Get the Torque to the Rear Wheels with a Bowler Performance Transmission

Bowler Performance Transmissions has been in the transmission business since 1963. When you’re in business that long, you learn a few things about making a transmission that works and doesn’t break. That’s why car builders like the Ring Brothers, Johnson’s Hot Rod Shop, and Rad Rods by Troy trust Bowler to build transmissions for their projects.

Summit Racing carries Bowler Performance automatic transmissions, manual transmissions, and installation components including these:

Tru-Street Automatic Transmissions
Bowler Performance Tru-Street Transmissions are not rebuilder’s specials. Each is fully remanufactured with new steels and bands, seals, gaskets, bearings, and other components. One technician handles a transmission build from teardown through assembly and testing on the in-house dyno. Bowler Performance even includes a matching torque converter.

Tru-Street Transmissions are covered by a 24-month limited warranty and don’t have a core charge, which is nice.

Carbon Edition Tremec TKX and T-56 Magnum Manual Transmissions for GM
Bowler Performance Carbon Edition TKX and T-56 Magnum manual transmissions are about as close to the perfect stick gearbox as we’ve seen. The transmission are hand-built and blueprinted to handle big torque and high RPM shift points in extreme use environments like road course and autocross competition.

Carbon Edition transmissions have an REM Isotropic finish on all gears, main shaft, counter shaft, and shift rails. The process reduces friction, noise, vibration, and torque loss. That means extended component life and better shift feel. The transmissions also have custom aerospace polymer fork pads that can withstand more heat and friction for more consistent and crisp shifts.

The Carbon Fiber Edition TKX five-speed transmission is rated at 600 lbs.-ft. of torque capacity. They can handle engine speeds of 8,000 RPM and shift points up to 7,500 RPM.

The Carbon Fiber Edition T-56 Magnum six-speeds are rated at 700 lbs.-ft. of torque. They also have carbon/hybrid synchro rings in all gears, an updated second gear and 1-2 gear synchronizer hub, and a NightStick billet shifter.

Tru-Shift Throttle Correction Systems for GM 700-R4 and 200-4R Transmissions
If you don’t get the TV cable for your 700-R4 or 200-4R transmission set just right, you’re going to have a trans that won’t shift right—and one that won’t live a very long life, either. A Bowler Tru-Shift Throttle Correction System is the easy way to set the cable. Simply bolt on the supplied bracket and carburetor cam assembly, install the TV cable, then run the accelerator to wide open throttle. The cable will automatically adjust itself with no muss or fuss. You won’t have to remove the carburetor or throttle body, adjust cams, or check line pressure.

Summit Racing has Bowler Tru-Shift Throttle Correction Systems for Holley 4150-style and Edelbrock four-barrel carburetors as well as Holley Sniper and Sniper 2, FiTech, and MSD Atomic throttle body EFI systems.

Summit Racing carries other Bowler Performance products including hydraulic clutch master cylinders for GM A-body and Camaro/Firebird; lockup control modules for GM 700-R4 and 200-4R transmissions; mechanical speedometer adapters; and transmission crossmembers.
