First off, let me say that if your going to get a set of coilovers, save yourself some hassle and try not to get anything bigger than a 2.0. This will limit you to a max of 16" of travel but the number of suppliers is quite large.

For those of you that want to run a 2.5" body, King Shocks is your best source for springs up to 16".

I blindly got the 18" travel 2.5's and from this point on it's a whole differant world. There are only 2 companies I could find that make 18" coils. Hypercoil will make you a set for $320 a piece and prefers not to go below 700lbs. Luckily, Eibach has just released production units this week. Cost is $100 each and rates are 400 to 800lbs. I am still waiting for their main distributor to get some in but it should be soon.

3.0? Didn't ask and wouldn't want to know.

Now for my rant. :mad3: The people who answer the phones at Avalanche Engineering don't know jack shit. They did ok on my shock order so after I determined what I needed I ordered the springs from them too. Well they sent me 16" lower coils and when I called them and told them that they were too short and were allowing the isolator to drop off the shock body they said that was ok. I told them it wasn't ok and to get me the right coils. Two days later they are telling me that they can't find 18" long coils. They will sell you the shocks but have no idea where to get coils for them. Well I gave them the pirate salute :flipoff2: and UPS is supposed to come pick up the useless coils.

Here is a pic of what their phone operators think is ok for a coilover shock to do at full droop.

Yep I got the same kind of problems from them. Clifton was pretty nice and finally set me up with the right coil rates but the guy who took the order and was supposedly the "coilover salesman" had no idea. One solution is to buy tender coils. They are extremely light coils that just sit at the top fully compressed and keep tension on the coils when you get droop, but they are pricey. Someone was telling me about a certain kind of limit strap you can use that bolts in with the coilovers and keeps teh coils in line at full droop but I haven't seen these anywhere. If you figure anything out let me know.

Yeah that is a common problem with using 18" travel coil-overs. In the past those shocks were mainly used for off-road racing where they use higher rate springs, it might take a while for the coil spring suppliers to catch up and make longer, lighter rate coils. Another option you have is to make an new slider that goes between the coils. You can make one like the SAW 2.0 slider, It has a muck taller shoulder on one end which allows it so stay on the shock body in your situation. That is why Avalanche "engineering" doesn't know WTF is going on because they mostly use 2" shocks and the can run short coils like in your case and get away with it. Actually you can buy a Fox 2.5" slider and it should work just fine. If you need custom springs, try Coil Spring specialties, 758-437-2025, talk to Dave, they specialize in making custom coils and make many for King.

Hyper coils are a little pricey but well worth it. Im running 2.5"x18" on the front of my dodge with spring rates of 400/325. I went with Hypercoils after some bad experiences with Eibach's settling as much as 2":eek: and thier customer service was terrible. The hypercoils have held up great to a lot of full flexing and HARD landings.

Bill at Mirage Racing in Lancaster is a great source to get them from. He builds up and does race prep on Pro Trucks, and is very good and help you figure out spring rates. Plus, if you dont screw up the springs, he will let you swap them for different rates.

EDIT: Oh yeah, the number for Mirage is 619-562-5533. Bill Varnes is da man!

Thanks GOAT1 for the info on the Fox slider. I will be ordering a pair for the extra measure of security.

Ramstien, I'm gonna take the chance with the Eibachs, the hypercoils are just too expensive for me right now. Not sure where the coils that you got were made, but the 2.5 coils are being made at their Germany plant. This is the same place that made the Frog's coils.

Parker Pumper now has the Eibach 18" long 3"ID coils in stock. 400lb rating only currently. Price is $97.50 each. They are still waiting on the helper coils. They were sent the wrong size. Hopefully now my project will get back on track.
