Which shifter should I choose? If you're looking for quicker shifts and improved performance from your manual S550 Mustang, you may consider upgrading to a Hurst Shifter. Hurst Performance currently offers two options to improve your experience when slinging gears, the Hurst Indy Shifter (Part # 3916036), and the Competition/Plus Shifter (Part # 3916037). Which may leave you wondering, "Which shifter is right for me?" Indy Shifter (Part # 3916036) The Hurst Indy Shifter can be thought of as an entry level shifter that provides a noticeable 18% reduction in throw and a firmer, crisper feel, all while retaining the factory reverse lockout collar and function. The Indy Shifter includes a replacement stick, reverse lockout slider, urethane rear mount, and a classic black Hurst round ball knob. Additionally the Hurst Indy Shifter is backed up by a Lifetime Limited Warranty. Competition/Plus Shifter (Part # 3916037) The Hurst Competition/Plus Shifter on the other hand is the premium option. The Competition/Plus shifter utilizes a multi-link-type mechanism to achieve the perfect combination for a short throw shifter, reducing shift throw by 38% from front to back, while maintaining a smooth silky side-to-side shift that is barely reduced resulting in close to full side-to-side resolution. Additionally, these shifters feature a billet steel, chrome plated upper stick with reverse lockout trigger, and a classic white knob to properly accentuate the interior of your Mustang. The Competition/Plus shifter also gives the piece of mind and assurance of a Lifetime Limited Warranty. Whether it be the Indy Shifter or the Competition/Plus, both shifters share similar installation times, and both carry Lifetime Limited Warranties. Making the deciding factors largely depend on your personal performance and appearance preferences, as well as budget.
