It is engineered to fit 1.125\" crankshaft applications across many Exmark Lazer Z series, Next Lazer, Pioneer, Quest, Vertex, and compatible Toro Z Master and Turbo Force models. The design emphasizes durability, reduced belt wear, and simplified maintenance by allowing bearing replacement using the integrated snap ring.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this clutch improve durability compared to OEM units?\u003c\/h3\u003e\n\u003cp\u003eThe BIGBearing HiTorq clutch uses a larger pulley bearing and premium C3-clearance bearings that tolerate higher temperatures and side loads.

It suits anyone who wants higher torque to prevent slippage, a pulley built to reduce belt wear, and the option to service the bearing rather than replace the entire pulley assembly. If you run large properties, commercial contracts, or simply want longer clutch life and easier maintenance, this HD Switch BIGBearing HiTorq clutch is engineered to meet those needs—confirm model and serial compatibility before ordering and contact Tech Support with questions.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this clutch fit a 1.125\" crankshaft?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
