  All swingarms being sold are now V4.  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.  We also added a machined slot on the right arm for the “one” motor and the longer shaft motors like the fw11.  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.     Updates on V4 include a much more robust brake adapter design, bearings in the swingarm as well as support notches to hold the shock mount incredibly secure in place during all types of riding!  We offer 3 versions.  With our available qs90 and qs 120 mounts, get rid of the my1020 heat issues!  Beware, the qs120 with 200 line amps is almost uncontrollable.  We have the qs90 on many bikes and reach speeds over 60 and have not had any heat issues so far.  Releasing soon is the QS165 version and we are testing the FW01 soon on that same arm.    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 the weight to be around a 500 pound spring for riders under 100 pounds, a 700-850 spring for riders around 100-175 pounds. And get a 1000-1200 pound spring for riders over 175. 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!
