I am converting the rear Air to coil I know I need to install perch "PUCK shape "in the bottom to hold the coil in place and use upper cone "isolator" but I am not sure if I need another perch under the cone on top .I do not want to take the suspension a part and realize I need to order them .thank you
Hey there! Not exactly sure which parts you have or don't have to give you best answer. But if you could take a picture of the parts you have or list items bought I can show you wat you need to do
I'm a little confuse when you said "another perch under the cone on top". On the bottom, it should be puck bolted face down. Then the rubber ring goes on the puck to hold the spring. On the top, there's a cone isolator(optional but highly recommended to further secure the springs).
I thought about doing the same thing but didn't want to take the chance so I don't have a definitive answer but you'll be cutting it REAL close. Even with a 265/70/17 and stock wheels, the sidewall was already extremely close to the UCA, however no rubbing on full lock. But with 285's I feel like you'll either hit the UCA or run the lower on full lock or BOTH. Spacers could be a cheap fix. Hope that helps!
The original tires are 265/65R17 which convert to a 30.6" x 10.4" tire.
265/70R17s are 31.6" by 10.4" tires. Essentially, one inch taller so the chances of rubbing are small.
285/70R17s are 32.7" by 11.2" tires. These tires are 2" taller than the original tires and .8" wider, so you are pretty much guaranteed that you will rub with the stock OEM rims.

I am not sure but as I recall Some where I saw that Lexus GX 470 comes with longer coil in driver rear so is that mean if I would like to up grade the suspension with after market parts I need to lift the driver side coil more .is that true?
I have the MT coil conversion kit, but I thought it’s just to be able to mount the springs in lieu of the air bags. The kit doesn’t address any coil length differences.
I read the description of the MT LT dual rate springs and they are the same length. They are specific L and R springs because there’s a 3% spring compression difference. MT designed it this way for North American left hand drive 120 Prados to compensate for a driver side lean.
I haven’t seen the driver side lean myself, but thats what I understand.
I have run MT springs. They are the same height. The spring rate is different as you have said. I have run the heavy and medium LT springs, as well as Icon Overland, Iron Man heavies, and now Dobinson heavy LT springs. DS lean is a real thing. SSO even has spacers in their coil conversion to account for the lean or for more lift.
