I have an 06 RAM 1500 HEMI 4x4 with a wicked shimmy from 65-75 mph. I've had new tires put on it, tires ballanced, rotated, caster adjusted, etc. all of which makes it a bit better for a while and it then gets progressively worse. It is usually worse while turning in one direction or the other.

I've been trying to get an aftermarket front steering stabilizer but, cannot find any past '05 due to the addition of the rack. Any suggestions? Does anyone else have this issue or a solution?

 

Do a search on the forum, unfortunately, it's a very common problem on the '06+ coil over front end trucks. Doesn't seem to be an issue on the '02-'05 torsion bar front models.
I've not seen a single company with a steering stabilizer for your truck and you are probably right, I'm sure it's because of the rack.

Again, use the search function and see how others with the problem have gone about solving or at least trying to solve the problem...

 

I'm going to call fox shocks on monday because it says on 4 wheel parts that they have one but its probaly for the mega cab.

 

Why are you looking into a steering stabilizer? The last post I read of yours regarding your shimmy said it was 100% a thing of the past.

 

Have the driveshaft balanced or replaced
