I am looking for the length of the stock fork spring and the length of the Progressive fork spring. Thanks.
Does that make the Progressive spring 3.3" longer than the stock spring?I measured the stock spring's free length to be 490 mm.
The Progressive Suspensions spring has a free length of 572 mm with a rate of .45-.71kg/mm, btw.
Besides Race Tech, straight rate springs are also offered by Sonic Springs, Noleen J6, and Cogent Dynamics as well. Noleen J6 and Cogent are possibly selling Race Tech springs, but Sonics are made in-house. They offer both a .48kg/mm and .52kg/mm and can make custom rates.
