TRD pro suspension with bumper

Dude I literally stated TRD Pro coil springs are 600lbs which is why I went with 700lb King coils. That thread is from Toytec that’s THEM making a 700lb coil You’re not going to get a OEM out the Toyota factory coil on a Trd pro that’s 700lb and all other trim levels below the Pro are sure as hell not 700lbs lol

 

I think you misread the toytec post. They said they tested a 2016 Toyota coil spring at ~700 lb/in. I’m not sure why you are in a big huff. I was just trying to share knowledge. There isn’t much online about stock coil spring specs.

“We did send the springs from our 2016 out to one of our spring manufacturers to be tested for spring rate. We are doing this in hopes of developing a spring that will work well on the factory shocks and “give a 2 inch lift. Similar to the 112-620 coils or the 521-600's we have. For those interested, i have posted the spec sheet. Spring rate on the factory coil did indeed come back at 717lbs/inch. Spec sheet is attached to this post”

Unfortunately, I’ve never found the mentioned spec sheet.

 

I probably did misread the article. I wouldn’t be surprised. And not in a big huff lol. But reading my previous reply I can see why you would think that. Anyway it’s all good brother

 

The UCA’s on the 22’+ pros are much larger than the previous. From my research they will make contact with the coil at full droop and contact with a 285 tire at full lock with westcott kit installed. But other than that the kit will function as normal on 22’+s

As for the spring rating on the pros I haven’t been able to find a concrete answer some say 600 some say 650 some even say 700+ I think im just going to have to try it and see, if there’s significant sag or performance loss than I can look at upgrading springs

 

I've already quote linked the best possible answer you're going to get about Pro spring rate. The people at Eibach took off OEM springs and tested them in the process of designing their lift springs. The OEM Pro spring rate is 616 lb/in.
