Brand new in boxes as pictured. Bought kit then sold boat prior to installing it. 530 new so save some money This is a great disc brake set manufactured by Kodiak. This is one of their 5 bolt 3500lb capacity disc brake kits. This particular brake kit has Dacromet rotors and mounting brackets and is paired with DACROMET calipers. This is Kodiak's part # 2/RCM-10-DAC. This kit is designed to fit on 3500lb capacity axles using the standard 4 bolt brake flange. This trailer disc brake kit will fit with 14 inch or larger wheels. This slip-on style rotor is great because your hub and rotor are separate pieces. Which means you can replace them independently of each other. This means if you get broken down on the side of the road because of a bearing failure you can replace your broken hub that are commonly available and still re-use your Kodiak rotor. You must have 14" or larger wheels to use with this kit. Using Kodiak's slip on brake set will add about a 1/2" of overall length to your axle. This means that your tires and wheels will sit about 1/4" out further on each side. Kit Includes: (2) Dacromet coated 10 inch vented rotors. The vented rotors help dissipate heat quickly. (2) Dacromet coated caliper mounting brackets. (2) Calipers that are DACROMET COATED inside and out except for the brass fittings where your brake lines run in. The brake pads are red steel backed. (4) Stainless Steel caliper mounting bolts. (1) installation/instruction manual is also provided.
