Relations Racing Rock sliders

Please do! It'd be nice to have some actual numbers to help cut through the marketing wank.

 

That’s a pretty sweet design! My sliders are from OPOR and sound very similar except wrapping around the frame. That’s a real nice added feature.

 

Yes, but with sliders we are operating well below the yield point of the steel. It's really an exercise is limiting deflection. It does no good to allow the sliders to flex and hit the rocker panel under a hard hit even if they don't permanently deform. In this case, it's a beam bending problem and yield strength is not a factor, only the modulus of elasticity and area moment of inertia.

 

Oh yeah, I don't disagree at all. I would be curious to know where do you see failure in your engineering models, though. I'm guessing at the bolt to frame moment connection?

 

We don't really see a failure in the classical sense. Really we are just pinpointing where the majority of the deflection is occurring. We identified two main contributors. The main tube under the pinch seam, particularly the rear most portion in front of the rear wheel. This is where it is typically the least supported. Also, for bolt on sliders, the mount plate is a main contributor to the overall deflection of the sliders. The load path from where the support legs meet the plate to where the load is transmitted to the frame needs to be managed. This is less than trivial if you want to only use factory frame holes because they aren't positioned in a matter to help with this issue. There aren't enough factory holes close to the support legs to keep the plate from flexing under load.
