This is an optional X Factory "Infinity" Associated B5M Chassis Stiffener Set. The Infinity Side Stiffeners are a set of plastic pieces that fit your B5M Infinity chassis (XFCI105), mounting between the main chassis plate and the side decks to provide torsional rigidity and help improve consistency. These parts weigh in at less than 10 grams, helping to maintain the significant weight savings of the carbon fiber chassis kit. They fit perfectly, using existing holes for mounting, while still allowing easy and quick flex adjustments.

As an additional benefit, they provide a convenient mounting location for Velcro, making it easier to attach your body to the chassis.


  • Adds torsional rigidity to your Infinity B5m Chassis
  • Maintains the lightweight nature of the CF chassis - the stiffeners weigh less than 10 grams
  • Adds chassis flex - aluminum chassis is too stiff for most off-road racing
  • Great Velcro location for mounting the body more securely
