Speedway Motors Weld-On Panhard Behind Rear End Bracket
The Speedway Weld-On Panhard Behind Rear End Bracket is designed for rear suspension systems that use a Panhard bar behind the axle. It fits standard 3-inch axle tubes and includes six 3/4-inch adjustment holes to fine-tune roll center and bar angle. This enables precise lateral axle positioning and alignment with a welded-on mount.
Best for: racers and builders with a defined rear chassis geometry who need multiple hole options to dial in handling. It’s particularly suitable for custom rear suspensions that require secure weld-on attachment and repeatable alignment.
Caution: Welding quality and proper tube preparation are essential; improper welds can compromise mounting strength and alignment. Ensure the bracket is positioned to avoid interference with other suspension components.
Universal Weld-On Rear Panhard Bar Track Rod Kit (Speedway Motors)
This universal kit targets multiple parallel-mount suspensions and helps control lateral axle movement for coil spring or coil-over rear setups. It includes a 22.5″ Panhard rod, 7/8″ DOM tubing, 5/8″ rod ends, and weld-on brackets. The rod ends are left- and right-hand threaded for straightforward on-car adjustments, aiding axle centering within the body.
Best for: builders seeking a complete, on-car adjustable Panhard solution compatible with a wide range of coil-spring or coil-over configurations. This kit provides robust components and on-car adjustability to refine alignment.
Caution: As a universal kit, fitment checks are important; ensure the rod length and mounting positions match your chassis to avoid binding or excessive rod angles.
Clamp-On Behind Rear End Panhard Bar Bracket (Speedway Motors)
This clamp-on bracket is designed for 3-inch axle tubes and offers an adjustable mount setup without welding. It features four 3/4″ mounting holes to adjust panhard bar angle and roll center, supporting improved handling on a wide range of chassis. The heavy-duty steel build provides durability for racing, off-road, or custom street use.
Best for: users who need a flexible, non-weld solution that can be removed or repositioned as needed, such as temporary builds or test vehicles. It’s an option when welding is not feasible or desired.
Caution: Clamp-on mounting can introduce movement under extreme loads; verify bolt torque and clamp tightness after initial driving to maintain alignment.
Set of 4 Heavy-Duty Weld-On Axle Tabs (Core Logic)
These heavy-duty weld-on tabs are designed for universal 4-link suspensions, shocks, sway bars, and ladder bars, offering versatile mounting points with a five-inch tab length. They are ready to weld directly onto the axle housing or frame, enabling custom suspension geometry with reliable strength.
Best for: builders who want a flexible, strong mounting point for multiple suspension components in 4-link configurations. The 5″ length provides ample surface area for fusion with the axle housing or frame.
Caution: Ensure proper alignment before welding to avoid off-angle mounting that can degrade suspension geometry.
2-Pack Weld-On Axle Tabs – 5″ Tall x 1/4″ Thick (Core Logic)
This 2-pack provides 5″ tall, 1/4″ thick weld-on tabs suitable for 4-link suspensions, shock mounts, sway bars, ladder bars, and panhard bars. The heavy-duty tabs are designed for direct welding to axle housing or frame, enabling reliable, robust mounting for performance builds.
Best for: projects needing a compact two-tab kit with strong attachment points, suitable for consistent mounting across multiple suspension components in a single build.
Caution: Check exact fitment with your axle diameter and ensure proper welding technique to avoid heat distortion or mounting weakness.
Weld on Tabs – 4-Pack, 1/2″ Hole (OywhC)
OywhC’s weld-on tabs are carbon steel, featuring a 1/2″ mounting hole and compact 2-11/16″ height with 2-4/9″ width. The 1/4″ thickness yields a sturdy, versatile mounting point for various projects beyond automotive, including industrial uses.
Best for: DIY fabricators who need reliable, simple tabs with standardized dimensions for multiple mounting jobs, including small-scale suspension or accessory mounts.
Caution: The listed dimensions may have minor tolerances; verify measurements before welding to ensure correct fitment for your assembly.
Set of 4 Radius Weld-On Axle Tabs (Core Logic)
These radius weld-on tabs are designed for 3″ to 3.5″ diameter axle tubes with a 1/4″ thickness. The five-inch length supports 4-link suspensions, shocks, sway bars, ladder bars, or panhard bars, providing a versatile mounting platform with strong surface area for welds.
Best for: builds requiring robust radius tabs that can handle multiple suspension components while maintaining clean geometry and alignment.
Caution: Match the tube diameter precisely; misalignment can affect the tab’s load path and overall geometry during operation.
Buying Guide: Key Considerations And Practical Comparisons
- Installation type: Weld-on mounts offer permanent strength and repeatable alignment; clamp-on options provide flexibility without permanent modification.
- Tube compatibility: Check axle tube diameter (commonly 3 inches) and tube wall thickness to ensure a proper fit and secure welds.
- Adjustment options: More holes or adjustable rod ends enable fine-tuning of roll center and panhard bar angle; plan how much adjustability you need for your setup.
- Material and build quality: Look for heavy-duty steel with consistent fabrication to withstand racing or demanding off-road use.
- Avoiding interference: Ensure mounting points do not collide with exhaust, fuel lines, or suspension links during full compression and steering lock.
- Future flexibility: If you anticipate multiple configurations, prioritize universal or multi-component tabs that support 4-link, ladder bars, sway bars, and pans.
