Well maybe I can give a perspective on it. I installed a set of
DJM 1" coils on my ride with a 4.3. DJM doesn't have a spring
for a 4 cyl or 6cyl. They sell a coil based on either a x-cab or
a standard cab, or whether the ride is a 2wd or 4x, I believe.
So after I installed the coils it took about 6 to 9 months for them
to fully settle and they went from 1" to 1.5/1.75". And thats with
a 6cyl. With the extra weight of the v-8, you could expect a set
of 2" coils to settle either at 2.5 or more likely 2.75 possibly even
closer to 3", but I doubt it. I also think the brand coil you get
is a important as well. Have you ck'ed out JTR's site for
what he has to offer in the way of coils, and if not any to offer
at least ask what they would recommend as far as coils ?
