The Keisler RallyeSport 5-Speed PerfectFit® System is the easiest and most complete way to put a modern 5-speed manual overdrive transmission in your 1964.5-1973 Mustang.

Based on the advanced Borg Warner T-45 5-speed built from 1996-2001, the remanufactured Keisler RS® revolutionizes this transmission design, incorporating the robust BW T-56 carbon fiber synchronizers to all gears including reverse. Plus, new SAE 9310 chrome-nickel-moly steel alloy gears (when required), CNC ground in the USA provide high torque, silent operation.

Carbon fiber lined synchronizers provide 7000 RPM silky smooth, low effort shifts, and reverse is also synchronized. Single rail architecture with Guide Plate means you won’t miss a shift, especially the 2-3 at the track. OEM proven high mesh gear design provides nearly silent operation. Enjoy the new best-in-class 5-speed Keisler RS® at a price that beats the competition every time. One drive with the Keisler RS® and you won’t want anything less.

Complete auto-to-manual kits also available, including bellhousing, flywheel, clutch, pedals, etc. Call for details!

Rick Liwush - '67 Mustang

rick_liwush_with_andy Hey guys, just wanted to share with you some pictures of our 1967 Ford Mustang.

It is a true S code. With the help of your staff we were able to come up with the correct application for our project. We have installed your TKO 600 RR. This transmission works far above our expectations. Installation was a breeze. A few hours and were ready to roll.

The TKO 600 RR is married with a 428 CJ that is supercharged with a Pro-charger F1R.

At the present time we are pushing 781 hp with 813 ft/# of torque.

Andy and I would like to share with all those who are on the fence post on buying your products, “ There is no reason to hesitate in your purchase, this company really puts out a wonderful product that is backed up with a very knowledgeable Tech department.”

Your staff and tech personnel were fantastic. Your Tech department was informative and patient with help to any questions that may have risen. We have be sharing our story with all those we come in contact with at many national and regional events.

Thanks for a great Product and especially your service.

Keep the pedal down…

Rick & Andy

Dr. Tom Thurman - '67 Mustang

Keisler,
I appreciate the fact you stood behind your product with service. The picture is my son with the Eleanor with your Keisler five-speed behind this 428 COBRA jet. Numerous people ask me what kind of transmission was behind this 428. About 50% of the people knew what the Keisler five-speed is, I am doing my best to put a good word in for your company. The shifting is phenomenally smooth and I would highly recommend it with the hydraulic clutch especially.

With Respect and Integrity, I Remain, Dr. T. Thurman
