SunCoast Allison 1000 torque converters come in many varieties, from heavy hauling, sled pulling, drag racing, to daily driving. SunCoast designs and manufactures their torque converters in-house. Because of this, SunCoast can supply most any request in regards to stall or torque multiplication. All SunCoast triple disc converters are outfitted with a heavy Duty forged billet steel cover and give an unbeatable lock up performance. The company's race series converter should be used in racing/pulling applications that require a higher "stall" RPM than a standard converter. Increased stall is usually needed in applications where a larger turbo or turbos have been installed and more RPM is required to get the turbo on boost while on the brakes (brake boosting).

These HD converters feature a billet stator and will resist damage to the stator section from excessive brake stalling (over 5 seconds).

Our 1057-3D converter established a benchmark for performance torque converters. Often referred to as theMcRat, it has set numerous records at the strip since it's inception in 2005. Our #57 series incorporates a modified OEM stator and is coupled with the "Velocity Series" impeller. It allows good turbo spool-up with stock size turbos running mild tunes and also offers more efficient fluid coupling than our #56 converter. If you're running the larger turbos and the wild tunes and need to spool, see our #55, #58 or #59 series 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 numbers.
