Swapping springs in shifter takes about 2 minutes:
The socket-headed screw in the center, between the two button-head cap screws, covers the right side bias spring cavity. The screw height is the fine bias spring adjustment. To make a large change in bias spring tension, you remove the screw and change the spring.
Now, make a preliminary bias spring adjustment. Bias springs are what you feel working against you as you pull the shifter left, into the 1-2 gate, push it right, into the 5-6 gate, or push it far right, into the reverse gate. There is a bias spring on each side of the shifter and each of these springs can actually be two springs, one inside the other, or a single spring.
The Hurst’s bias spring adjustment can be accomplished at two levels. There is a “coarse” adjustment made by changing springs (six are included with the shifter and a combination of two per spring position is how the Hurst comes from the factory) and there is a “fine” adjustment, accomplished with adjustment screws which vary the installed height of the springs.
Bias spring adjustment can be somewhat subjective. Fortunately, the engineers at Hurst were astute enough to give the user a wide choice. Drag racers are going to probably want high spring tension. At the opposite extreme are persons who might lack arm muscle strength, particularly when pushing the shifter way right to get the reverse gate. In the latter case, you might want to start with a spring change to the two lowest tension springs.
It is important to note that, in the C5 aftermarket shifter market, the Hurst is the only product which allows the user to remove the bias springs without completely disassembling the shifter. Also, Hurst is the only manufacturer to include the additional springs for variety and the freedom of adjustable spring preload. With other shifters, users often remove the springs and cut a few coils off to change preload, but they can't vary the rate. This is an important and desirable feature of the Hurst shifter that puts it ahead of all others on the market
