Smooth Rider
Afternoon everyone,
I have a 1997 4Runner and I am looking at smoothing out it's road manners. This truck is very stiff and seems to rock the whole truck on every single bump in the road. Does any one have any sugestions to calm it down, i.e. different set of springs (890, 905) I really dont know what those numbers mean. I can only guess that they designate the spring rate on each spring where the higher the number the higher the spring rate? Any help would be appreciated. Thanks again.
Bruce

I'm going to say that those numbers are part numbers.
Usually they help you get the right spring when buying OEM replacements from the dealer, at least in my exp.
Maybe some new shocks might help the ride?

I doubt it, When I bought mine the ride was really rough and thought that putting new shocks on would smooth it out. Granted I put on Skyjacker Nitro shocks which aren't suppose to really provide an ultra smooth ride but to be honest I could really tell no difference at all. I'm hoping that when I put new springs on that it will help a little but honestly I doubt it.
On a car I used to own I had the same problem and only when I switched to Bridgestone Potenzas which use a very soft compound did I finally get the smooth ride I hoped for.

Yeah, I know tires have a lot to do with it. Right now mine is the same way and I am running BFG/ATs and they are supposedly notorious for rough riding. I havnt replaced my springs yet, but plan to do that this weekend, but I'm not sure how that will make it any better because I'm putting on Old Man Emu 891s (much stiffer than stock) and the stock springs on there are bottoming out. So I dont see how the rough ride could be comming from the super soft springs. I know they are allowing for a bunch of body roll that I can hopefully eliminate. But hopefully some higher quality shocks will damp out the motion better.

Well I just put a fresh set of Monroe SensaTrac shocks on front and rear. Yes, the shocks did settle it down quite a bit but they just eased the shock of the bumps not really making it so that you almost dont feel it. As for the air pressure I run 36 in the front and 35 in the rear and for tires I am running some road tires made by Dunlop, not mud tires at all. Does anyone know what spring number is supposed to be the softest?

36 and 35 pounds, that'll do it. I'm sure that helps the mileage on the hwy....
Air down a few psi, and things will soften up nicely. That much air and your making your tires harder and harder, and they cant absorb the shock, you may have to reach a fine line of comfort vs. gas mileage.

What tire pressure do you recomend?
I dont know if I am or not but my front or rear, the truck really doesnt dip that much. How much travel does it take to bottom out against the stops? Is it wise to shorten the bumpstops? or remove them? Thanks for you help, I'll be back tomorrow. Time to go home
