I run OME (coils and nitrocharger shocks) and am told I sometimes drive too fast on dirt (40-50 on washboard and thru wash whoops):dunno: of course I don't jump dunes.....

 

Monotubes will help out a lot. A reservoir shock will help out even more.

 

Teraflex speedbumps might be up your ally and better shocks for sure.

Was just about to say the same thing. Better coils too obviously.

 

Big difference between progressive vs linear coils for washboard stuff? Or no difference?

 

You dont NEED long arms and coilovers to do go fast.

You should get a good set of springs, some high quality remote resi shocks and some hydraulic bump stops. That will set you up to go fast.

 

x2 on that. It's hard to knock the benefits of long arms and coilovers, but you can get pretty far with shocks and short arms. No doubt.

 

Cool. So far that's what I'm concluding too.

Right now it's:
Synergy progressive springs - 3 inch

http://www.quadratec.com/products/16315_8002.htm
Blistein 5160 shocks with reservoirs

ProFender air bumps

Good bit of coin but still a far cry from coilover and long arms. Thanks for the input!

Now one last question:

AEV Geometry Correction Brackets...
http://www.quadratec.com/products/16502_4301.htm

Worth putting in or a waste of time for high speed/stability stuff?

 

I do very well on fast washboard roads and dunes with my short arm set up. I have the Rock Krawler 2.5 MaxTravel with RRD w/ remotes. Teraflex speed bumps, 35 inch Trail Grapplers, Poison Spyder flat flares and sleeved/ trussed/ gusseted front axle.

 

I have Bilstein 5160s. They tend to be on the stiffer side which is what I wanted in order to maintain really good on road manners. For fast offroading, you may want to look at some other options.

I know RK will custom valve a set for you and I have been hearing really good things about the Kings (but they are ridiculously expensive)\

Ask 2k2WranglerX about AEv

 

So you want a race jeep huh? on the cheap???? My old Tacoma had go fast suspension, and the truck fell apart around it after a year. (Read that sentence again...) Then I saved up and built my (now sold) 1994 Toyota truck the right way. Full cage, King C/O with bypasses and air bumps. It could do 50-60 in the whoops. Maybe faster, but that little 22re could only push it so fast.

I want my current jeep to do the same, but there is no way in hell a straight axle is gonna do 50 in the whoops without some KOH cash. Sorry Rancho, but your shock ain't gonna do it. WAJ... I spent a lot of time doing suspension tuning with slo-mo video, changing valve stacks and, and fluid weights to finally get the truck to ride smooth in whoops.

Your best bet is to soften the big hits out with either a bypass shock or high quality bump stops. Probably both. I even question how fast (and how long) you can drive a jeep with the double throwdown kit from Evo.

Just get the coils, a good shock, and bumps and enjoy the whoops at 25-30 mph.

Bypass is def another very good way to go but def ups the price a good deal because you also have to get some sort of upper mounting bracketry in there to make it happen.

I know Paul from Nemesis has that type of setup on his 2 door and it looks bad ass. Sadly, I havent had a ride in it :bawling:

 

TeraFlex Presents: JK PreRunner 2.0 Extended Version - YouTube

TeraFlex PreRunner kits typically are only a long arm version. However you can buy a short arm version or just the SpeedBumps/Fox shocks for what your trying to do.

 

I was reading somewhere that with lower ride heights ... say 3", the long arm really isn't that much of a benefit due to clearance issues.

I wonder how valid that statement is since I happen to have a 3.5" full short arm kit and very strong desire to not delete the exhaust loop on my 12 JKU (said to be almost a requirement to go long arm).

Since I do some light crawling (often with the OP), I value decent flex and I think I have it pretty good with my current kit (see my sig).

But I also run burmed logging roads and would like to find a solution that will let me throttle through a bit more.


Forgive my typos. I'm too lazy to proof read on a tiny iPhone screen

 

We are doing a similar set up on our Comanche build just installed a set of Synergy 4.5" front springs and Synergy lower control arms and track bar (on order).

Later will be getting a set of King 12" travel Reservoir shocks and airbumps and of coarse Synergy long arm in the front.

Now tell me if I am right or wrong but teraflex speed bumps is nothing more then foam in a can , so what is the real benifit for the price of them

 

Well its not foam its microcellular polyurethane

 

why profender?
Buy American!

Good question jaker!

 

ProFender is import? Ok that changes things...

 

I keep hearing good things about these cans, I myself am looking into getting these, but out of curiosity, what is the price of the profender ones?

 

Teraflex Speedbumps: $931 for a full set

ProFender: $139 per air bump, $26 per mounting can. Dunno if there's a rear version or not.

