Advanced Features Explained

The billet lock-up design is a key feature that sets this torque converter apart. Unlike traditional converters that use stamped steel, billet construction means the parts are machined from solid metal blocks. This results in a stronger, more precise component that can handle higher stress without warping or failing. The lock-up clutch inside the converter engages at cruising speeds to create a direct connection between the engine and transmission. This reduces energy loss caused by slippage, which not only improves fuel economy but also lowers operating temperatures, extending the life of your transmission.

The 3200 stall speed is carefully chosen to match the power characteristics of LS engines. Stall speed refers to the RPM at which the converter allows the engine to spin before fully engaging the transmission. A higher stall speed lets the engine reach its power band before the vehicle starts moving, which is especially beneficial for drag racing or aggressive street driving. However, this converter balances that with smooth engagement, so you won’t experience harsh or jerky starts during normal driving.
