69 Roadrunner Protouring
 

I have completely gotten out of my element and purchased a 69 Plymouth Roadrunner. Just an itch I have always wanted to scratch!

It seems that the only 3 companies I can find that make PT suspensions for it are, RMS (Alter-k-Tion), XV motorsports, and Hotchkis. I fully realize there are not nearly as many available products as there are for a Chevrolet, but I wanted to make sure that I did not leave anyone out of my search.

Thanks,
Chuck

magnum force also

I hope this will help. I will start with what in my opion is the worst system out there. Magnum Force. This system uses your stock shock mounts and this will cause the inner fenders to move in and close the hood gap. If not keeping the hood from opening. There are plenty of guys you can find on the web that have had and removed these.
Now XV. looks like a very good system. The only down side I can think of is it takes alot of work to install. This would be my second choice.
RMS (Alterkation), I am a little partial to this system. I own one. This system is a complete bolt in system. Very easy to install and lots of adjustment. You can find plenty of very fast and highend cars using this. Most of the Mopars on the Powertour that have a aftermarket suspenion came from RMS. This is just my two cents.

A stock type system like Hotchkis is very capable.

The fabbed K-members show a lot of extra benefit to someone doing motor swaps in an smaller A-body like a big block or a modern Gen3 hemi. Even a Gen3 Hemi in B-body (Road Runner) my be an issue with a stock K-member, beyond just motor mount adapters.

+1 . Set up right, it can run with the best of them.

Upgrade the stock or go with the AlterK. I went AlterK for ease of fitting headers etc....as well as some weight savings (95lbs ish)

Look around and you may find pics of failed aftermarket systems out there, BUT I have never seen or heard of an AlterK failing

I have one major beef with the alterk.. and that is their solution to bumpsteer correction, and to a lesser degree their choice of non greasable, non sealed heim for suspension bushings..

The issue i have is that instead of using a tall steering joint they went the cheap and unsafe route of elimination the conical steering joint/spindle and replaces it with a spacer tube and a single sheer joint.. and its only held together by the friction from tightenig the thru-bolt... once it slips once it will rattle loose

you just dont use single sheer conections and nylock bolts in a critical application like that, atleast not on a road car that doesnt get inspected every weekend before a race.....

and i dont care what pictures you have or havent seen.. its not a roadworthy solution especially since they could have steering jounts made from howe in the height they needed and done away with that all thoegter

The Heims as suspension joints are awesome the first time you take them out.. but they are non sealed and wear fast... so for a street car its not my cup of tea, but atleast its double sheer mounted.. its just a cheap solution that is inferior to so much else available at fractionally higher cost...

enough with the rambling, check the pic below to see what im talking about

Deuce,

I challenge you to find a failed Alterkation. These are on Autocross, Street, and Drag cars all over the wold. They are very strong and yes they are greaseable. I have had one for over 8 years. They have been on every powertour sence 2003.

My uppers are polybushed, not heims..........from RMS

AlterK's have been mentioned with over 60,000 street miles on them now without reported issues. On this forum pics of OTHER companies system's have been posted showing catastrophic failures and we are not on one of the crazy "mopar or no car" sites

i have a bigger challenge.. read my post!

Ill admit i stand corrected in the greasability BUT im not talking about pictures of failed stuff.. im talking about the right and wrong way of engineering stuff.. and spacertubes, threadad rods with nylocks and single sheer joints have no place in the steering on a roadworthy car... It could have beed solved with a tall rebuildable howe steering joint

but it may however well be the best aftermarket suspension out there for a mopar, and im happy you like yours....
