Overview:

Hays Performance Drivetrain is proud to announce Twister 3/4 Race Performance Torque Converters. These NEW torque converters are a perfect addition to Hays product line of performance flexplates, clutches, and flywheels. The 3/4 Race torque converter is the first series being brought to market and is intended for street/strip combinations, with various RPM 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 name 3/4 Race perfectly describes a torque converter suited for an application just shy of a Full Race version. We do plan to offer Full Race torque converters in the near future. Good names never go away, and neither should good terms! Hays Twister 3/4 Race Torque Converters!

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

Good jacket for the price
Size: Small, Color: Gold, Size: Small, Color: Gold
My son had prom and the theme was, "Your Night to Shine," so he and his girlfriend decided they needed to SHINE. And when this boy picks for a theme, he picks! He is 5'11 150 lbs, very thin, but also muscular and ordered a small. The sleeves were a bit short on him, but that's to no fault of the jacket, it's just been his life as a tall, lanky kid. Great quality, steamed the creases out easily, and stayed together the entire evening. Excellent buy!

Great for the stage. A bit iffy up close.
Size: Medium, Color: Silver-3
Jacket is decent. It’s good for the stage. It looks a bit cheap up close. Probably good for prom but for an adult wearing it to a function I can’t say I would recommend it. But it’s great for the stage! We have worn them many times and they hold up well. I’ve even washed them in the washing machine on delicate cycle without any problems. Just hang it to dry and you’re good to go. It holds it shape and doesn’t wrinkle. A good value for the money. The sequences are this color as they are shown. The sizes are true to fit.

Got this jacket for my nephews Graduation pictures. The fit was perfect and he loved it. The pictures turned out great. If you are looking for a sharp look, this jacket is it.

Disappointed
Size: Medium, Color: Blue
This item runs very very small for men! I have tried this jacket in 2 different sizes for my 14 year old grandson and they don’t fit.
