This is useful when the steering upgrade needs to address both the gear and its fluid supply rather than replacing a pump alone. The larger gearbox requires clearance checks around track bars and reinforcement braces, and PSC specifies the complete matched system for warranty coverage. A separate assist cylinder is not listed among the two main included assemblies.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSG688R Big Bore XD steering gear\u003c\/li\u003e\n\u003cli\u003ePK36JP1 high-performance pump kit\u003c\/li\u003e\n\u003cli\u003ePump-kit reservoir, cooler, anti-splash valve, belt, brackets, hoses, and fittings\u003c\/li\u003e\n\u003cli\u003e4 quarts PSC 715 fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cdetails class=\"details\"\u003e\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e \u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath class=\"vertical\" d=\"M2.75 7H11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\u003cpath class=\"horizontal\" d=\"M7 2.75L7 11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\u003cdiv class=\"details-content rte\"\u003e\u003ctable class=\"custom-specs-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003ePSC Motorsports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart number(s)\u003c\/th\u003e\n\u003ctd\u003eSK688R36JP1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSteering gear\u003c\/th\u003e\n\u003ctd\u003eBig Bore XD Cylinder Assist\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePump kit\u003c\/th\u003e\n\u003ctd\u003ePK36JP1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCylinder \/ assist ram\u003c\/th\u003e\n\u003ctd\u003eNot listed as included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSteering Gear and Pump Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Application\u003c\/td\u003e\n\u003ctd\u003eJK\/JKU builds on 35-inch or larger tires; Technical trails and rock crawling; Matched steering gear and pump upgrades\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e\u003c\/details\u003e\n\n\u003chr\u003e\n\n\u003cdetails class=\"details\"\u003e\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e \u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath class=\"vertical\" d=\"M2.75 7H11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\u003cpath class=\"horizontal\" d=\"M7 2.75L7 11.25\" stroke=\"currentColor\" stroke-width=\"var(--icon-stroke-width)\" stroke-linecap=\"round\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\u003cdiv class=\"details-content rte\"\u003e\n\u003ctable class=\"custom-specs-table\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth scope=\"row\"\u003eJeep Wrangler JK \/ JKU, 2-door or 4-door, 3.6L\u003c\/th\u003e\n\u003ctd\u003e2012-2018\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eInstall the matched PSC system together.
