3D Pro Carbon Flexible Anti Tuck Body Stiffener for Horizontal Rear Post Body Mounts Pro

Introducing our 3D Pro Carbon Ultra-Lite Flexible Anti-Tuck Stiffener Set for Horizontal Rear Post Body Mounts Pro

How good is hard close racing... until you get a body tuck. Make body tucks a thing of the past with our new ultra lightweight, durable solution! 

These rear fender stiffeners combine very thin carbon rods with the latest 3D Printing technology to provide a feather weight of only 1g each! The best part... they attach directly to our Horizontal Rear Post Body Mounts Pro! Simply screw them in underneath into the spare hole in the HRP Pro, install the double sided tape dots, and remove the adhesive film. Attach to the rear fender, at least a few millimetres away from the wheel arch.

These are particularly handy these days with lighter bodies, and bodies being mounted further forward which leaves such a small amount of material behind the rear wheel arch. This material is often very flexible and can very easily get tucked up under the rear wheel. 

The plastic parts are printed at a very high resolution and with some of the highest quality filaments on the market to make them fit for the task. The bottom part is printed from a flexible material which exerts less pressure on the shaft in a crash, as well as conforming to the body whilst seamlessly attaching with the supplied tape.

They work with all bodies equipped with our Horizontal Rear Post Body Mounts Pro!
