Why Superseded Numbers Cause Front-End Delays
Confirm fitment by platform and year range before ordering these bracket bolt washers for big twin builds.
Part numbers change across model years, meaning a number from an older manual might no longer match the required hardware for a late-model frame. When a shop relies on outdated cross-reference data without verifying the specific platform, the front-end assembly halts because the washers do not align with the bracket bolts. This mismatch forces the builder to pause the project and reorder the correct pair, delaying the entire chassis setup [NEED_CITE: superseded part number changes across big twin model years].
Verifying Platform Exclusions for Big Twin Models
When sourcing bracket bolt washers for big twin applications, the year range and model exclusions dictate whether the hardware will physically seat correctly. These chrome plated washers fit all Big Twin models from 1978-later, but they are explicitly excluded for FLT models and Dyna models from 2006-later. Overlooking these exclusions often happens when builders assume a universal fit across the entire big twin family, leading to spacing issues at the fork brackets. Checking the exact model year against the exclusion list ensures the pair matches the specific triple tree and slider configuration [NEED_CITE: bracket bolt spacing variations between FLT and standard big twin frames].
Chrome Plating and Batch Consistency
The chrome plated finish on this pair is checked for visual consistency, ensuring both washers match when installed side by side on the front end. In aftermarket front-end hardware, finish variations between batches become highly visible once the forks are assembled and exposed to light. By verifying the chrome plating quality before quotation, we prevent situations where one washer looks noticeably different from the other, which is critical for custom builders aiming for a uniform front-end appearance.
Understanding the Pair Quantity and Finish Specs
These bracket bolt washers for big twin setups are supplied as a pair, providing the exact quantity needed for a standard front bracket assembly. The chrome plated finish is specified to match other front-end hardware, ensuring the washers do not stand out against the sliders or triple trees. Because the pair quantity is fixed, builders must verify that their specific rebuild requires exactly two washers for the bracket bolts, avoiding the need to source mismatched singles from different suppliers.
The Hidden Cost of Incorrect Bracket Hardware
Ordering the wrong washers based on an incomplete fitment chart often leaves the motorcycle stranded on the shop lift. If the bracket bolt washers are too thick or too thin for the specific big twin year, the fork brackets cannot be torqued correctly, leading to misalignment in the front end. This forces the mechanic to disassemble the front end, measure the original hardware, and wait for the correct pair to arrive, wasting labor hours and delaying the customer’s build [NEED_CITE: front end alignment issues caused by incorrect bracket hardware thickness].
Sourcing Fitment-Checked Front End Hardware
We verify the fitment of these bracket bolt washers against the specific big twin platform and year range before sending a quotation. Our team cross-references the HD# 5710 to ensure it matches your model, explicitly checking that your bike is not an excluded FLT or a 2006-later Dyna. We offer a one-piece minimum order, meaning you can order a single pair for a custom build without meeting high bulk thresholds. Every front-end part is checked for chrome and black finish consistency to ensure visual matching on the bike.

Receiving and Pre-Installation Checks
- Verify the pair quantity matches your front-end bracket rebuild requirements
- Check the chrome plated finish for any shipping damage or plating defects
- Confirm your model year is 1978 or later and not an excluded FLT or 2006-later Dyna
- Compare the physical washers against your original bracket bolts for thickness
- Store the hardware in a dry environment to prevent surface corrosion before installation
Request a Fitment Check
Send your specific big twin model and year to verify that these bracket bolt washers fit your front-end setup. Provide the original bracket bolt dimensions or a photograph if the part number is unknown, and specify if you need the chrome plated finish. We can also supply a sample pair for fitment confirmation before you commit to a larger order for your shop.
Frequently Asked Questions
Q: How do I confirm my big twin model is not excluded from this fitment?
A: Check your motorcycle’s model year and specific platform. These washers fit all Big Twin models from 1978-later, but they are strictly excluded for FLT models and any Dyna models from 2006-later. If your bike falls into these excluded categories, you will need a different part number for your front-end brackets.
Q: Can I order a single pair of these washers for a custom build?
A: Yes, we support a one-piece minimum order. You can order a single pair of these chrome plated bracket bolt washers for your specific one-bike build without needing to meet a high bulk quantity threshold, making it ideal for independent repair shops and custom builders.
Q: What should I do if my old manual shows a different part number?
A: Part numbers are frequently superseded across model years. Send us your model, year, and a photo of the old hardware. We will cross-reference the current fitment against your specific big twin platform to ensure you receive the correct pair for your 1978-later front-end assembly.
Q: Will the chrome finish match my other front-end hardware?
A: The chrome plating on this pair is inspected for visual consistency to match standard front-end hardware. We check the finish quality to ensure both washers look uniform when installed side by side on your fork brackets, preventing mismatched aesthetics on your custom build.
