Well as far as head steads and everything in the build. You'd have to ask Qasim from dryft motorsports. they are 550's and yes a 255 pump. Just some no name brand aftermarket struts and springs. Ride well though.
Almost sure it's a 98, but i can check for confirmation.
and the rucas are off of ebay, (no brand) i believe they were 60 or 80 bucks. Look legit though.
