eye to eye version of the 416's which is used on the 1000's and 1100's.

The 6 ozs comes into play with the 1500 version of the 416 shocks.

Yep, oil inside to provide shock absorbing, spring inside to support the load. The only way to empty them that I know is to disassemble the shock and pump the oil out. or compress the shock. I compressed a pair of 416s using a couple of large turnbuckles and a piece of 5/8" all thread. I put the turnbuckles on either side of the shock with the all thread through the eyes of the two turnbuckles and the shock eye. Nuts with washers on each side of the turnbuckle eyes held things nice and square. Then it's merely a matter of screwing down the turnbuckles to compress the shock. I removed the snap ring and the seal to drain out the oil. You can modify the turnbuckle rig to compress the shock from the bottom eye and the top housing which will expose the keeper on top that holds the body and spring together.
