The 40in Steel Fenderwells from Competition Engineering are purpose-built wheel tubs designed for serious street and strip builders who need reliable clearance for larger tire-and-wheel packages. These fenderwells are ideal for those installing oversized slicks for drag racing or upgrading to modern performance wheels on classic platforms.
Manufactured from 24-gauge steel with a beaded construction for added rigidity, the 40in Steel Fenderwells deliver both strength and light weight—critical when every pound matters in performance builds. The beading process cold-forms the metal into reinforcing ribs, dramatically increasing torsional stiffness without adding bulk or compromising fitment.
These fenderwells accommodate substantial wheel-and-tire combinations while maintaining proper suspension geometry and brake access. The natural (uncoated) finish allows you to integrate these into your build using your choice of welding, epoxy, or mechanical fastening, and permits custom finishing to match your vehicle's interior or underbody treatment.
