Gee, that might bve a good theory if the Dakota R/T actually called for
high-octane gas. The R/T calls for 87 Octane, check the Owner's Manual.
The 5.9 in the Dakota is the SAME engine that has been used in other 5.9
applications. The same as the 5.9 in the Ram, the same as the 5.9 in the
B-Van, the same as in the 5.9 Grand Cherokee Unlimited. The only way you
get 250HP versus the normal 245 in all other 5.9 engines is one reason:
unique exhaust.
The R/T Dakota is lowered compared to regular Dakotas 1" overall. This
combined with the larger than normal diameter rearend housing makes the
travel from the frame bump-stop to the axle tube a 1.5" difference. THAT is
the problem.
The information I got on the rear suspension travel being the culprit came
from a very trusted source at DaimlerChrysler.
Of course we can speculate all we want, and yes, I will admit that I could
be way off base, because DC will *never* let slip exactly what the problem
was/is.
