Measuring Overall Length for Custom Frame Geometry
The 22-inch length is measured strictly from the top of the rear leg to the front axle center line.
When sourcing an inline spring fork motorcycle aftermarket setup, buyers often encounter vague length claims that ignore the specific measurement method. A +4 in over stock designation means nothing if the baseline stock length differs across frame generations. Failing to confirm the exact measurement method against your frame’s springer mounting points can result in incorrect ride height and altered steering geometry [NEED_CITE: frame geometry specifications by model year].

Verifying Steering Stem and Tree Spacing
Before ordering, the 1 in inline stem diameter must be matched against your frame’s neck bearing specifications. Steering stem length and triple tree spacing vary significantly between early and late frames. Assuming a universal fit without checking these dimensions often leads to neck bearings failing to seat properly, requiring complete disassembly and re-sourcing of the front end [NEED_CITE: steering stem dimension changes across model years].
Checking Brake Drum Compatibility
The offset outside mount rockers on this kit are designed specifically for lug bolt type drum and mechanical front brake drum setups. If your custom build utilizes a different brake configuration, the mounting points on the rockers will not align. Confirming the brake drum type against the rocker mount style prevents receiving a front end that cannot accommodate your chosen braking system.
Understanding Kit Contents and Exclusions
This inline spring fork motorcycle aftermarket kit includes inner and outer springs, front and rear legs, the 1 in inline stem, offset outside mount rockers, studs, bushings, and spring rods. However, the top clamp, neck races, and cone nut are explicitly excluded. Builders must source these steering head components separately to complete the assembly, and overlooking this can halt the build process upon delivery.

The Hidden Cost of Unverified Dimensions
Ordering a custom springer without confirming the exact year range and overall length can leave a motorcycle stranded on the shop lift. I have seen instances where a +4 inch fork arrived with triple tree spacing that mismatched the frame, altering the rake and ruining the ride height. This forces the builder to either modify the frame or return the part, delaying the project and wasting freight costs [NEED_CITE: triple tree spacing variations between early and late frames].
Sourcing from a Fitment-Focused Supplier
We manufacture this front end in-house, allowing us to control the electric welded and brazed construction and chrome finish consistency across batches. Fitment is verified against your specific platform and year range before any quotation is issued. We offer a single-piece minimum order, supporting custom builders and shops working on individual projects without requiring bulk purchases.
Documentation Provided
- Fitment sheet listing applicable platforms and year ranges checked before quotation
- Key dimensions sheet detailing the 22 in overall length and 1 in stem diameter
- Cross-reference sheet with OEM numbers marked reference only
- Finish specification confirming chrome application on legs, springs, and rockers
- Quality inspection record covering weld integrity and bushing fitment
Pre-Installation Checks
- Verify the 22 in overall length matches your frame’s springer mounting requirements
- Confirm the 1 in inline stem diameter aligns with your available neck races
- Check that the offset outside mount rockers match your lug bolt type drum setup
- Inspect the chrome finish on the front legs and outer springs for batch consistency
- Ensure all excluded items like the top clamp and cone nut are sourced separately
Requesting a Fitment Check
Send your exact model and year, along with a photograph or measurements of your current steering stem spacing, to verify compatibility. Specify if you need this 22-inch configuration or require a different over-stock length for your custom geometry. We can also arrange a sample supply for fitment confirmation before you commit to a bulk order for your shop.
Frequently Asked Questions
Q: How is the +4″ over stock length measured on this inline spring fork?
A: The 22-inch overall length is measured strictly from the top of the rear leg down to the center line of the front axle. This specific measurement method ensures you can accurately calculate the ride height and steering geometry impact on your custom frame, rather than relying on vague industry estimates.
Q: What steering head components are excluded from this fork kit?
A: The top clamp, neck races, and cone nut are not included in this kit. The package contains the springs, legs, stem, rockers, studs, bushings, and spring rods. You must source the excluded steering head components separately to complete the front end assembly for your build.
Q: How do I confirm this 22″ fork will fit my specific custom frame geometry?
A: You must verify the 1-inch inline stem diameter and the triple tree spacing against your frame’s neck bearing specifications. Additionally, confirm that the 22-inch overall length matches your desired ride height. Providing your exact model and year allows us to check these dimensions before quotation.
Q: Can I order a single fork kit for a custom build without a minimum order quantity?
A: Yes, we support a single-piece minimum order. This allows custom builders, chopper shops, and independent restorers to purchase exactly what they need for a specific project without being forced to buy in bulk or meet high quantity thresholds.
Q: What brake drum types are compatible with the offset outside mount rockers?
A: The offset outside mount rockers are designed to accept lug bolt type drum and mechanical front brake drum setups. If your build uses a different brake configuration, such as hydraulic disc conversions requiring specific caliper mounts, you must verify compatibility with the rocker mounting points before ordering.
