From what I've read Toytec pairs their 600+ lb Eibach springs with Tacoma/4runner 5100 bilsteins and they seem to be a great setup. So my question is, why wouldn't these same bilsteins work well with Tundra coils that have roughly a 600# spring rate?
The Tundra TRD coils are ~595# spring rate. Usually ToyTec packages their COs with 600# coils. The coils used on the ToyTec/Eibach COs are taller than the stock and/or TRD coils. I already thought about this and measured before I went with the Eibach coils.
I'm trying to find out for sure if my tacoma/4runner 5100 bilsteins will work but it seems the Tundra 5100s work well with these.
From what I understand you'll get 2-2.5" lift by switching out stock springs with these Tundras. If you want up to 3" then you'll need a spacer for sure.
Crap, I did forget one other thing...Not sure but you may have to use the Tundras top plate. Can someone confirm that part?
You don't need to use Tundra top plates. I used my stock top plates when I had TRDs.
Warning, Tundra shocks are valved stiffer and will ride harder.
On my 2000 (each year had different factory ride heights so lifts will yield different heights), the TRDs gave me ~2" of lift.
A little back story to my lifts.
Are we ever happy with our lift? doubtful
Do we want more lift? always
My first "lift" was a set of airlift bags in back. They were great but I realized that I wanted to lift the whole vehicle and not just get rid of the tail sag. I returned them after 2 weeks. Stock coils (~150#). I also replaced my shocks with "M" brand shocks, worst decision. Two weeks later I replaced those with a set of HD Bilsteins. Great shocks!
2nd lift. Tundra TRD coils (~595#) in front, OME 890 (190#) in back. Great ride and nice amount of lift.
3rd. Replaced the 890 (190#) with 891 (210#) for a little more lift with added weight.
4th. Added a ToyTec topout spacer in front and 10mm trim packers in back.
5th. swapped out the TRD coils for ToyTec coilover setup. (600#)
6th. I just bought a pair of 9.25 wrap LC coils (160#) for the rear. I'm hoping that they compress to give me ~4.5" then I can bring up my COs if needed. They gave me ~ 4.5" of lift with my normal load.
7th. I will be swapping the 9.25 wrap LCs out for OME 861 (220#) soon. The LCs ride/flex great but compress too much with all of my wheeling/camping/ ExPo gear in it. TBD
**As I have gone along I have replaced shocks to increase travel but only use Bilsteins!**
***If I was to start over I would start with Coilovers in front. Even if I only wanted a couple of inches. This way I could dial in the exact height/rake I wanted for the rear coils of choice. ***
