just bought new arms for my blaster i bought +3 up 1 arms. they are made by american star sport star plus a arms. now what does the "up 1 " stand for???? does it mean it moves the wheel base forward 1 inch or does it lower the bike 1 inch???? i already bought them was just curious what that ment. i paid 440 for the complete kit off of ebay....

 

The +3 refers to the added width on each side, and the +1 means the wheel base is extended 1" forward. Where the blaster is such a small chassis, most people use a-arms that extended forward to help with the handling.

 

That is what I have on the GF's blaster. See my pictures...

 

thankyou, i thought that was what it ment but wasnt sure, thanks for your info.....
