A new Major Rebuild Kit for Fontaine fifth wheel models combines six kits into one. The Major Rebuild Kit (P/N KIT-RX-67NTL) includes parts required to service all left-hand 6000, 7000, 7000 Clean Connect and Ultra NT top plates and supports Fontaine’s No-Slack II lock technology. The box includes disassembly and reassembly instructions and contents packaged in sequence. A QR code printed in the kit links to an instructional video about the rebuild procedure.
