Spidertrax Series 30 Builder Bells 4130 Chromoly
Our IFS Series 30 Builder Bells are the perfect platform for fabricating the best Ultra4 upright. Manufactured in 1 piece out of billet (yes, billet) 4130 domestic grade chromoly steel, they offer not only flexibility in upright design but the ability to fully heat treat your uprights post-welding. It's one of the only builder bells on the market that allows for post heat treating, and with the direction Ultra4 is taking, it is highly recommended that you heat treat your uprights. The IFS 30 Series Builder Bells are sold as a pair, and accommodate Spidertrax 30 Series Stub Shafts & Spidertrax Ultimate Unit Bearings (hardware to assemble Ultimate Unit Bearings included with our builder bells).
