The Dana & Chrysler Rear Disc Brake Conversion Kit is part of the TeraFlex lineup for keeping a lifted, heavier Jeep stopping safely. It addresses the extra stopping demands that come with larger, heavier wheel and tire packages. Part number 4354420 fits the 1991-2006 Jeep Wrangler.
Not Included:
Brake fluid, wheels, emergency brake cables and installation labor are not included unless the listing names them.
Features
Made for lifted, heavier Jeeps
Each part is aimed at the braking and clearance problems that appear once a Jeep carries a lift, bigger tires or extra gear.
Keeps lines clear through travel
Longer lines, anchors and spacers keep brake lines, sensor wires and cables clear of the tires and suspension at full travel.
Bolt-on to factory mounting points
Most parts bolt to existing mounting points with hand tools, and the instructions call out any trimming or bleeding the job needs.
Serviceable with TeraFlex replacements
Replacement pads and anchors are available from TeraFlex, so the system can be maintained as parts wear.

About TeraFlex
TeraFlex is a Jeep company at heart, started and staffed by people who drive them. It designs, engineers and builds suspension systems, shocks, axles and performance parts, with the Wrangler and Gladiator at the center of the lineup.
The company traces its history to the 1950s, when it began as MEPCO (Military Equipment Parts Company), one of the first companies anywhere to supply Jeep parts and accessories. TeraFlex Manufacturing followed in 1996 to build heavy-duty suspension for the TJ Wrangler, and the brand credits itself with the first suspension system for that coil-spring platform, a low-range gearing option for the 231 transfer case and the CRD60 high-pinion axle.
The current catalog covers full lift systems, the Falcon shock line and a long list of Wrangler and Gladiator upgrades, and the company is now carrying the same engineering approach to other vehicles as well.
