    Torsion bars

    if its a 2011 and up you don't need them just crank up your torsion bars 4 turns your good to go. If it is a 2010 an down crank them all the way. this is my 03 with a blizzard 810. The hd torsion bars just start off where you would be with your standards cranked up iphone 326.jpg

    I think HD denotes High Density. They won't float in water so we know the Specific Gravity is >1
