Wide Tire Swing Arms

Sensible improvement, retaining style & keeping the costs down. That was our intention. So I thought what worked so well with the V-Rod, should definitely work for the new Fat Bob®… Retaining the HD swing arm. And that’s how we got our wide tire swing arm from the original. How?? Real easy: We remove your swing arm or you send us yours. Then we modify it for the XL tire. You get it back after modification with TüV Approval & freshly painted!
You have 2 versions to choose from: Big Swing and Bigger Swing. Both have the same 300mm inner width after modification. One version retains the standard length, the other is 20mm longer. This long swing arm is specially made for our new 22mm Primary Offset Kit. The belt adjusters can be retained but a longer axle is required.

Special Swing Arm "Swing Arm 300"
As you can probably guess from the title this is for the really big boys. It’s also made from the original but the internal dimensions are just a "little bit" bigger. 370mm to be precise! Monster wheels such as 300 tires on 10.5" rims can be easily accommodated by it. It’s 20mm longer and after modification it’s supplied to you with a fresh coat of paint and TüV Approval. The mega fat rubber runs in total alignment when combined with our 55mm Primary Offset Kit.
