THE Upgrade Kit for our Quik-Relaese Bumper kit. for the 350z/G35/370z
The spring is placed over the mini latch mounting stud and rests against the nut which is threaded onto the mounting stud. A retainer is placed over the ball stud, which keeps the spring from coming out of place. More pressure is needed to engage the latching mechanism, as the spring applies preloaded pressure between two mounting surfaces.
