There’s no shortage of fun watching Ultra4 racing grow, and pushing the boundaries of what is possible at each and every race is standard practice these days. On the constant quest of getting everything you can out of the tight space of a race vehicle, we are excited to release our IFS 4130 Narrow Width Housing. With a modified Gearworks HP 10″ third member (sold separately), we are able to tighten up the CV flange to CV flange by 1.4″. For the right builds, this allows those mid-shafts to be longer and the suspension & steering to travel more. Available today at http://www.spidertrax.com/IFS-4130-Narrow-Width-Housing .
