This kit allows you to replace the fusible links that normally protect the main power feeds from the battery and alternator with Maxi-Fuses. Perfect for rewiring jobs. Maxi fuses are easy to detect, easy to replace fuses. Our kit has 2 maxi-fuse holders with 8 ga. wire leads and waterproof covers, (3)-50 amp maxi fuses plus connectors and tie wraps. Also use for any high amperage add-on circuits. NOTE: Maxi fuses are not slow burn like fusible links.
