    These Billet Aluminum return lines are the cats A$$

    Fit perfectly had everything I needed and I'm looking forward to never buying a return line kit again. Not sure what happened these days but seems like every spring I've been having to replace the return line kit after the winter slumber and I expect that won't be the case anymore.
