So a question for the collective and gathering parts for the wintertime project:
Got a couple pairs of Billy's from Bruce S for my front end that I am planning on swapping out. Plan was to rebuild the sets and then swap out the a-arms with new ball joints bushings ect. Currently the car is lowered in the front about 1 -1/2 inches lower than stock spec with the current a-arms not quite parallel to the ground. I run a bump steer kit as well...(although I still get some bump steer). I noticed that the yellow inserts have shorter piston length but have the same part number. Question: Which ones should I run on the car for the current set up and does anybody have any experience on the valving set up for the Billy's? I am told they will rebuild them for $75 each. Car will be street driven mostly. I am concerned about bottoming out the longer length pistons and busting the valving with the car lowered in the front. Thanks   |

The way to avoid damaging the valves is to install plastic packing washers which prevent the pistons from bottoming.

All other things being equal, I'd use the shorter inserts on a lowered car. Not that there's a big difference between those two.
