Construction & Design

The hoses in this kit are crafted from premium-grade silicone, known for its flexibility, durability, and resistance to heat and pressure. Unlike traditional rubber hoses, silicone maintains its integrity under extreme conditions without becoming brittle or softening. This ensures consistent coolant and transmission fluid flow, reducing the risk of leaks or hose failure.

Each hose is paired with stainless steel embossed clamps that provide a secure, non-damaging grip. These clamps are designed to avoid cutting into the silicone, extending the lifespan of the hoses and maintaining a tight seal even under vibration and thermal expansion.
