Clean, factory-style routing:Lines follow the factory e-brake cable path and connect to your factory rear caliper hose connections in the rear wheel wells
Bulkhead firewall connection:Keeps your install neat, secure, and professional
All-inclusive kit:All lines, tees, and fittings included—no extra trips to the parts store
Custom style:Made to order in your choice of color combo for a personalized touch
Premium construction:PTFE core, stainless braided covering, and a poly outer coating for abrasion resistance and long-lasting performance
