Lonestar Racing LSR NEW YFZ450R HIGH CLEARANCE XC A-ARMS Yamaha Yfz450r

We are extremely excited to introduce our all-new High Clearance Yamaha YFZ450R XC A-arms!

We took every recommendation from our top racers as well as any complaints we've received from them and all other customers, piled it all together and built what we believe to be the best set of XC a-arms available for the YFZ450R. 

Here is what we came up!

We kept the same geometry as the old-style DC-Pro's with the same XC width of -1 1/8" narrower per side with no forward placement. So there's no need to modify your shock tuning. Customers that are switching over from Houser arms will also be able to reuse their same shocks.

Completely redesigned the lower arm to feature an entirely boxed in shock mount while also including a high clearance bend to achieve maximum ground clearance. That means the bottom of your shock is safe from everything on the trail as are the arms themselves.

We got rid of all of the pivot bearings and delrin bushings and replaced them with our new greasable Polyurethane bushings in order to extend service intervals (these bushings last an insanely long time) and provide extra cushion between the trail and the rider as the poly bushings have more give compared to delrin or bearings

Arms are made out of 4130 Chromoly and are completely tig welded

Still requires the use of a 20" extended length shock

The weight of these new arms is the exact same as the old style, so you are gaining more strength while not adding any additional weight.

Shock mount has clearance for all aftermarket shocks

Kit still includes our tried-and-true caster corrector bracket, and caster spacers

We are also now including dust caps for the lower shock bolt to prevent mud from building up inside.
