Speed Dealer Customs Swingarm for 2000-2005 Harley Dyna

Product Description

Speed Dealer Customs Billet Aluminum Swingarm - Harley-Davidson Dyna 2000-2005

Transform your early Twin Cam Dyna with the Speed Dealer Customs Billet Aluminum Swingarm—a revolutionary upgrade that addresses the notorious "Dyna wobble" while delivering bagger-level engineering to the early Dyna platform. The factory swingarm uses one Timken bearing and one bushing, creating an asymmetric design that contributes to chassis flex and the dreaded mid-corner wobble. Speed Dealer Customs completely reimagines this critical component with dual 1-3/4" OD x 1" wide American-made spherical rod ends on each side—the same high-performance components used in their legendary Bagger swingarm systems. This symmetrical dual-bearing design is four times stronger than the stock setup and dramatically reduces the binding and flex that causes wobble. Machined entirely from solid billet aluminum with zero welding, this swingarm eliminates the limitations of the factory cast unit while adding weather-tight end caps with rubber seals to protect the bearings from contamination. Every component is precision CNC-machined from premium domestic materials at Speed Dealer Customs' facility, with the main arms carved from billet aluminum blocks and the axle turned from chrome-moly tubing for race-grade strength. The integrated jack spool mounts transform maintenance from a struggle into a simple lift operation, while stainless steel hardware with safety wire provisions ensures nothing backs off through aggressive riding. For early Dyna enthusiasts building performance street fighters, show bikes, or corner-carving weapons, this swingarm delivers the strength, precision, stability, and jaw-dropping visual impact that separates elite builds from the ordinary.

Why Upgrade?

The 2000-2005 Twin Cam Dyna platform delivered raw performance potential wrapped in stripped-down attitude—but the factory swingarm's asymmetric design holds it back and contributes to the infamous "Dyna wobble" that's plagued these bikes since day one. The Speed Dealer Customs Billet Swingarm doesn't just upgrade the component—it fundamentally solves the engineering flaw. Here's the critical difference: the stock Dyna swingarm uses one Timken bearing on one side and a simple bushing on the other. This asymmetric design creates uneven flex characteristics, allowing the swingarm to bind and twist under load, which manifests as the dreaded mid-corner wobble that makes aggressive riding nerve-wracking. Speed Dealer Customs engineers this swingarm with dual 1-3/4" OD x 1" wide American-made spherical rod ends on each side—the exact same high-performance components used in their legendary Bagger swingarm systems. This symmetrical dual-bearing setup is four times stronger than stock and eliminates the binding entirely. The result is transformative: sharper turn-in response, more consistent chassis behavior through bumps and corners, and dramatically reduced wobble that lets you attack twisties with confidence. The weather-tight end caps with rubber seals are essential for early Dynas that actually get ridden hard—they keep water, dirt, and road grime out of the bearings, preventing premature wear and maintaining that tight, precise feel ride after ride. By machining the entire swingarm from solid billet aluminum, Speed Dealer Customs eliminates the porosity, inconsistency, and structural limitations of cast construction. There are no welds to crack, no joints to fail—just continuous grain structure throughout the component. At approximately 13 lbs, you're shedding weight from the worst possible location (unsprung mass), allowing your suspension to work more effectively and delivering the quick direction changes that make early Dynas so addictive in the canyons. The chrome-moly axle and 8630 interference thread studs are engineered for serious use—whether you're carving mountain roads, running track days, or building a street weapon, this swingarm maintains perfect wheel alignment under loads that would flex stock components. The integrated jack spool mounts are essential for Dyna owners who do their own maintenance: flip it up on a rear stand in seconds without struggling with improvised lifting points or risking damage to freshly powdercoated frames. For builders and show bike owners, the visual impact is extraordinary—the precision machining, clean lines, and optional custom anodizing create a focal point that commands attention at bike nights and shows. Speed Dealer Customs' in-house anodizing means you can color-match this swingarm to your wheels, frame accents, or engine components for a cohesive, professional appearance. The stainless hardware with safety wire provisions isn't just aesthetic—it's race-proven security ensuring nothing backs off when you're pushing the early Dyna's limits. Installation requires a Speed Dealer Customs brake caliper bracket and an aftermarket brake caliper (not included)—the bracket mounts the caliper above the swingarm only, so plan your wheel and rotor selection accordingly. This setup uses a 3/4" axle and includes three axle spacers for proper fitment—verify your current axle size before ordering, and contact Speed Dealer Customs if your bike uses a different size. The approximately 4-6 week lead time reflects the made-to-order nature of Speed Dealer Customs components—your swingarm is built specifically for you with individual attention and quality control. Whether you're building a stripped-down street tracker, a show-winning custom, or a performance street fighter that carves corners like it's on rails while finally eliminating the Dyna wobble, the Speed Dealer Customs Billet Swingarm delivers the strength, precision, stability, and visual impact that separates elite early Dyna builds from the ordinary. This is the swingarm that transforms your 2000-2005 Dyna from good to exceptional.
