When subjected to continuous demand from dual electric cooling fans, air conditioning compressors, upgraded stereos, or modern electrical conversions, factory units experience heavy thermal soak inside the cramped \u003cstrong\u003eLT1\u003c\/strong\u003e engine bay. Excessive heat causes internal bridge rectifiers to degrade, inducing severe voltage sag at idle speeds (below 800 RPM) and premature diode burnout.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 300-amp unit features precision heavy-gauge copper windings and high-temperature insulation to resist thermal saturation. Engineered with an upgraded heavy-duty internal rectifier, high-amperage avalanche diodes, and efficient rotor balancing, it supplies consistent 14.4-volt power even in low-RPM traffic conditions. Housed in a cast aluminum casing designed for direct bolt-on installation, this unit replaces failure-prone OEM equipment—such as \u003cstrong\u003e10463338\u003c\/strong\u003e and \u003cstrong\u003e10480201\u003c\/strong\u003e—without mounting bracket modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 300-Amp High Output Alternator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1994-1996 Buick Roadmaster\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e5.7L LT1 V8 \/ GM B-Body\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e260 hp \/ 330 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e10463338, 10463678, 10480201, 321-1111, 321-594, 334-2401, AL8691X, 210-5183, 8112-5, 8112N, 8112-5N, 8112N-5, 8112N-300A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1994 Buick Roadmaster Sedan \/ Estate Wagon 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e1995 Buick Roadmaster Sedan \/ Estate Wagon 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e1996 Buick Roadmaster Sedan \/ Estate Wagon 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the B-Body Roadmaster?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1994-1996 Buick Roadmaster equipped with the \u003cstrong\u003eLT1\u003c\/strong\u003e 5.7L V8 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my main power wiring?\u003c\/h4\u003e\n\u003cp\u003eA 1\/0 AWG Big Three wiring upgrade is strongly advised to support 300-amp throughput and prevent excessive circuit resistance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Buick LT1 Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle high-output demands on GM full-size pushrod V8 platforms, this alternator ensures rock-solid electrical integrity under high thermal and mechanical stress.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67566198325496,"sku":"DS-EK4DFKRQP","price":397.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-buick-roadmaster-1994-1996-5-7l-1.jpg?v=1791084430","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-buick-roadmaster-1994-1996-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
