Dont let the exceptional value fool you into thinking Tork Master Converters are not packed with lots of quality features which make them the best value-priced street performance converters money can buy. These converters perform best when paired with stock to modified engines up to 350hp/350 ft lbs. of torque, and lighter weight applications, like street rods. The Tork Master will provide noticeably quicker launches and harder acceleration while maintaining normal daily driving qualities. Upgrades like a new precision alloy steel pump drive tube, needle thrust bearing when factory equipped, new thrust washer between turbine and cover when required, and pressure tested and fully balanced by expertly trained technicians. Notes: Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. Notes: Not recommended for big block, supercharged, plate-type nitrous oxide or trans-brake applications.

The Holeshot converter is an excellent choice for vehicles with some performance engine modifications, particularly big cams that tend to reduce low-end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Holeshot converters feature furnace brazed impeller fins and turbine, new precision alloy impeller hub and new heavy duty needle bearings. Other features include fully balanced and pressure tested by expert technicians. If your vehicle is equipped with a plate type nitrous system or supercharger, please refer to the Nitrous Holeshot line of converters. Notes: Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. This converter is Not recommended for supercharged, plate-type nitrous oxide or trans-brake applications.

Features:
- Reverse Lockout Meets NHRA And IHRA Requirements
- Carbon Fiber Look Without The Cost
- Reliable And Race Proven Shifter Design
- The Magnum Grip Stealth Pro Ratchet shifter is one of our most popular and easiest to operate race shifters. Features include positive ratcheting design that self-centers the handle after each shift giving you maximum clearance behind the shifter and will not allow you to miss a shift by over-shifting a gear. The reverse lockout feature only requires one-hand to operate and meets both NHRA and IHRA safety regulations for racing. Other features include a neutral safety switch, backup light switch, along with a simulated carbon fiber wrapped aluminum cover. The cover is treated to a high quality hydro-dip process and material to add a high-tech and realistic carbon look to your vehicles interior, but at a substantial cost savings versus carbon fiber. This shifter includes our Magnum Grip shift handle with replaceable side grip plates, tough black anodized finish, 5-foot long Super-duty shift cable, gear indicator, cable brackets and transmission levers for use with most popular 3-speed transmissions.
