Outer Limits 4x4 Board

hi guys , im startin a new rig based on a 40 series chassie ,im lookin at runnin coil overs in the front with a 4 link . a arm rear . but i carnt seem to find anything on coil overs ./prices /length / size on the board or in pirate . any links or contacts available . help please .

dobbins and cheezy make them

http://www.polyperformance.com/ is a good place for coilover pricing etc, also try giving chezzy a call

thanks nam , wount worry about dobbins he's to dear ,didn't think of cheezy .thanks again.

cheezy doesnt open till the 5th though.

Most common lengths are probably 14" and 16". 12" also available and Cheezy was talking of making 18". 16" are approx 40.1" eye to eye extended.

Most popular body dia is 2" - takes 2.5" id spring. Over 16" stroke would need a 3" id spring to prevent buckling. Range of spring rates for 2.5" body dia (3" id spring) is not so good.

As well as Cheezy, try Liam at Big Balls (Swayaway race runners).

Prices are around $1000 to $1200 each.

thanks guys ,very helpfull

i think cheezy said they were about 1000 each but then u have to add on the installation costs

installation cost , will fit them myself .or is this a problem .

The prices on race runners have come down a lot- got to love the current exchange rate.

You say - Dobbins are too expensive.

They are about 1/2 what everyone else is quoting here.

I paid $350 for the ranchos 9012's

Sent them to Glen and he modded them to be coilovers for $400 (This is two years ago)

Had springs made locally for $150.

He presto coil overs for $900 - a pair including SPRINGS.

They were AWSOME. you really noticed the 5 shock rates on the ranchos.

Ranchos are not a coil over , they might work ok on a light rig like a zook, bit they are to small and thin to be used for a big rig, sufection went through like 3 ranchos on the front of his surf when it was running them as coilovers.
They just arnt up to the task, the walls on the tube are way to thin and collapse with the weight of the vechile

I think either Overkill or Wizzard do coil-overs. Swayaways site is: www.swayaway.com

i made a pair for mine using ford loius shocks and sj80 springs.
cost less than $300 pr and heaps strong...

Close dude, close but not quite right. Only one of them had collapsing problems, that was running a poly bush in the mounts and placed too much stress on the shock body under articulation, so it bend like a banana !! I hadn't actually noticed had i , until you *eagleeyes* were crawling around under it drooling everywhere and spotted it !!

Yes i've gona through three shocks running rancho based coilovers, and would think twice before doing it again. But it can be done properly, and dobbins were done properly. The key is to make sure the upper and lower mounts are beef, and have johnny joints, heims or something with a decent degree of misalignment to allow for forward/back/side movement as the suspension cycles.

The other thing that must be done with a rancho is to keep the coil/s away from the shock body. Just running a spacer between the two springs is NOT enough, as when they compress and squish up they will contact the shock body [in MOST cases anyway], this will result in the wall of the shock rubbing through and that's it for a rancho. The crap about being 'double walled' means nothing in this instance.

What needs to be done here, IMO is to get some plastic tube, the same ID as the shock OD and slide it over the shock, then have the spring spacer/guide machined up to match the OD of the plastic sleve. You may have to replace the plastic sleve every six months but it's alot cheaper that a shock !!!

Dobbins had addressed this issue with his so i would have no problem running them, although i wouldn't buy them, i'd buy racerunners/swayaways, something with a bigger diameter rod, and a bigger, heavier walled body. One downside to dobbins versions were they were very heavy, but as i said they were beef so if weight isn't a problem this won't worry you.

I know sam's upper/lower mounts were the $hit, not sure how he went about guarding the walls of the shock body, you'd need to speak to him about that.

HTH, Jeremy

PICS ?!?!

You get what you pay for. There's no comparison between Ranchos and other purpose built coilovers.

thanks guy's for the info.

I think the base race runner coil over is only about $7-800
