I'm looking into possibly getting the 2.5 inch lift coils from 4x4parts.com. Does anyone know if they actually provide 2.5 inches of lift? The web site states that "Amount of front lift will be limited depending on which coil over shock you are using." I plan on upgrading the front shocks to something like Rancho or Bilstein heavy-duty shocks. I don't want to spend an arm and a leg on shocks at this point.

Are these lift coils compatible with the Bilstein adjustable shocks? If the coils don't actually lift the front 2.5 inches, I may go that route just to bring the front end up a true 2.5 inches. Unless anyone has a better idea. :)

I had them. They do give you 2.5 of lift. They were really stiff at the being but softening up a little after 1000 miles.

the 4x4 parts springs are stiff for the added wight of a bumper skids and sliders they can go on the OEM shocks but work better on an aftermarket shock. You need a spring compressor to install them. For the lift they give they are a decent value. They also now have a slightly softer coil better for the guys closer to stock with out the added weight of bumpers and armor.

dont do it HUGE mistake,I had them and I think everyone that had them has replaced them with something else.I believe I still have a new 1 in my garage that I had sent to me after they both rusted after less then 1 year.I know most never had a problem with them but here mine when removed

I think I'm going to plan on going that route then, and upgrading my stock shocks too. Unfortunately, I can't do it right away since I promised I wouldn't spend any more money on the truck until after we buy a new house (currently waiting on an offer we made on a short sale). But at least I know what to look forward to now, lol.

I've already seen your pic on here a few times, Jeff....I've been browsing these forums for a while. It seems you're the only person who has had that much trouble with this product. I'll spend my $140 on these coils, and if they rust, you can say "I told you so." :)

I'm not interested in doing Radflos or Icon coilovers or similar due to the maintenance required and the initial cost. It's just not in the budget right now, and I'd rather upgrade my suspension sooner rather than later, since I do wheel my truck a bit, and I want to do the lift/shocks before I break something.

Also definitely don't want to do spacers as I want a functional lift, not just a good-looking truck. The adjustable Bilsteins seem neat, but they aren't going to give me as much lift as I want.

there is no CB contact with the springs as its not a spacer. spacers give the issue as they make the OEM strut coil longer the coils give lift by being slightly longer then the OEM but they are also stuffer giving lift 2 ways.

So these coils are ok to use with the stock shocks?
That is the impression that I'm under. But I think that if you do much wheeling, you want to upgrade your stock shocks anyway. I'll be upgrading mine. A friend of mine just broke a shock last weekend....

I may buy next week
Cool, then *you* can tell *me* how they work out for you. ;)

What are you doing about lifting the rear, Hunter?

I already have 3inch spacers and 2inch blocks. I will be installing my Titan swap in the next week or so (as soon as my buddy fixes his lift). That, after some reading, will decrease front height since the shock will be lower down on the lca. So to get back what I lost after Titan swapping I will use lift coils.

My other option was finding Titan coilovers but have come up empty handed.

I will eventually buy sway a ways but. It's not in the budget right now.

It will all come down to what my stance is post Titan swap

That's not actually true. Coil bucket contact is a result in the geometry between the upper a-arm and the coil bucket. Lift, any lift, changes the relation between these two components.

What you are doing with a lift (any lift) is reducing the amount of potential extension, while increasing the amount of potential compression. At a given amount of extension, you WILL have CB contact, no matter how it is lifted.

The limiting factor on these trucks for extension is the CB and the limiting factor for compression is the bump stop or the shock travel.

If a 2" spacer lift has a given amount of propensity toward CB contact, then a 2" suspension lift will have the same propensity.

No you are incorrect. Only spacer lifts cause coil bucket contact.
An easy way to see if a lift will cause contact is to jack up the front so the tires are not on the ground to see if the upper control arms are sitting on the coil bucket.

Here is pictures of when my wifes truck then it was stock. As you can see the tires are not on the ground and the control arm does not make contact with the coil bucket.





Now here are some current pictures of my wifes truck with a 2" PRG pacers.
As you the control arm is sitting on the coil bucket at full drop.





Now here is my old lift. Just 2.5" AC coils. As you see with the tires are off the ground and the control arm does not sit on the coil bucket.





The same as with my current lift. A set of ICON coilovers set up for stock control arms. There is no contact.

Ah, the same old argument revisited. I would like to see a 2wd front suspension, without the coilovers installed, cycled through its full travel...pics taken of course. Then I would like to see a 4wd front suspension, without the coilovers installed, through its full travel...pics again. Just a quick experiment to show everyone when the contact occurs with how much down travel...

I am 2wd, running radflos...I had contact. Decided to throw on cst spindles...contact remained, which I expected.

How much lift are your ICONs providing? Perhaps it is just enough to prevent your CVs from self destructing (under 3 inches of lift)......and how large of a spacer would be needed to replicate that amount of lift for a stock coilover...just a thought I would like to throw into the fire. As you stated, they are set up to run with the stock UCA...what about cranking them up higher and testing for contact? You could also volunteer for the experiment of taking pics of the full range of travel without the coilover installed????

Pearls before swine.

There is nothing intrisic about a new longer coil that prevents coil bucket contact as opposed to a spacer. You are doing the same thing to the truck. And that is moving the suspension arms to a lower (more extended) position. If you move these enought, you will have contact, unless the downward motion is restricted by something.

Elimating coil bucket contact comes from restricting droop. In the above pic, the droop is likely restricted by the shock itself. Tell me what is restricting the droop in the pic. Is it the shock or is it something else?

If you look at desert racing trucks, they have limiting straps to prevent the shocks from being the limiter of extension because this tends to tear shocks up.

Other types of vehicle use bump stops to prevent metal to metal contact. These are the stops included with some spacer kits. Is there a bump stop preventing contact? If so that is not unique to a coil lift as opposed to a spacer lift.


ETA: On that coil lift, were you running stock shocks? If you run longer spring on stock shocks you will not have coil bucket contact because the stock shocks will limit extension. However, you may end up using the shock as your bumpstop in compression. If you run a longer coil and a shock that allows full travel, you will have contact.

Intrinsically, I feel good that I have $700 limiters. Esoterically, I feel good that I have $700 limiters. Financially, I'd like to have the best suspension for the money. Throw your swine now. Otherwise, sink with the pearls.
