First, should i get an extended swingarm for my blaster?

Second, what will it do?

Third, what size should i get?

 

A longer swing arm will help you keep the front end down under hard acceleration(sp?) You will be able to climp steeper hills. since you don't have to lean as far forward while going up hills, you can keep more weight over the rear tires where it will make traction. The blaster will handle whoops alot better. You will notice a slight decrease in turning diameter.
