The rod is longer than it needs to be. It only needs to be long enough for the set screw collar to tighten down upon it, and it can also be pre-loaded slightly before tightening it down.

If a fuselage reinforcement collar on the front gear is not enough, and you're still bending the rod, there's still things that can be done... Shortening of the rod and pre-loading the suspension as described will reduce the lever length of the landing gear. Also, after a crash, the foam can become squished so that the landing gear is no longer angled forward sufficiently. This forward slant is important because it transforms frontal impact (wheel running over bumps and stones) into vertical suspension travel. If the landing gear has defomed into a near-vertical shape, all of these small bumps will become lateral forces that will continue to deform the foam and bend the rod backward.

Also, you can the strengthen the fuselage against deformation by making the reinforcement collar part of a broad platic plate which is glued across an area of the fue, perhaps 2" x 3". I did this on my jet and it worked well.
