This is a pair of Integy Purple Aluminum Adjustable Upper Suspension Arms for the HPI Savage X, XL, 21, 25, and SS trucks.  This upper arm will allow Savage owners to tune the front and rear camber of their trucks. These work on the front or rear of the truck.  To upgrade both the front and rear, purchase a quantity of "2" sets of these.  With thick steel turnbuckles and hand polished aluminum arms, this is the perfect addition to any racing Savage.  These are very strong, and they are a must for a serious Savage owner.
