    Using Rancho 4\" lift front springs?

    Well, I finally took my truck out this weekend to see what I've got (just bought someone elses incomplete project). I have to say, I'm really disapointed with the Front Rancho springs. Just after getting the motor in on Saturday, I ran it up my street for a test run and over a few speed bumps. Now granted that I didn't have any shocks on it yet ( missing item at purchase) so I expected some bounce. What I didn't expect was what looked like a monster truck freestyle event from the curb(and of course, every subsequent bounce after that). My front end might as well be welded to the axle its so stiff. I'm heading out to get a set of shocks now (I'm half tempted to throw a set of RS5000's on there just to compliment the stiffness of the spring). Anyone running a Rancho 4" front lift with a decent riding shock?

    Rancho makes at least two 4" leaf springs. One is the soft ride 86206
    the other is Heavy Duty, and I think has an "S" in the part #.
    If you have the H.D. Put a Winch, and heavy bumper up front to pre-load the springs.
    Good luck

    Re: Using Rancho 4\" lift front springs?

    I'm running 4" Rancho springs with 4 Dick Cepeck shocks and you are right--THEY ARE STIFF!!! I always joke that my truck feels like I'm driving a horse carriage with wooden wheels on a cobblestone street. OUCH! But seriously, they are very, very stiff. The good thing about them is they don't sag and last a pretty long time, which is a major plus in my book.

    I'll tell you what REALLY improved my ride. I replaced all the body mounts when I installed my body lift, and I could really tell a huge difference in the ride quality. I couldn't believe it, and that's because mine old rubber mounts weren't too bad (at least that's what I thought). Check out your body mounts.

    Yep, Executioner hit the nail on the head with Rancho and their two-part-numbers of front springs. The 86206 is the softer-riding spring and the 40054S springs are the firmer riding ones.

    Re: Using Rancho 4

    Well, I ended up getting a set of Pro-Comp ES3000's and they did a good job of dampening the Rancho 86206 (no S) 4" front springs and an even better job on the stock rear leafs. Muddysub, can you tell me a bit more about your front axle, tires, motor so I can size them up on how they might perform on mine. Thanks again to everyone who posted, its good to know what people are using and how they feel about it.

    Re: Using Rancho 4

    I have the Rancho soft ride set and my truck rides better than any lifted straight axle truck I've ever rode in. I have a SWB K10.

    I put a set of used 4" Rancho's on my Blazer, and they are as nice as the stock springs. I expected a bad ride, but they ride nice. Maybe because they were broke-in when I got them.

    Re: Using Rancho 4

    Well, now that I've got some shocks on there... I'm going to go "break" these Rancho's in one way or another. What I really need is a long parking lot with a lot of cement curbs all lined up in row. I'll just keep making high speed passes with a couple bags of cement on the hood, its bound to soften up sooner or later.

    Re: Using Rancho 4\" lift front springs?

    One thing to also consider in ride quality (which is overlooked by many) is your tire size. Keep in mind that the larger the tire, the "softer" the ride. Even though its a rough ride now, it is much better with the 36" Swampers I run now compared to the 33" BFGs I used to have on it.

    Re: Using Rancho 4

    Do you have any pics of your truck that shows a side view with your 36's? I'm still trying to make up my mind on how much tire / lift I'm going to be happy with (all this sand out here and such). I like the look of the 39.5 MT Baja Belted, but thats a lot of tire / lift or fender cutting.

    Re: Using Rancho 4

    Borrego, here is a link to my pics. The first one is with the 4" Rancho lift and the second link is the 4" Rancho along with a 3" body lift:

    http://briefcase.yahoo.com/bc/mando_alvarez/vwp?.dir=/My+K5&amp;.dnm=7+inches+of+total+lift.jpg&amp;.src=bc&amp;.view=l&amp;.done=http%3a//briefcase.yahoo.com/bc/mando_alvarez/lst%3f%26.dir=/My%2bK5%26.src=bc%26.view=l

    Unless you plan on doing some significant fender trimming, I would NOT recommend running 36" tires with just 4" of lift, especially if you will be running in the sand. My tires rubbed on the fenders just on the street. The 7" of lift is perfect in my opinion for the 36" tires, but I don't know how you feel about body lifts. I would have loved to go all suspension lift but do not want to struggle with driveline vibration anymore than I have to. I will eventually install a 6" lift. If you have anymore questions or would like more pics, let me know.
