Rear Spring Advice

I’m looking at adding some 1”-1.5” lift rear springs on my ‘24 TRD Pro. The front already has the Westcott spacers.

I’m looking at the Eibach, Bilstein and Dobinsons options and I’ve seen posts indicating actual lift heights may vary.
If I go with the 1.5” Bilstein, for example, what actual lift amount should I expect?

We also expect to carry large loads at time so I’m considering a heavier spring. Bilstein has a 1.5” spring rated for add’l 400 lbs. Is 400 lb enough to significantly impact the ride when we don’t have a load on the car?

 

The lift heights vary because most people don't have exactly the same weight on there, plus different models came at different heights from the dealership. The baseline we use is 20" front and 22" rear, but some were 19.5/21.5, 19.0/21, 20/21.5, etc. All over the place.

C59-599 Dobinsons coils tend to sit at 23.5" from hub to fender with no rear weight and no 3rd row seat. 3rd row seats drop it down 1/4" for example.

If you buy springs that are rated for 400lbs, but you don't have 400lbs, you'll get more lift, because you don't have the required weight on them for them to sit at the listed lift height. It would probably sit at least 1" taller with no weight.

 

Is there any issue with adding a 1.5” spring to the rear Fox suspension? Anything else I need to consider?

In researching all of this I recall some people stating a 1” spring is no problem, but going higher could require new shocks?

 

Looking at the Dobinson coils, they are advertised to have a 2” lift. If most tend to sit at 23.5” (1.5” lift), is the 1/2” difference due to loads people are carrying?

Ultimately I think want to get 1.5” of actual lift on the back which will get some forward rake again. To do that I’m not sure if I go with 1.5” springs, or now 2” springs like the Dobinson ones mentioned? Will 1.5” springs result in only 1”-1.25” of lift?

 

Dobinsons have 12 different rear coils for all different lifts and load ratings. C59-599 are not 2" lift coils, not sure where you got that from.

And yes, most stock shocks can't handle more than 1" of lift, or they run out of travel and top out often.

 

I saw the 2” Dobinson’s here. But maybe they are front coils?

Their description is wrong. I've seen them have wrong info on a lot of different pages.

 

i have Eibach T13 coils in the rear at 1.5”. Loaded with vaca stuff and 2-3 people it might drop 1/2”.

this is loaded. Its rides beautiful loaded and unloaded and perfect for my needs
