Zodiac Softail Swingarm Kit for Up to 300 Tires – Frame & Rear Suspension

How can one fit a 270, 280 or even 300 in a stock Softail frame? Simple, that's where Zodiac comes in. Zodiac's Ton Pels designed a complete extra wide swingarm kit that includes a "no jig needed" frame widening kit as well as the primary offset kit that allows the use of up to 300 tires in stock and most aftermarket frames. The frame widening is done with a 15mm. thick offset banana shaped frame side plate. The banana shape side plate is welded in to place using the original banana plate as the welding jig. The location of the engine/transmission of the Evolution models in the frame has a 1/4" difference compared to the Twin Cam models. Therefore the offset in the frame plate, in combination with our 45mm primary offset kit provides enough room for up-to 250 series rear tires in Evolution Softail frames, and 280 series rear tires in Twin Cam Softail frames. If the offset plate is used in conjunction with our 55mm primary offset, the kit provides enough room for Avon's extreme wide 300 series tires in a 2000 thru 2006 Twin Cam Softail frame, or Metzeler 280 series rear tire in an Evolution Softail frame. The offset plate with 25mm primary offset kit for 2007 to present models provides enough room to install a 280 series rear tire.

The complete kit contains a swingarm, offset banana frame side plate and a very complete primary offset kit. Primary offset kit for models thru 2006 includes primary spacer ring with support bearing, crankshaft extension, extension nut, primary gasket kit, extended main shaft, extended main drive gear, offset front pulley, extended starter motor coupler with extended bolt and all extended primary bolts with locking plates. Primary offset kits for 2007 to present contain a primary spacer ring without support bearing. The OEM brake caliper can be re-used. and tabs for the belt guard are welded in place. The kits for Evolution Softail must be used with a Twin Cam type 1 1/8" wide, 135 tooth final belt and a 70 tooth 1 1/8" wide pulley. When installing this kit in a 1991 thru 1993 model a late style countershaft 5th gear (ZPN237074) must be ordered separately. For selected models we have complete kits that include a complete 6-speed conversion too.

Note: We strongly recommend a craftsman or certified welder does the welding of the side plate. When needed, Zodiac can arrange the welding for you. Just ask your Zodiac dealer.
Note: The Evolution models will accept the 300 series tire if the wheel is slightly offset to the right side.
Note: We designed a special 29 front, 65 rear pulley and belt combination to create extra belt clearance on extremely lowered bikes. Check this out in the rear belt and pulley section.
