220-8422 Wilwood Flexline Kit for Front Caliber and Sunfire Drop-in

Internal hose degradation from environmental exposure, repeated flexing, and age can cause pressure drops, uneven caliper response, and internal fluid leaks, compromising braking performance and safety. This Wilwood Flexline Kit for front calipers and Sunfire applications provides a robust, high-quality replacement that restores hydraulic integrity and eliminates volumetric expansion during heavy-duty braking.

Constructed with heavy-duty materials and high burst pressure ratings, these lines are engineered for severe-duty commercial fleet use, ensuring reliable operation under demanding conditions. The kit drops directly into existing OEM setups, offering a drop-in upgrade that maintains optimal hydraulic response and minimizes the risk of line failure during intensive braking events.

Expert Installation & Field Note

Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of routing hoses to prevent chassis chaffing and ensure twist clearance during full-lock steering cycles. Always verify the mounting brackets on heavy commercial frames to avoid stress points and ensure long-term durability. Proper routing and secure mounting are critical to maintaining hydraulic integrity and safety under severe operational conditions.

Before ordering, physically inspect your existing line length, banjos, or flare fitting threads. Mid-year production changes and wheelbase variations often alter line routing on fleet and utility vehicles. Confirm all dimensions and fittings match your current setup to ensure proper fit and function.
