torque converter for the 1989-1993 A518 non-lockup Dodge 4-Spd
is manufactured and assembled here at SunCoast. Starting with
a solid chunk of steel, the cover is machined to exact specifications
and ends up being nearly double the thickness of the weak factory
cover. Instead of the factory style plastic stator cap/thrust
spacer, SunCoast utilizes a metal Torrington roller style bearing
which is better suited to take the heat and abuse you can throw
at it. The turbine assembly is TIG reinforced and heat-treated,
exponentially increasing it’s lifespan under harsh conditions.
Stall on this model would be described as “close to factory”
at approximately 2200rpm, yet much more efficient at energy
transfer than the factory offering.
year model trucks did not have a lock-up converter clutch
available, so the higher rpm efficiency is critical to pulling
power and heat control. Sun Coast has carefully balanced torque
multiplication and fluid efficiency to offer the best performance
for your truck. Because of the tendency of the OEM cover to
crack, Sun Coast utilizes a steel billet cover for this converter
to assure longevity.
