hey folks my uzzi slx has a vanilla rc i've been wanting to upgrade the shock for sometime. what size 5th will fit my frame and whats the cost of the upgrade

The SLX takes a 2" stroke, 7.5" eye-to-eye shock. Progressive's retail price is $432 for a 5th Element - without spring.

7.5" X 2" stroke is the size. You will need to make sure its 2002 or newer frame. I think the piggyback will not clear the earlier seat towers but intense can modify the frame to fit it if its a 2001. www.aebike has the shocks for like $350 and coils for about $38. You will also need the mounting hardware. Its not the same as the Fox mounting hardware. Check the progressive fit list for the proper spacers.
