Anyone know where I can find info on the stock spring rates on the front coilovers?

 

As far as the stock spring rates go If I remember correctly they are somewhere between 500-550 lb , but they dont seem to be in reality , all I know is they are way to soft . When I first got my 2013 xlt 4x4 I hated the way it handled , like a big ol bus ...... If I were you Id go with at least a 650 lb eibach ... But any aftermarket spring is going to be better than those garbage oem springs ... Love my Fox 2.0 with a 650 lb spring rate but Id like to go even heavier like a 750 lb .... check out the link below

Yeah I haven't been able to find definitive answers on the spring rates. Might have to take some measurements and make an educated guess. I'm not looking for a load rating, I need the actual spring rates in lbs/in.

Personally, I'm going for a softer spring rate with longer travel. I want to make sure the suspension geometry stay tolerable.

 

Old thread, but thought I'd add these links since I was recently looking for spring rates as well. There is also a link to another thread with a picture of the chart posted.

This is the 2009-2014 section and the steel body vs aluminum could make a potential difference in these (I do not know the answer to that).

Also a 5 year old thread....

 

amended my post, couldn't find out how to just delete it.

 

No need to delete it! Could be helpful for others later on. That's what these forums are for. I marked them down for my own info since I get a lot of the newer gens through my shop. Thank you!
