there isnt much comparison , ive ridden the 04 yfz shocks on my friends 04 YFZ, also on a raptor, and on a banshee conversion front end, they are stiff, unforgiving, and just not very good. i bought a set of works triple rate At steelers after deciding not to do the yfz conversion, and am much happier with them, not much comparison in ride quality , the yfz's are just plain harsh riding and stiff..
the works, they are nice and soft at first and soak up all the small shit, and still manage to soak up big landings and high speed whoops and ruts with my 230+ pound ass, price is right too at around $450 for a set of triple rates with rezzies, if you arnt happy with them within 30 days u can send em back and they will revalve and/or respring them again for free
