Manufactured by Energy Suspension, this mount uses the company's Hyper-Flex polyurethane formulation to resist oil, road salts, and other contaminants that commonly degrade rubber mounts. It is designed for durable, long-lasting service while maintaining the correct alignment and isolation for transmission components.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 3.1108R improve drivetrain stability?\u003c\/h3\u003e\n\n\u003cp\u003eThe polyurethane body of the 3.1108R is firmer than stock rubber, reducing unwanted motion under acceleration and shift events. That translates into crisper transmission feel and less strain on related hardware. The more consistent material properties also help maintain alignment over time.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHyper-Flex polyurethane resists permanent compression and retains shape.\u003c\/li\u003e\n  \u003cli\u003eReduces engine\/transmission movement during load changes.\u003c\/li\u003e\n  \u003cli\u003eHelps prevent premature wear on driveline brackets and bolts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this mount fit my GM vehicle and how direct is the replacement?\u003c\/h3\u003e\n\n\u003cp\u003eThe 3.1108R is built as a direct replacement for compatible GM transmission mounts, matching bolt patterns and overall dimensions for straightforward swap-in installation. Always check vehicle fitment lists or compare with the removed mount to confirm compatibility. Installation typically uses existing hardware and factory mounting points.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDesigned to mirror OEM mounting locations and bolt holes.\u003c\/li\u003e\n  \u003cli\u003eNo custom fabrication required when matched to correct GM model years.\u003c\/li\u003e\n  \u003cli\u003eWorks with standard tools for most DIY installs or by a professional mechanic.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does Hyper-Flex polyurethane handle contaminants and temperature?\u003c\/h3\u003e\n\n\u003cp\u003eEnergy Suspension's Hyper-Flex formulation is engineered to withstand oils, greases, road salts, and ozone that commonly break down rubber components. It also resists permanent compression, so the mount maintains its damping and support characteristics across temperature swings. This means longer service life in typical driving environments.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eChemical resistance reduces swelling and softening from fluids.\u003c\/li\u003e\n  \u003cli\u003eLess prone to cracking from ozone and UV exposure than rubber.\u003c\/li\u003e\n  \u003cli\u003eMaintains load-bearing shape under repeated thermal cycles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat should I expect during installation and routine maintenance?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation of the 3.1108R follows standard transmission mount replacement procedures: support the transmission, remove the old mount, position the new unit, and torque bolts to factory specs. No special adhesives or modifications are required. Routine maintenance is minimal — periodic visual inspections for secure fasteners and surface damage are typically sufficient.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eUse a transmission jack or lift to safely support the drivetrain.\u003c\/li\u003e\n  \u003cli\u003eTorque bolts to manufacturer-specified values to prevent loosening.\u003c\/li\u003e\n  \u003cli\u003eInspect for fluid leaks that could contact the mount and address leaks promptly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Energy Suspension 3.1108R is ideal for GM owners and technicians seeking a longer-lasting replacement for a worn or failing transmission mount. It's well-suited for drivers who want improved stability over aging rubber mounts, performance-minded enthusiasts seeking firmer drivetrain control, and professional shops looking for a reliable, OEM-compatible polyurethane option. If you require a direct-fit mount that stands up to contaminants and repeated loads, the 3.1108R is designed to meet those needs without altering vehicle geometry.\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: Is the 3.1108R a direct replacement for GM transmission mounts?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, the 3.1108R is designed as a direct-fit replacement for compatible GM mounts, matching factory bolt patterns and mounting points.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the polyurethane resist oil and road contaminants?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, Energy Suspension's Hyper-Flex polyurethane resists oils, road salts, and other contaminants better than standard rubber.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Energy Suspension","offers":[{"title":"Default Title","offer_id":48084033667230,"sku":"B000CNAXDO","price":70.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/energy-suspension-3.1108r-front-view.jpg?v=1785844252","url":"https:\/\/northtrailauto.ca\/products\/energy-suspension-transmission-mount-for-gm-3-1108r-polyurethane-direct-fit-hyper-flex-durability","provider":"North Trail Auto","version":"1.0","type":"link"}
