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
it's a perfect fit, looks way better in person, wish they added a kickstand with it but overall clean swing arm, fast shipping great service I would buy from them again!!

Polished it up added a kick stand, can’t wait to run it!
These look great and is a great design! My kid dropped one on concrete and it dented an edge, kinda bummed but after taking mothers polish to it, you can’t really tell and they loo great! Hope they work just as well as they look.
