Made from high-grade chromium-molybdenum steel insuring increased strength and durability. Upper A arm is camber adjustable allowing for better cornering and sidehilling capabilities. Also offers much more ground clearance than stock minimizing the chance of snagging that pesky rock or stump. Light weight high strength tie rods also included. This kit is a exact replacement width for 2013-15 model Proclimb chassis but also fits Procross chassis and older Proclimbs with the 40" wide kits. This kit can also be used with a correct length shock on the 2014 Yamaha SR Viper. This kit measures 38" wide from center of spindle to center of spindle with the machine on the ground. 17" shock is ideal for this kit. Call or email if you have a fitment question. Powder coated gloss black. *If currently running a Zbroz A-Arm Kit, replacement lower or upper arms are available upon request - please call for details.
