JetManiac's Midshaft Shop
JetManiac has new and used midshafts (aka: intermediate shaft), housings, couplers, and parts for your SuperJet or aftermarket hull build or rebuilds. Also for your Waveblaster and FX-1.
Send us your tired midshaft assembly for repair/replacement/rebuild OR select from our components and have one custom built to your spec. We have built hundreds of midshafts and know how to build them properly.
Otherwise we can provide you with all of the parts necessary to build or rebuild a midshaft assembly yourself.