Kinda iffy on ProFender the more I think about it. Teraflex may be a more complete package and a cleaner install. Then there are the Fox air bumps too... Decisions decisions.

 

My $.02:

TF's from Quadratec for $875 - I'm sure you can get free shipping through some forum discount dileo.

$556= ($139*4) + another $104= ($26*4) in cans for mounting = $660

So another $215 to not have to hack your frame up and deal with welding?

If you're not going to do all the cutting and welding of doing coilovers, then why not?

Another thing: The TFs are made specifically for the JK (save variance between 2/4 door weight) in form and fit while the ProFenders seem to be universal.

Fox = same situation but more expensive.

Yea...decisions decisions

 

Teraflex needs to seriously drop the price of those, way overpriced IMO. If they would drop 2-300 Id be all over them.

 

x2 they are extremely high.

 

I think Teraflex is the only product that offers ease of installation. Not that I don't like to work on my Jeep. I worked on everything on it minus re-gear , sleeves/gussets and installing my rear TrueTrac... but with a life to get back to, the TF offering is almost worth the price of my time. Leaning heavily towards TF compared to generic cans. Plus, I don't see any of them offering rear air bumps. TF does.

 

First off stop comparing TF speed bumps to other bump stops , TF is foam just like what you got now and the day stars

Me even it was a little bit of a headache to install I would go with fox , king or something in the air or oil family and the plus to that is you can find them used cheap as crap ( go on pirate )

At the end of the day it is your money 1000 for foam or 1000 for oil or air

 

I dont think TF bump stops with foam material can compare in performance to a quality piston bump stop.

 

Im not sure from an engineering standpoint you can make that claim. High quality foam materials are utlized in a lot of applications.

 

For front bump stops you can get the Evo mount cans. They are pricey for what they are but they do not require welding. You will have to weld a bump can in for the rears, the Teraflex rear bolt on bumps seem to be useless, I believe their prerunner kits now come with a weld in rear.
Im setting my jeep up very similar Teraflex 2.5 with arms and Bilstein 5160s but havnt done the bumpstops yet. The jeep performs good now through washboard and rough desert up to 50-60mph just hits hard with regular bumpstops.
The Bilstein 5160s perform great at speed and have a shorter body then similar Fox or Kings allowing you to get more uptravel.

 

Just because I have personal experience with this environment and our Game Changer suspension, I thought I would throw this in.

In Ocotillo Wells, going through the washes with whoops, washboards, etc, our Cloak'd JK (stock engine, Game Changer suspension, MC steel body armor) was running upwards of 70mph.

This was early in 2012 at Tierra Del Sol Desert Safari and one of the first times I had personally pushed our new suspension in that environment. One of our friends in a Hemi'd JK and I decided to race the washes. I won't mention the suspension he had, but we took off, and I watched the speedometer as it climbed from 45-55-65... and the ride was incredibly smooth. I was personally shocked by what our bolt-on high-misalignment rock-crawling suspension was capable of in a pre-runner environment.

Oh... and the Hemi'd JK... couldn't go more then 35 in the same stretch. The suspension just couldn't handle it.

There are lots of great companies mentioned on this thread, but the Metalcloak 3.5" Game-Changer Suspension, as a bolt-on kit with total install time of about 6 hours, truly has set some new standards on what a bolt-on, short arm kit, can do.

 

Thanks for that input! I haven't researched metal cloak at all but this prompts me to give them a serious look!

 

I run the teraflex 3 inch full flex with Elka shocks.... to say it rides nice rock crawling and high speed is an understatement. I'm still fine tuning things, and have been researching bumpstops. Joe, please drop the price on the speed bumps PLEASE!!!!!!!

 

I pulled a couple graphs to compare the compression rates of the speed bumps and air bumps.
This is the Teraflex one pulled from the video above

And this is one I found from a quick google search of a 4" procomp air bump

Link here
http://4wheelonline.com/ProCompAirBumpStop.87707.229887

They seem very similar to me even though they are comparing a 3" speedbump and 4" airbump

 

Another thing to consider with bump can style bump stops is. Where do you plan to mount them with all the oem mounts in the way? I might be wrong here but I don't recall seeing or reading anyone with bump can style stops with the factory spring shock set up.

Teraflex has that market with there speed bumps. Easy of install and perfect for the jk. They are expensive I totally agree with that. But for some applications like the op mentioned these are ideal. Imo

I'm sold on TF speedbumps too. Now I just got to go sell my right kidney to buy them. Oh well, I hope Santa Claus still exists...

 

This thread also shows how a fox air bump can be mounted in the front.
