03 4x4 double cab Fabtech coilover replacements

So I picked up an 03 TRD 4x4 double cab, supercharged with a 6" (I believe) fabtech lift. Long story short the suspension feels horrible and kind of shaky. I noticed a rhythmic....bounce i guess, at speeds over 50mph. Jacked the truck up and got some play from side to side in the tire, up and down had no play. so I replaced the outer tie rods (inners had no in/out play so i left them). The steering feels fine on paved roads but on a fire service road with decent washboard its unmanageable. There is decent play in the steering shaft so I am going to weld that in the next day or two but I think the coilovers are original from the lift install several years ago. This will be my new daily as well as my camping rig so I need to make sure its 100% before I switch from my current 02 dcsb.
So heres the question. I have read that I can use the RCD bilstein 5100s and eiback 620 coils to replace the current ones but I am having a hard time confirming that this will work with the first gen tacoma and fabtech lift combo. I apologize for asking a question with so much info available during a search. The answers are just diluted and hard to be 100% that I am going to order the right stuff. Any help is appreciated, thanks in advance.

 

I thought the Fabtech lift included giant spacers to space down normal height/travel coil spring/shock.
Maybe you can find the specs of the Fabtech shocks and compare the extended length and minimum length to Bilstein specs.

 

Theres no spacer, I have seen that as well. This looks to be extended coilovers. I see some markings I'll take pics of, no brand names visible though.

 

Part number on the shock says FT70001 then under that it has smaller numbers that read 005432 0505

 

Thanks! They are 17" Pro Comp Xtremes with BFG K02s 305/65s

 

King and Radflo make replacement coil overs for the 6 inch Fab Tech lift. I can't find anything about Bilstein having one. That doesn't mean they don't but I can't find one. The King's and Radflo's are running anywhere from $1,200 to $1,500 for the set. I would call Bilstein and ask them about it. They would probably be a cheaper route. I see what you mean about all of the info but no definite answer. You could always go back with the Fab Tech coil overs if all else fails.

 

After a quick search these are the fabtech front struts for the 6" lift I have on the truck right now. They are pretty cheap to order new ones, about $140 a piece. The price difference is pretty severe. I am going to try to call Bilstein tomorrow to ask about the 5100s. I have seen the Kings but not the Radflo, Ill check those out right now. With how crazy the cost difference is I am wondering if I will see a better ride with the King or Radflo vs. the Fabtech replacement ones?

 

Yeah, that is a huge difference in price. I'm sure the King's and Radflo's would offer a better ride and performance, but is it worth that much difference in price? I would go with the Bilstein's if you can find some that works. But I am cheap!

 

I'll hit them up tomorrow and see. I'll have to do some more research and figure it out. Probably need to check my body mounts too. I'll post back what Bilstein says. Thanks for the input, I appreciate it.

 

You are very welcome. Yes please post what Bilstein says because I would like to know if they would work.

 

Probably a little too pricey for what you want, but these will also fit:

Those are really nice but just a little spendy for me. I dont want bottom of the barrel but I'd like to be somewhere in the middle.

 

Just spoke with a Bilstein rep in California. He said they do not offer a direct replacement for a first gen tacoma with a 6 inch lift. His suggestion was to measure compressed and extended lengths and call back to try and match it to something.

 

Well that sucks. I guess it's time to break out the measuring tape.

 

that or cough up the cash for kings.....leaning towards that direction the more I look around.

 

Just came across some info that might end up really useful. I need to read some more but it looks like first gen tacomas, first gen tundras and 3rd gen runners have interchangeable coilovers. I believe the top hat may either have to be turned 180 degrees or an adapter plate used. I'm going to keep reading but if that's the case, Bilstein does make RCD 5100s for a 6" lifted first gen tundra.

 

You may be on to something.
