Lone Star Racing High Clearance Long Travel A-Arms

--XC 2009-2026 YFZ450R Specs:

• LSR kept the same geometry as the popular -3/4" DC-Pro XC a-arms, so modifying your shocks for high clearance a-arms is unnecessary. Customers switching over from Houser's XC YFZ450R arms will also be able to reuse their current shocks.
• LSR completely redesigned the lower arm to feature an entirely boxed-in shock mount to keep your lower shock safe from debris.
• The high clearance decreases the stress on the lower a-arms from debris.
• These HC a-arms come standard with greaseable polyurethane bushings to extend service intervals.
• LSR Arms are made out of 4130 chromoly and are completely tig welded for maximum durability.
• The weight of these new arms is the same as the XC Pros, while you're gaining more strength you're not adding any additional weight.
• Shock mount has clearance for all aftermarket shocks ( Axis, Elka, Fox, Motowoz, and PEP)
• Kit still includes LSR's tried and true caster bracket w/caster spacers.
• LSR includes dust caps for the lower shock bolt to prevent mud and dirt build up.

--MX 2009-2026 YFZ450R Specs:

• LSR Pro MX A-Arms feature 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 using 4+1 wheels.
• Adjustable forward & rearward placement by utilizing the included spacers (-3/8” rearward, centered, or +3/8” forward).
• Uses the same 20” extended length shocks as the previous DC-Pro A-Arms. Although, valving will need to be updated to match the new geometry.
• Upper A-Arm features an all-new ball joint boss that still accepts the race proven FRAP ball joints while providing significantly more adjustment.
• This design offers the ability to adjust the ball joints without removing it from the spindle.
• 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, washouts, and ruts.
• Delrin bushings bushings offer exceptionally long service life while adding a small amount of compliance to help absorb impacts and reduce maintenance.
• Built from premium American 4130 chromoly steel and fully TIG welded for maximum strength and reliability.
• Includes the proven caster bracket and caster spacers for proper front end alignment.
• LSR has added billet dust caps to the lower shock bolts to help prevent mud and debris from building up inside the mounts.

--2004-2014 TRX450R Specs:

• The DC HC arms are 1.5" wider per side with Zero forward placement for better cornering!
• New polyurethane upper bushings in place of the heim joints to extend service intervals.
• Caster can be quickly adjusted for different conditions by moving the clips from front to back. This adjustment is easily accessible by simply loosening the upper A-arm bolts from front to back to increase or decrease caster for different conditions.
• LSR completely redesigned the lower arms for more ground clearance and to protect the lower shock eyelet from debris.
• LSR High Clearance A-Arms are made from 4130 Chromoly and are completely tig welded for maximum strength.
• Shock mount has clearance for all aftermarket shocks.
• Includes front shock mount plugs to prevent mud/dirt build up inside the shock bolt hole
• Kit includes all new frame side hardware.

--XC TRX450R Notes:

• You can reuse your original LSR DC XC shock setup but they will need some fine tuning to offset the new +1.5" with 0 forward placement design.
