The larger window allows for higher RPM shifts. Notice how large the window is between the lugs. Stock Muncie input on the left, and one modified with Liberty’s Pro Shift Ring on the right.Ī JT5 Enduro gear has this removable dog ring faceplate. Every other tooth has been machined away to create the 18-tooth gear. The standard A833 slider ring featured 36 teeth, but Chrysler was the only one of the Big Three to offer an 18-tooth slick-shift slider ring. In fact, you could purchase from Chrysler complete, new gearsets and sliders for the A833. You purchased the sliders and modified your own gears. This technique is called “slick shifting.” From the 1960s to the early 1980s, it was possible to find new sliders specifically made for slick shifting. The downside is that the engagement teeth must carry double the load they were originally designed for. At 6,000 rpm I now have the surface speed of a 3,000-rpm shift. So, getting back to those 36 engagement teeth, if I remove every other tooth on the gear and slider, I’ve effectively cut my surface speed in half. However, if I remove every 10 pickets from the fence I can get the stick through the fence at 60 mph just as easily as if I were standing still. If I’m standing still, I can stick it between the pickets, but if I’m driving by at 60 mph, the stick may bounce off the fence. I always associate this with trying to place a stick through a picket fence while driving by that fence at 60 mph. When spinning above 6,000 rpm, the surface speed of the gear and slider can be very different in certain ratios. The matching slider that engages the gear has the same number of teeth. In a typical synchronized 4-speed, such as a Muncie, T10, Chrysler, or Ford Toploader, the transmission has 36 engagement or clutch teeth on the gear. With the newer style of metal alloys available today combined with the state-of-the-art CNC machining and 3D modeling, gear design has evolved to a level that allows for stronger horsepower capacity within a smaller configuration. Endurance events, such as NASCAR-style racing, require designs to be as light and efficient as possible. In a road-race environment, automatic design does not allow for quick ratio changes, quick tear-down, or the availability of efficient 4-, 5-, 6-, or even 7-speeds. Daytona may require a different set of ratios compared to Sebring. There are many gear ratios needed to negotiate various race tracks. You can copy and paste this link to share: This column will only work with steering shafts that have a spline mount and outside securing bolt.SHARE THIS ARTICLE: Please feel free to share this article on Facebook, in Forums, or with any Clubs you participate in. Over the years many cars have had column swaps. This is the shaft that goes from your steering column to the steering gear box. *Please double check your steering column shaft. Please double check your wiring as this column will have an 11 pin harness connector. *Note ~ Some 1976 cars have a 13 pin steering column wiring harness connector. Gently bend back to shape when installing. *Note ~ The firewall mounting plate will be bent slightly for shipping purposes. Excellent quality column that is ready to go! This column has the correct 3 5/8 inch column harness where it connects with your under dash wiring. Turn signal lever, tilt lever, and keyed ignition lock are not included. If you need more room to get in and out, this is the answer!! Comes pre-painted black just like factory units. Adding an OE style tilt column to your car will bring authenticity and value. This column will be restored to show quality and come ready to install. Works great for all 70 - 76 models with a floor shifter.
