When im riding my sled(phazer) it is not as stiff as i would like...I am a 175 pound person and im riding with stock springs. i would like to stiffen up the back suspension. What i am wondering is if they make a two-up spring for a Phazer...i checked with a parts dealer and they told me i could get heavy duty springs for 40 bucks each, which i would rather not spend...does anybody know anyone with springs for sale or have information on two-up springs?? thanks for any information.
