Factory front coil Spring rating of a 2018 trd off-road

Can anyone tell me what the factory coilovers of a tundra are rated at? The truck is a 2018 with the trd off-road package if that matters I don’t think it does but just putting it out just in case. Thanks to all that answer in advance.

 

Are these coil overs 550lb to 650lbs?

 

Ive seen 550lb thrown out there. Who knows what model that is though. There are 2wd and 4wd spring rates

 

I have a four wheel drive I was hoping on the 4x4 and off-road package that the springs were at least 600.

 

I’m not sure if the off-road “TRD” gets different springs than the non-TRD. I know the shocks are different, but hadn’t heard that the coils were as well.

I believe that most of the high end coilovers use 650-700# springs. I know my ADS are 700# for CrewMax. Would be 650# if it were a lighter truck with smaller cab.

 

It’s about 550 when new. TRD Pro is about 625.

In practical terms, if you are running a winch and steel bumper an upgrade is likely in your future.

 

2021 sr5 4x4 crewmax is 550. The eibach coilovers I got are 650. Works perfectly with my ironman front bumper and synthetic winch.
