We are the original makers of this product.  Designed and made in the USA.  Creature Racing of Sacramento California USA.  Look them up and see all the performance products they make for Chinese vehicles. 

    Unfortunately,  there are some China based companies trying to copy our kits and parts.  Made and copied in China,  but selling from some where in the USA.  These are not USA made,  are poor quality,  and for the same price.  Why support Chinese companies that copy from and steal US designers hard work,  and sell you inferior products? 

This is a custom kit for Apollo brand X4,  X5  and X6  Dirt bikes rear swing arm. 

    Otherwise known as the Apollo DBX4   DBX5   DBX6.    These are all a 110cc engine,  just different transmissions. 

The bolt is ....   m10 x 1.25 and roughly 8" long. 

A few years back,  we saw this was a weak point in the suspension of these bikes,  and decided to make a custom upgrade kit for these. 

We have a few local machine shops that we were able to contract to make most of these parts with much better materials.  These also use actual needle bearings.... not a cheap rubber bushing that squishes and falls apart.  Much more precision that stock by far!

Please do not ask if these fit other brand dirt bikes,  and other size engine Apollo bikes,  as we have no idea what other bikes would require. 

If you wonder if this bike has the same frame as yours,  contact Apollo direct.  https://www.apolloatvs.com/contact-us/
