Bowler - 1999+ 4L60E/4L65E/4L70E Lock-Up HD HP 1800-2000 Stall Converter

Fits: 1999+ 4L60E, 4L65E, 4L70E (lock-up)
Best for: Small blocks and mild big blocks up to 400 HP

The modern-transmission counterpart to Bowler's 700-R4 stall converter — same mild street stall, same drivability, built for the 4L60E family. A slight stall wakes up acceleration without turning your daily driver into something you have to fight at idle.

What's inside:

• Furnace-brazed fins
• Torrington bearings
• Modified stator for improved low-speed response
• Premium lock-up piston and clutch lining
• Pressure-tested and fluid-balanced, every unit
• 90-day warranty
