Coil question

What is the stock spring rating in lbs. for a stock 2018 trd off road. 550 or 600 or less or more any help would be appreciated.

 

Is 700 an option? I thought they were 650 or 700.

 

I would like to know because I’m installing a ranch hand bumper and was hoping the spring rate was at least between 600 to 650 stock.

 

I recall when I was looking into changing my suspension research indicating stock coils were either 650 or 700 and the Eibach springs that come with 6112s were slightly softer at 600.



Keith @dirtydeeds, David @Coachbuilder1, any help?

 

Thank you

 

I believe the TRD coils are rated at 600........definitely not 700. SR5 's at 550

 

So if they are 600 what are the coils with the 6112 billys

 

Have no idea. Bilstein doesn't state their coil rating. I've run with 700's on my OME's and 700's now on my Fat Bobs.

 

Black Wolf I have one size bigger than stock tire which is 275/70/18 I guess what I’m asking is with the added weight up front should I change the coils and shocks or in your opinion are the stock coils strong enough to handle a ranch hand full bumper?

 

I believe that all Tundra coils are rated at 600 lbs.

 

I went to 700s when I added a RH grille guard and winch on my 07. I recommend going to the 700s with that full RH bumper.
