Yamaha YFZ450R High Clearance Pro MX A-Arms

Introducing our all-new YFZ450R High Clearance Pro MX A-Arms! We’ve completely redesigned our YFZ450R Pro MX A-Arms with updated geometry, increased adjustability, and improved durability while maintaining the same lightweight performance. What’s New: Updated Geometry – Our new Pro MX A-Arms feature a revised geometry with a new MX width of +7/8” per side (1-3/4” wider overall than stock). This nets you a true 50" wide machine on 4+1 wheels. They also offer adjustable forward/rearward placement, allowing you to run -3/8” rearward, centered, or +3/8” forward using the included spacers. These arms continue to use the same 20” extended-length shocks as our previous DC-Pro A-Arms, although shock valving will need to be changed to match the updated geometry. New Quick Camber Upper Ball Joint Design – The upper A-Arm features an all-new ball joint boss that still accepts the tried and true FRAP ball joints while providing significantly more adjustment. This means more ccompatibility with a wider range of front-end setups. There is enough adjustment to run stock spindles or LTR spindles without changing the upper arm length. A key feature of this design is it still allows you to adjust the ball joint without removing it from the spindle. Completely Redesigned Lower Arms – The lower arms now feature a fully boxed-in shock mount for added strength, along with a high-clearance bend that maximizes ground clearance and helps protect both the shock mount and A-Arms from rocks and ruts. New Greasable Polyurethane Bushings – We’ve replaced the previous pivot bearings and Delrin bushings with our new greasable polyurethane bushings. These bushings offer exceptionally long service life while adding a small amount of compliance to help absorb impacts and reduce maintenance. 4130 Chromoly Construction – Built from premium American 4130 chromoly steel and fully TIG welded for maximum strength and reliability. Shock Compatibility – Designed with plenty of clearance for all aftermarket shocks with a 20” extended-length. A 20" shock will provide a full 11" of wheel travel. Caster Correction Included – Each kit includes our proven caster corrector bracket and caster spacers for proper front-end alignment. New Lower Shock Bolt Dust Caps – We’ve also added billet dust caps to the lower shock bolts to help prevent mud and debris from building up inside the mounts. 20" EXTENDED LENGTH 5.5" SHAFT TRAVEL 2.00 TO 1 LEVERAGE RATIO 11.00" WHEEL TRAVEL 2.5" OF GC WITH 20" MX TIRE BIKE APPROX 410 LBS WET
