Good they are locked in for 6 months. Someone wanted $$ from the pump and sold afterwards.
Anyone ever worked as a mechanic would know Even with the addition of an xl retrofit you still have regular oil, and fluid changes to perform along with belt checks, as well as unnecessary unusual stress on transmissions and universal joints; not to mention additional wiring and bolts to check torque on every six months or so. Most people don’t even know chassis/frame bolts are supposed to be checked periodically because they don’t read their vehicles operational manual.
So my statement of maintenance to perform still stands as valid.
