TBM Rear Brake Line Kit TB-FBK18-B for Dodge Challenger Hellcat & Gen 3 HEMI TBM Rear Brake Conversion

Complete your TBM rear brake conversion with the TB-FBK18-B Rear Brake Line Kit, engineered for Dodge Challenger Hellcat applications and other Gen 3 HEMI builds using a TBM rear brake package. This kit is specifically intended to be used with TBM Brakes part number 001-0309-1, making it the correct supporting component for a properly matched rear brake setup. When upgrading to a lightweight drag brake system, the brake lines are just as important as the calipers and rotors, because proper hydraulic routing directly affects pedal feel, consistency, and overall system reliability. This kit is designed to provide a clean, application-specific solution that helps ensure dependable brake fluid delivery while supporting the performance demands of high-horsepower street cars and dedicated race vehicles. If you are building a Challenger for the strip or refining a serious Gen 3 HEMI setup, the TB-FBK18-B kit is the finishing component that helps tie the system together.

TBM Brakes is known for lightweight braking solutions that help racers reduce unnecessary weight without sacrificing control, and this rear brake line kit follows that same philosophy. The TB-FBK18-B part number is intended to work with TBM rear brake conversions, eliminating the guesswork that often comes with adapting factory hoses to aftermarket brake components. By using application-specific line lengths and fittings, the kit helps simplify installation while maintaining proper routing and dependable hydraulic performance under repeated hard braking conditions. That means less time modifying parts and more time focusing on performance, consistency, and confidence at the track.

One of the biggest advantages of using a dedicated brake line kit is reliability. Factory brake hoses are not always ideal for drag racing brake conversions, especially when the vehicle has been modified for weight reduction, suspension changes, or wheel and tire upgrades. The TB-FBK18-B rear brake line kit helps reduce stress on the hoses and fittings by providing a purpose-built solution designed for the demands of performance use. Proper fitment can help minimize the risk of leaks, abrasion, and premature wear, while also making future service and maintenance easier for owners who regularly inspect or adjust their chassis setup.

For Gen 3 HEMI enthusiasts, this kit is especially valuable because lightweight rear brake packages have become a popular upgrade for Hellcat, Demon, and other Challenger builds seeking improved launch consistency and reduced unsprung weight. Whether your car is a street-driven performance machine or a purpose-built drag car, pairing your TBM rear brake conversion with the correct brake line kit helps ensure the entire system functions as intended. The result is a cleaner installation, more predictable braking behavior, and the confidence to make repeatable passes with a properly engineered setup.

If you are upgrading your Challenger with TBM rear brakes, the TB-FBK18-B Rear Brake Line Kit delivers the fitment, durability, and performance support serious Gen 3 HEMI owners expect.
