Convert to 21" Fat Front Wheel

Convert to 21" Fat Front Wheel

Street Glide with 21 x 5.5 Insulator RYD Wheel 3

A Quick Summary

Converting your Harley Davidson Street Glide, Road Glide, Road King, etc to run a 21 x 5.5 Front Wheel isn’t super difficult, but be sure to do it the right way. We have done the research needed to know what you need to do to make this conversion. 

Buying a package deal can make your life a whole lot easier, because it’s not as simple as just slapping the big fat 21″ on and running some heavy fork oil. We have worked with hundreds of customers to help convert their Harley Baggers, from Street and Road Glides to even putting them on Softails.

#1 - Pick Out a 21 x 5.5" Wheel

Make sure you want the WIDE 21 x 5.5 wheel and not the standard width 21 x 3.75 size!, We offer both in a wide variety of styles to choose from starting at $1,499 and all of our wheels come fully assembled and ready to install! We Guarantee Fitment on RYD Wheels, Vixen Performance, & Replicator Wheels.

#2 - Get Rake Triple Trees

The 21 x 5.5 is so wide that since the tire has to be rounded, it is taller than a standard 21 inch wheel and tire. Therefore, to fit it, you need triple trees to rake your bike out properly to make up the difference of the larger 21 inch wheel. We offer the highest quality triple trees for a great price. These work great and come with a wobble free gaurantee!
