  • 【Improved Flow and Cooling】With a 1/2" ID compared to the factory's 3/8", it offers 33% more flow. This significant upgrade reduces transmission temperatures by 15-20°F, providing better cooling performance and protecting the transmission from overheating.
  • 【Professional Installation Advised】Due to rigid lines and specific routing, professional installation or advanced DIY experience is strongly recommended to ensure proper fit and avoid errors.
  • 【Construction】The kit features a heavy-duty transmission line upgrade. It eliminates plastic fittings, replacing them with all-metal connectors, and uses kink-free braided lines to prevent flow restriction. The AN-style fittings provide leak-proof seals, eliminating quick-connect failures.
  • 【Performance Benefits】By consistently cooling the transmission fluid under heavy loads, it extends the transmission's life. It also enhances the towing capacity by managing heat buildup during long hauls and protects the fluid integrity from thermal overload.
