Modified 2012 + jk POWER STEERING pump

well guys , i'm sooooo tired of slow hydro assist (1.75" ram) at idle speed i bite the bullet and open up the stock pump.
since i havent found anyone doing this ... here goes. down inside the main fitting there was a ridge ,,, thats gone and filed clean... and the needle flow restrictor is filed down and smoother just a bit.

I'll let you know how it works when my new box shows up tuesday

I would have tried the 1.5" ram before messing with your pump. Mine lags a bit only when ripping the wheel from one direction to the other which I dont do very often even when parking. Turn in a steady motion and there is zero lag with the 1.5" ram. On the rocks your turning slow any way not ripping the wheel side to side so it doesnt impact it there either. Other than that it works great but I hope the modified pump works out for you turning that bigger ram.

I've been finding when I really lay into the steering coming off an agressive bump, I definitly hit a lag. A little more flow might not be terrible.

I've been very interested in trying this. Curious to see how it turns out.

Why not get the upgraded pump that PSC sells? Not very expensive. The pump should be matched with the ram. If you want to run a 1.75" ram, you need a larger volume pump. Pretty straight forward.

Shit man im very interested. If it reduces lag and keeps highway manners in check im in. If it reduces lag and fucks you up on the highway im out. Only thing is that he has a 1.75" bore so his driveability will be different than our 1.5"s so that has to be taken into consideration with his review

While I agree, there's value to this.

If you're happy with the force of the ram, but the speed lags a bit it may be worth seeing if more flow (rate) can be pulled from the pump. The PSC pump has too much pressure and flow for a 1.5" ram, which is why it works well with a 1.75".

I like that in heavy bind (tire completely wedged) my 1.5" with stock pump still cuts out. I'd rather that than pop a ball joint from not paying attention and pulling on the wheel.

GREAT NEWS !!!!!!


My steering box is in ram ,hooked up , this steering is 110% better

so same nextsteer box , 1.75" ram , i did change track bar mount to match my inverted Y steering links ( no more low hanging factory style steering ) and the wheel is so much faster going from left to right.

I'm very happy with this set up now !

do you get a ton of binding with that track bar? seems like the axle joint would be in a constant state of binding....same with your knuckle side drag link, at full lock on either side, albeit if thats just a TRE maybe its not that bad.

interesting set up.

no binding , its only 6" up and 6" down from ride height , the bushing has enough flex to it

im still impressed how much better it handles in turns and over wavy spots in the road. no bump steer or diving into left hand turns

What size did you drill out to? And what part of the rod did you change?
