Called around for quotes to get them replaced and everyone was quoting over $2k just for bellows. Figured I’d give it a try. The rubber is good quality and feels soft. Time will tell but this is an easy job if you’re mechanically inclined. Make sure you replace the plastic water pickup fitting while you’re at it. Found mine to be cracked on disassembly and had to wait for a new one. Should be a easy 3-4 hour job if your not doing the bearing and only doing bellows

Good value, very useful for go kart wiring

Size: 100ft, Style: 6C-18AWG

It's a good spool to have around to wire lights and things on the go karts. Also came in handy when I had to patch a bit of melted wire harness on the tail of the old Dodge.
