what spring would be needed to give the 400 explorer more bottom end power, does is hurt the top end and where do you get them if I lose little top end doesn`t matter as long as I get more bottom to mid ,any other mods would you recomend

 

If you want the most low end improvement, get the green spring. If you want want something inbetween the stock spring and the green one then get the white one.
The springs are easy to change so reccomend getting the green one and if its too aggressive for your ridding style then swap it out for the white one.

I got my spring from Rick ritter at RCR..618 644 3211. He's a darn good guy to deal with and i highly recommend him.

Andy,
is 100% correct.The green spring will dramatically change your low end performance.Rick Ritter is the one to buy from as well[25$].It takes NOTHING away from your top end either.Rick is modifying a PSI pipe for me right now.Get a pipe for your Xplorer,that will REALLY wake up the beast,but it is expensive [300 dollars]Stay away from Dynoport pipe/silencer,

thanks, I just have to ask when you say the green spring may be to aggresive and may go to a white spring, does the green one make it turn up too fast? what are the diff between the two , I don`t understand , Thank you

 

According to the spec sheet,there is very LITTLE differance between the two springs,so little that I doubt you would even notice a performance differance?

The green spring makes the belt engage at a higher rpm,by doing so,it will make the belt hit tighter and faster,resulting in a much improved take-off.If you do this very in expensive mod,You'll truly be amazed at the performance differance,
Bill

 

thanks Bill and Andy
