This BDS 6" long arm conversion kit maximizes the capability of your 2003-2007 Ram 2500/3500 4WD diesel, with clearance for up to 37" tires. Up front it runs FOX 2.5 remote-reservoir coil-overs, all four control arms plus mounting brackets, a forged drop pitman arm and track bar bracket for steering correction, bump stops and sway bar links. The long-arm upgrade uses massive 1/4" steel frame brackets and oversized formed upper and lower arms (greaseable polyurethane bushings) to add strength, reduce caster change through travel, and improve offroad articulation. The rear uses heavy duty cast steel blocks, longer u-bolts and matching FOX 2.0 Performance shocks.

Great replacement kit
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.
