bilstien B12 springs
hey guys, I'm planning to change out the Moog FJ springs I have in the rear to some Bilstien B12 36-281824, since I am going to take out the airbags and replacing the jounce bumper too. I figure I want better fitting springs.
I order the 36-281824 hopefully these are going to give me what the Moog gave me, with the Moogs, i think it was 36+ on the driver side rear and 38ish on the passenger side, also the pass side spring never seated correctly.
plus I have a constant 200 pounds or so from the rear battery and sub setup.
should I order the 36-281817 over the 36-281824 ?
will it be a perfect match to the old springs since I also have constant weight.

springs are installed, waiting for my replacement spring insulator to come so I can take out the airbags with a hole.
measurements 37ish on driver rear and 38 3/4 on the passenger rear.
little bit over half tank of gas, 275/55/r20 tires at 40psi. sub and amp and rear group 31 battery total weight is a little 200 to 210 pounds, original spare 265/65r17 is still under the truck.
so far its about 1 inch higher than the moog 81081 with 40-50k miles?
the bilstein b12 springs measure at about 16 inches. also it fits so much better in the bottom spring perch.
took it out for a drive and it is firmer. the moogs were soft. I can tell the bounce is less. hit the speed bumps and it feels firm and better.
glad I went with the longer springs, I wonder how much it'll settle. might have to adjust my lights a little bit.
