is there ones with short and ones with long springs i was looking on ebay and some look long and some look shorter
unless you are looking at a front and back shock. The back shock is going to look shorter than the front and even shorter than a stock blaster rear.
L-R Blaster, Banshee, YFZ450, LTR450
Shows length comparisons. Even though it doesn't look like it, all upper mounting locations are even.
I am told a yfz450 shock bolted to a banshee or blaster will trash your ball joints and eventually your wheel will come flying off. (maybe at high speed)
I'm not to bright... I did it on my banshee anyway.
