Lets discuss Power Steering Pump options. To begin, I am running a 2014 JKU (3.6L) on Tons and 40's. Hydro assist using stock tapped box and PSC 1.75" x 6.75" ram. With the stock pump, steering worked, but left a bit to be desired at lower RPM's. Ended up ordered the PSC PK36JP1 power steering pump kit (pump, reservoir, cooler, etc.). Steering works great now. For those that have not installed the pump that comes with this kit (SP43362J-2402), the factory 3.6 mounting bracket is removed and an entirely new bracket is installed with the new pump. The SP43362J is the actual pump part number, and 2402 designates the pully part number, in this instance its a 5.5" Serpentine pulley. The factory belt length is also changed, requiring a 900K6 belt now (90.5").
Shortly after building my rig, a buddy does almost the same built with his 2007 JKU (3.8L). Tons and 40's again, with the same PSC 1.75" x 6.75" ram. From the get go he went ahead and upgraded the PS Pump utilizing the PSC kit for his Jeep (PK38JP1). This kit includes PS pump number SP43362J-3608 same pump with a different pulley (6" Serpentine pulley in this case). The other noticeable difference is that the 3.8 does not require you to change the PS pump mounting bracket in order to install the PSC pump, and actually utilizes the factory belt length, which is the same 900K6 (90.5") that the 3.6 is swapped over to.
So, the question/ determination here is what to do for a spare PS pump. I could pony up $425 for a complete SP43362J-2402 pump with pulley, or $350 without the pulley. We could carry 1 pump without pulley between both of us since when wheeling we are generally together, which is much cheaper than each carrying $350 pumps. OR, he can carry his factory pump, or a factory replacement as a spare would just need an adapter hose to connect to the PSC reservoir, or mod the pump to utilize a fitting to go to -10AN. Seeing that the PSC conversion makes both the 3.6 and 3.8 use the same pump, I should theoretically be able to carry the same thing, a replacement 3.8 PS pump, but with the appropriate 5.5" pulley vs the 6". Has anyone else dug into this and came to the same conclusion?? I'm just trying to avoid carrying more expensive spares than I need to, but at the same time making sure I have something to extend a wheeling trip.
The other question to this ( I havent had time to sit and look into this), is what is so different on the physical mounting of the 3.6 and 3.8 pump that makes them different and requires a different bracket for the 3.6?
