Daily Driver, Tow Converter and Race Converter 2000 stall
This is our journeyman converter that
incorporates an OEM style stator and custom modified impeller to allow
low end torque multiplication (" gets the load moving") and high end
efficiency ("puts the power to the road"). Combined with the Sun Coast
triple clutch and billet cover it is a great converter for daily
driving, towing and or racing. This converter spools good with stock to
medium size turbos. Larger turbos may need our #55 or #58 converters.
With the addition of the 1055, 1058 and 1059 to our Allison torque
converter line we can accommodate any request in regard to stall, torque
multiplication, efficiency, or other custom application. The stall test
and RPM drops were tested with Stage V transmission, stock turbo with a
350HP tune, stock size tires in our 3500 dually. The example stalls and
RPM drops are strictly to help you decide which may be best for your
truck. Big tires without gear swaps will raise your brake stall test

I was very disapointed in this converter!!!! I have 2005 lly duramax and put the G-max 5 overhaul kit in the transmission and the 1056 3d converter. I put a 100 miles on the converter and it started slipping while the t/c was engaged. I personally called suncoast myself several times. and they wanted me to send back the converter to rebuild it, less than 30 days old and I couldn't get a new converter to do even exchange. Too much money to spend on t/c and not even get a new one. I should have bought M/L converter.
P.S. This has nothing to do with XDP's customer service they where great dealing whith.
