Please note:  These wrenches are included in every Kit 1 or 2, SX-P2 TARTAN Arms, and SX-2 Camber Arms. They are sold separately in TSX-2 or 3/Y Arm purchases, since they are not essential for those arms. N2itive's Crow's Foot wrench can be used to turn the 30mm adjuster on our control arms.  You'll want to loan this wrench to the alignment tech to make their job easier. Select free shipping at checkout to save on shipping. The red version is made from light weight 6061-T6 Aluminum and is 3/8" drive. The dark gray version is made from hardened steel and is 1/2" drive. The steel version of course is more robust and will last much longer.
