Here is the response I got from ARB when I inquired about OME springs for my
CJ5 . It answered a lot of my questions. My plans for this summer is springs and rear disk brakes
Hi Terry-
Funny you should ask. One of our employees that works in purchasing just
did this conversion on his 81
CJ7 . He used CS014F springs on the front but
his is the Iron Duke 4 cylinder. With your V8 I would recommend either
CS036R or CS037R springs at all 4 corners. The spring rate is the same, but
there is a 20mm difference in arch. The CS037R's are the lower height
springs of the two at 185mm primary free camber. The CS036R's are 205mm.
Both have a spring rate of 188lbs per square inch. I have attached a picture
of the
CJ7 so you can have an idea of the height with CS036R springs in the
rear with close to the same set up as yours. The tires are 30x9.50-15. Hope
that helps.
*Keep in mind the OME springs were designed for the YJ Wrangler and we do
not offer a "CJ kit". Any kits you see on the market are kits that have been
put together by a retailer using our springs as the basis. Some use our
bushings, others use all kinds of different pieces to make the conversion
from late CJ springs to YJ springs. We can't offer much support on the
"kits" as we are not the ones who put them together.
Best Regards,
ARB Technical Support Team
