if you can keep the diff the speedo is off in your head ya can skip the speedo healer. Mines 10mph faster than I am actually running with a -1/+2

I've not had any issues with my 520 either but the 525 is stronger and should last longer.

 

thanks guys...
okay soo looking at 16 46, with a 520 if i wanna replace stock,
and 15 48 with 525 chain if i want the more low end power sweet.

sweet alright ill be looking up some kits a little lata then,

i herd that DID chains are the best is that true?

 

16/46 - 525 stock, not 520

15/48 - 520 (lighter, shorter life) or 525 (heavier, longer life) for more grunt
