Yes, the LS Engine Series are some of our most popular builds. The LS engine family was designed by GM to be the only V8 Engine used in their real-wheel drive cars and trucks. These engine types from the LS1, LS2, LS3 and LS7 are hugely popular in performance vehicles due to the compact design compared to the displacement and power output. Sling Shot has done a lot of R&D in this engine family with great results.

3. Which vehicles need Torque Converters?

All vehicles with Automatic Transmissions require a Torque Converter. The Converter takes the place of the mechanical clutch, to give the vehicle drive and momentum. Many automatic transmission problems can be as a result of a damaged torque converter. Most modified engines will require a high stall torque converter.

4. What are the Most Common Torque Converter Problems?

Most problems with torque converters actually arise from incorrect set up or poor rebuilds. Especially in performance engines, increasing the power output of your engine will mean that you will need to increase the strength and durability of your High Performance Torque Converter.

5. What is a Lock Up Converter and Do I need one?

A Lock Up Torque Converter, also known as Torque Converter Lock or Torque Converter Clutch, refers to the use of a lock up clutch within the torque converter that eliminates slippage for economy.
Most modern converters are now built with a lock up clutch as standard to allow drivability on the roads, whilst still maintaining the power when it matters. Whether you need a lock up clutch in your rebuild or custom converter will depend on the engine type and application.

6. Do you offer a Repair Service for broken Torque Converters?

Yes. Many Torque Converters that come to us can be repaired and rebuilt, and in many cases it is cheaper to do so. If you do require a completely new Torque Converter is it still a good idea to send us in your old converter to aid with R&D with your new build.

7. What is a Stall Converter?

The term stall converter usually refers to a High Performance Torque Converter where the stall is specifically altered to suit high performance engines.

8. How do I determine the Stall Speed of my current Torque Converter?

A Torque Converters’ stall speed is actually the speed that the converter holds the engine at without going further – ie where it stalls. The best way to determine stall when assessing your converter is to use the foot and hand brake.

9. What causes Torque Converter Shudder?

Torque Converter Shudder is caused by the lockup not applying properly when in use. This could be as a result of an ECU or valve body problem or potentially a burnt lockup lining.
