We upgraded to the 3 wheel kits because the 2 wheel kits are just not standing up, you may want to look into it especially if you are jumping a bit. The 07's had them stock, it wont cost you much and it will be stronger. I actually went to 4 wheeels in the back again and notice no difference in any way including side hilling, the 2 wheel looks cool but it is not beefy enough from the factory. If you are determined to keep 2 wheels only, Mountain Magic in Edmonton makes a heavier kit, I think it is around $120.00.
