Designed for 1997–2006 Jeep Wrangler TJ and 2004–2006 Wrangler Unlimited LJ models equipped with the 4.0L inline-six engine, this package provides the hydraulic supply needed for larger tires, upgraded steering components, and demanding off-road applications.\u003c\/p\u003e\n\u003cp\u003eAvailable for either cylinder-assist steering or full hydraulic steering, the kit allows builders to match pump performance and plumbing to their steering system. The cylinder-assist version supports a conventional steering gearbox with an auxiliary hydraulic cylinder, while the full hydraulic version is designed to supply a hydraulic steering control valve and double-ended steering cylinder. Both configurations include a PSC high-performance pump, filtered remote reservoir, mounting bracket, hydraulic plumbing, dedicated fluid cooler, and PSC steering fluid. Proper cooling, clean fluid, and correct hose routing are essential to keeping the system responsive and reliable during slow-speed rock crawling and repeated steering loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes (Dependent on Customer Selection):\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch4\u003ePK40JP2 – Cylinder

PK40JP2 and PK40JP2-FH?\u003c\/h3\u003e\n\u003cp\u003ePK40JP2 is designed for a conventional steering gearbox with hydraulic cylinder assist. PK40JP2-FH is designed for full hydraulic steering systems that use a hydraulic control valve and steering cylinder instead of a conventional mechanical steering gearbox. The packages use different PSC pumps, reservoir configurations, and cooler components to match their intended steering applications.\u003c\/p\u003e\n\u003ch3\u003eWhy upgrade the factory Jeep 4.0L power steering pump?\u003c\/h3\u003e\n\u003cp\u003eLarger tires, increased front axle weight, lockers, and demanding terrain place additional loads on the steering system. A high-flow performance pump helps supply the hydraulic fluid needed by upgraded steering components, particularly during slow-speed rock crawling where engine RPM is low and steering loads can be high.\u003c\/p\u003e\n\u003ch3\u003eDoes this kit include everything needed for hydraulic steering?\u003c\/h3\u003e\n\u003cp\u003eNo. These packages supply the performance pump, remote reservoir, cooling components, and associated plumbing for the selected steering configuration. The steering gearbox, assist cylinder, full hydraulic control valve, and steering cylinder must be selected separately as required by the complete steering system.\u003c\/p\u003e\n\u003ch3\u003eWhy is a remote reservoir included?\u003c\/h3\u003e\n\u003cp\u003eA remote reservoir increases flexibility in steering system packaging while providing a dedicated fluid supply to the pump. The included internal filter helps manage fluid contamination, and proper reservoir placement supports consistent pump operation. The reservoir should be mounted and plumbed according to PSC's installation requirements.\u003c\/p\u003e\n\u003ch3\u003eIs the included steering cooler required?\u003c\/h3\u003e\n\u003cp\u003eYes. PSC specifies a dedicated fluid cooler as part of these performance steering packages. Hydraulic steering systems can generate substantial heat during repeated steering inputs, slow-speed crawling, and high-load operation. The cooler helps control fluid temperature and protect the pump, seals, hoses, and other hydraulic components.\u003c\/p\u003e\n\u003ch3\u003eWill this pump kit fit a Jeep Wrangler TJ with a 2.5L engine?\u003c\/h3\u003e\n\u003cp\u003eThis listing is specifically configured around the Jeep 4.0L engine and its accessory mounting arrangement. Do not assume direct compatibility with the 2.5L engine. Confirm the correct pump bracket, pulley, and belt configuration with PSC before ordering for a four-cylinder application.\u003c\/p\u003e\n\u003ch3\u003eWhy is pulley alignment important during installation?\u003c\/h3\u003e\n\u003cp\u003eIncorrect pulley alignment can cause belt tracking problems, premature belt wear, pump bearing loads, and thrown belts. Verify pulley position, belt length, and clearance with the engine's complete accessory-drive system before final assembly.\u003c\/p\u003e\n\u003ch3\u003eHow should the steering system be prepared before installing the new pump?\u003c\/h3\u003e\n\u003cp\u003eFlush the existing hydraulic system to remove old fluid and contamination. Install the pump, reservoir, cooler, and hoses using the correct fittings and routing. Fill with PSC-approved fluid, then follow the manufacturer's bleeding procedure to remove trapped air before operating the system under load. Aerated fluid can cause noise, inconsistent steering response, and pump damage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"PSC Motorsports","offers":[{"title":"Cylinder Assist","offer_id":67879226179949,"sku":"PK40JP2","price":1240.0,"currency_code":"USD","in_stock":true},{"title":"Full Hydraulic","offer_id":67879226212717,"sku":"PK40JP2-FH","price":1260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/1145\/3037\/files\/pk40jp2.png?v=1793638140","url":"https:\/\/craneaxle.com\/products\/power-steering-pump-kits-jeep-wrangler-tj-lj-1995-2006","provider":"Crane Axle","version":"1.0","type":"link"}
