{"product_id":"water-pump-coupling","title":"GM Water Pump Drive Shaft Coupling","description":"\u003cp class=\"PDq2pG_selectionAnchorContainer\"\u003eThe water pump drive shaft coupling connects the cam-driven water pump drive to the water pump on L99, LT1, and LT4 engines. This genuine GM replacement is a good replacement for an original coupling that is worn, damaged, corroded, or otherwise questionable.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eBecause proper fit and function are important in this application, we recommend inspecting the coupling whenever the water pump is removed or replaced. O-rings should also be replaced during service. Worn or damaged O-rings can allow moisture and debris into this area, leading to corrosion of the coupling and splines and making future removal or installation more difficult.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy we use the GM coupling:\u003c\/strong\u003e We’ve tested several lower-cost aftermarket equivalents sold online in an effort to find a more affordable option for our customers. Unfortunately, the versions we tested had fitment issues, with some fitting poorly and others not fitting properly at all. For that reason, we continue to use the genuine GM 10128334 coupling.\u003c\/p\u003e","brand":"General Motors","offers":[{"title":"Default Title","offer_id":45153576452296,"sku":null,"price":92.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/8378\/files\/water_pump_coupling_lt1_lt4_l99.png?v=1787241548","url":"https:\/\/throwbackautomotive.com\/products\/water-pump-coupling","provider":"Throwback Automotive","version":"1.0","type":"link"}
