Change your TRA clickers 2,3,5 & 7 in seconds. The quick clickers are the same as a stock cam profile and can be adjusted without loosening the lock nut. The 1/2 click quick clickers in the #3 position is the same as stock, but each click up or down moves the ramp 1/2 as much as stock, and can be done without loosening the lock nut. The 1/2 click clickers are the same as above, but you will need to loosen the lock nut to adjust like the stock clicker. Great for fine tuning adjustments.
