taller shackles ?

I have a stock Samuria and I'm wanting to soften the ride up some while not spending much money. I see on Rocky Road's web site that they say their longer than factory shackles will help soften the ride. Is this true and does it help enough to notice ? Is there any negatives against using longer shackles like poor handling on the road or anything ?

Re: taller shackles ?

Not sure from experience about the longer shackles softening the ride. Always changed more that just the shackles with every suspension mod I did.

From this page you can see that if the angle of the shackle in relation to the spring widens, the spring rate will appear softer.

Some negatives:

Pinion angle will change, may cause some vibration.

You might have more side to side movement as well, depending on the type and length of the shackle. I think the type with the cross bar in the middle reduce this.

Re: taller shackles ?

The worst thing about longer shackles is they take the castor out of the front axle, which will lead to the
vehicle wandering instead of tracking properly. Not advised. Not all of RRO's web comments are apropriate,
just sellers hype.

Re: taller shackles ?

Thanks for the replies. I guess I want be doing the longer shackle thing. Is there anything that can be done to soften the ride without changing out the springs ?

Re: taller shackles ?

Make sure you aren't running too much air pressure in your tires. I don't know what size tires you have, but try running about 20 lbs instead of the 30 or so people seem to end up with for whatever reason. Very high pressure makes the choppy, hard ride even worse.

I have YJs and Racho 9000x shocks on my samurai and I LOVE the way it rides. I love it so much that I decided to turn back towards making the samurai a street truck. [img]images/graemlins/smile.gif[/img]

Re: taller shackles ?

I'm currently running 20 pounds in the tires.
What's all involved with changing over to YJ springs ?

Re: taller shackles ?

For YJs you need to get the mounting hardware since the springs are 1/2 wider than samurai springs and quite a bit longer. It is easier to run stock sami springs in the front and put in Jeep CJ springs in the rear since they are the same width.

Check out vendor sites like Trailtough.com, northcoastoffroad.com, petroworks.com and rocky-road.com. Most all of them sell stuff to adapt the springs to a sami in kits form and also separately. You can see how much it costs that way. Most of the solutions are bolt on, as I recall.
