Overview:
Hays Twister 3/4 Race performance torque converters are a perfect addition to our line of performance flexplates, clutches, and flywheels. Our 3/4 Race series of torque converters is intended for street/strip combinations, with various stall speed offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. The Twister 3/4 Race torque converter perfectly describes a converter suited for an application just shy of Full Race converter.
Hays Twister 3/4 Race Torque Converters--Good names never go away, and neither should good terms!
Features:
- 3/4 Race series converters are built, tested, and proven to support up to 650 HP.
- State of the art Spray Welding process is used in select areas. Spray Welding provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperature
- Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
- All HAYS converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
- Heavy duty Torrington bearings are used for greater strength and durability
- Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
- Increased horsepower and acceleration due to a weight saving, one application design. Almost all HAYS converters are built for one application to reduce weight compared to a multi-bolt pattern converter.
- 3/4 Race series converters are offered in several different stall speeds for GM, Ford, and Chrysler transmissions
- Industry leading Tech Support Team is available to provide assistance with stall speed selection

Excellent Price & Function!
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
An excellent power screwdriver for assembly work where high torque is not needed. I haven't stripped any screw threads yet. The battery lockout feature is nice especially if it's bumping around in a tool box. It feels good and the switch works good too. The battery indicator LEDs work good too. The adjustable angle on the end works good too. Watching it turn through the clear windows is a neat function too. It works better than the Ryobi screwdriver it replaced. The torque is good without having too much torque for lighter work. It looks nice and feels of really good quality. The battery life appears to be good as well. I would buy it again when needed. Excellent price!

Great tool
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
This thing is exactly what I wanted, now everybody saying that it lacks power or anything else, doesn’t understand Tools in my opinion that’s what an impact drivers for. This thing isn’t meant to lag screws into a piece of wood. But this thing is perfect for anything you would just need a normal screwdriver for like installing door handles or outlets or light fixtures or furniture, etc. I find it has plenty of torque, and it could fit into most areas with the swivel design. And feels like a good tool doesn’t feel cheap. And unlike the other ones that have this weird twist motion to activate it, this one has a Forward and reverse button which I prefer.

Power your way on next job. Just buy it!
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
I have every tool known to man. I have tools to fix other tools. Most of them are rubber coated for safety. But I didn’t have a powered screwdriver. Not sure why. This thing is great, I had a project where I had to take apart a Kirby vacuum and this really sped the process, looking forward to using it on 1 million other projects, versus my impact driver, which I used on most everything. Torque seems great, even loosens tight screws, and I like the 45° bend to hold the screwdriver. Seems to hold a charge very well, and it feels lightweight in hand. Not sure why I didn’t buy one 20 years ago. Good value, as I bought it on sale.

Perfect for small home projects
Size: No Size, Style: 4V Screwdriver_Twist 2.0 2pc Set
Good for anyone who is looking to have a small bit and doesn't really use a manual screwdriver to match or use a heavy duty drill. Good for this. Getting small tasks then but it can also screw into wood. I did test it and it's pretty well working not as fast as your regular drill can. The power is pretty high but no it does lose percentage over time. The grip of it's nice and comfortable and easy to use. Seems like it has a magnetic head to help keep your screws together is about the size of a hand but is arguably still bigger? Haven't even lost any pieces to it. Pretty high durability and good for its size
