I think that you will find that the resultant
longitudinal forces will only be 1000N.


I didn't use a 4000N input. I used a 100kg mass bashing into it at 40m/s. But yea those were the average forces at the supports.

Go back to the FBD to see if it should be 1000N or not. No point just making up numbers because they feel good. Also no point making up a 'law of conservation of magnitude of force' when none exists. This mechanism has a mechanical advantage or disadvantage, so you can tune it to give whatever horizontal force you want. You can have 1000N if you want, but it won't detract from the 4000N pushing backwards.
