Stud-and-nut fastening provides superior clamping load consistency compared to bolts, reducing the risk of gasket leaks from uneven torque and making repeated oil pan removal easier without damaging the pan rail or block threads. Each stud is manufactured from high-strength alloy steel for long-term reliability under sustained oil temperatures and engine vibration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEngineered specifically for Toyota 1JZ and 2JZ engine oil pan applications\u003c\/li\u003e\n\u003cli\u003eDesigned for use with the Moroso 20948 oil pan for the 1JZ and 2JZ platform\u003c\/li\u003e\n\u003cli\u003eHigh-strength alloy steel studs deliver consistent clamping load across the pan rail\u003c\/li\u003e\n\u003cli\u003eStud-and-nut design makes repeated pan removal easier without re-tapping block threads\u003c\/li\u003e\n\u003cli\u003eHelps maintain gasket sealing integrity over multiple installation cycles\u003c\/li\u003e\n\u003cli\u003eMatched hardware eliminates the need to source mismatched aftermarket fasteners\u003c\/li\u003e\n\u003cli\u003eDirect replacement for factory oil pan bolts on Moroso pan installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003eMOR38948\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eToyota 1JZ \/ 2JZ engine (for Moroso 20948 oil pan)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFastener Type\u003c\/td\u003e\n\u003ctd\u003eOil pan stud kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-strength alloy steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompanion Part\u003c\/td\u003e\n\u003ctd\u003eMoroso 20948 oil pan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e099999839484\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eComplete Moroso MOR38948 oil pan stud kit (studs and nuts)\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eAbout Moroso\u003c\/h4\u003e\u003cp\u003eMoroso Performance Products has manufactured racing and performance automotive components since 1956. Their product line spans oil pans, valve covers, spark plug wires, fuel system components, and hardware kits engineered for competition use. Moroso oil pans and supporting hardware are a popular choice in the Toyota JZ engine swap and build community for their deep-sump capacity and precision fitment.\u003c\/p\u003e\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\u003cstrong\u003eWhat oil pan is the Moroso MOR38948 stud kit designed for?\u003c\/strong\u003e\u003cp\u003eThe MOR38948 stud kit is designed to be used with the Moroso 20948 oil pan for Toyota 1JZ and 2JZ engines. It is not a universal stud kit and should be used specifically with the matching Moroso pan to ensure correct thread engagement and pan rail compatibility.\u003c\/p\u003e\u003cstrong\u003eWhy use studs instead of bolts for an oil pan?\u003c\/strong\u003e\u003cp\u003eStuds provide more consistent clamping force across the pan rail when torqued because the stud threads remain stationary while only the nut is rotated. This reduces the risk of twisting the gasket or applying uneven sealing load, which is especially important on performance engines that see repeated oil pan removal during maintenance.\u003c\/p\u003e\u003cstrong\u003eDo the MOR38948 studs thread directly into the engine block?\u003c\/strong\u003e\u003cp\u003eYes. The studs are designed to thread into the factory oil pan bolt holes in the Toyota 1JZ or 2JZ block, replacing the standard bolts. Always apply thread locker or anti-seize to the stud-end threads per Moroso's installation instructions to prevent backing out over time.\u003c\/p\u003e\u003cstrong\u003eIs the MOR38948 compatible with both the 1JZ-GTE and 2JZ-GTE engines?\u003c\/strong\u003e\u003cp\u003eThe MOR38948 is listed for both 1JZ and 2JZ applications in conjunction with the Moroso 20948 oil pan. Confirm pan fitment with your specific engine variant before ordering, as block casting differences between the 1JZ and 2JZ may affect sump clearance and pan rail geometry.\u003c\/p\u003e\u003cstrong\u003eDoes the MOR38948 include a new oil pan gasket?\u003c\/strong\u003e\u003cp\u003eNo. The MOR38948 is a stud kit only. A compatible oil pan gasket must be purchased separately. Moroso recommends using a quality RTV sealant or replacement gasket appropriate for your specific engine and pan combination.\u003c\/p\u003e\u003cstrong\u003eHow many studs and nuts are included in the MOR38948 kit?\u003c\/strong\u003e\u003cp\u003eThe complete kit includes the full complement of studs and nuts required to secure the Moroso 20948 oil pan to the Toyota 1JZ or 2JZ block. Consult the Moroso product page or packaging for the exact quantity for your specific application.\u003c\/p\u003e\u003cstrong\u003eCan I reuse the MOR38948 studs after removing the oil pan?\u003c\/strong\u003e\u003cp\u003eYes. Stud fasteners are designed for repeated use. Inspect studs for thread damage or stretching during each removal, and replace any fasteners that show signs of wear or deformation before reinstalling the pan.\u003c\/p\u003e\u003cstrong\u003eIs the MOR38948 stud kit available as a standalone item or only with the Moroso pan?\u003c\/strong\u003e\u003cp\u003eThe MOR38948 is sold as a standalone stud kit. This allows builders who already own the Moroso 20948 oil pan to replace worn or lost hardware without purchasing a new complete pan assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\u003col\u003e\n\u003cli\u003eDrain the engine oil completely and remove the factory oil pan before beginning stud installation.\u003c\/li\u003e\n\u003cli\u003eClean all old gasket material and sealing compound from the block oil pan rail and pan mating surface.\u003c\/li\u003e\n\u003cli\u003eApply thread locker or anti-seize to the stud-end threads of each MOR38948 stud per Moroso's recommendation.\u003c\/li\u003e\n\u003cli\u003eThread each stud into the block hand-tight, then tighten to the specified torque using a stud-setting tool or double-nut method.\u003c\/li\u003e\n\u003cli\u003ePosition the Moroso 20948 oil pan and gasket or sealant onto the studs.\u003c\/li\u003e\n\u003cli\u003eInstall all nuts finger-tight, then torque to the factory oil pan specification in a crisscross pattern.\u003c\/li\u003e\n\u003cli\u003eRefill the engine with fresh oil and check for leaks after startup.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
