All swingarms being sold are now V5. This newest version has all sides of the arms machined for more finished look (not perfect, expect some machining marks) and we updated the shock brace to a solid, one-piece design along with updated mounting points for the new GTS11 and FW11 mounting system. The brake adapter has been updated as well which changes the angle of the caliper to allow for a cleaner install of the brake line. Another change adds a larger machined slot on the right arm for the “one” motor and the longer shaft motors like the fw11, we also lengthened the slot to accommodate a belt drive pulley. The 3” arm will NOT fit a 12” wheel! You must buy the 5” for a 12” tire!
Custom designed , CNC machined aluminum swingarm upgrade for the Razor SX500 and MX500/650 made right here in Minnesota. This offers roughly a 3in extension from stock swingarm length, it also includes adjusted shock placement, and ability to adjust the rear wheel so there is no need for a chain tensioner! Brake adapter is stock razor size. The stock brakes will not fit with the zoom adapter. You will need zoom or pit bike brakes. Our pit bike brakes will now work with stock razor wheels with optional adapters we make and sell.
Please note we have only fully tested this swing arm on the SX500 with 260 and 280mm shock. You will need a full size pit bike shock that we offer or are available elsewhere like amazon and eBay. Please make sure you have a shock that has an m10 hole. We have found that the weight for riders under 100 pounds should shoot for the 800 pound spring and grab the 1000 pound if over 100 pound rider weight. We offer spring rate adjustment tools with our shocks also. VERY IMPORTANT---Make sure to use thread lock on all bolts that do not have a nut on them! Please do not powder coat these arms, the tolerances are much too tight and leave absolutely no space for any additional thickness, not even a fraction of a millimeter!
This kickstand works, it's not perfect but gets you going! Heavy duty plus, and 40mm option

Best swing arm
Everything went together super easy and as it should, the performance and quality on this product is amazing!
Swing arm worked great on my SX500. No issues, allowed me to jump to a 12" on the rear and 14" on the front (using Ride or Die forks).
Fantastic quality but there was no manual included hence the denotion of one star. No videos covered the FW11 interface and mounting. I am still unsure if I only use the cradle to mount my motor. A issue, a star.
fit perfect, raised the height, with the shock from bill everything rides so good! the quality is top notch, and it looks SO good!
