Custom length driveshaft RFQ checklist

RFQ Checklist decision points

Product

Name the custom length driveshaft family, one-piece or two-piece layout, flange bolt pattern or spline series, tube material and the measurement endpoints (flange-to-flange, compressed or working). Provide OE reference only as an identification aid.

Quantity

State count on a pieces-by-position basis and list whether yokes, U-joints, CV boots or a center support bearing travel with the assembly. Minimum order quantity is a supplier answer, not a figure invented here.

Destination

Include country, US state or ZIP, requested timing and, if already chosen, Incoterms. Gross package weight and packing unit affect freight comparison and should be requested with the quote.

Open choices

Note optional budget (currency and per-unit or total-order), supplier preference (high-end, mid-range, budget, undecided) and remaining suspension-height or balance questions. Preferences are buyer trade-offs, not verified factory grades.

Measurement datum, not assumed length

Agree whether the vehicle is on the ground, on a hoist or at ride height before recording compressed or working length. Ask for a marked drawing showing the endpoints used to state the offered length. Balance evidence and joint series must bind to that same drawing revision. Sample approval should record the sample identifier; later lots still need agreed inspection points.

Specification files to request

Flange-to-flange or compressed length with the measurement endpoints marked on the drawing (mm or in).

Joint series and bolt pattern identifiers, plus spline or flange interface details.

Operating speed range and the balance evidence bound to that exact assembly revision.

Packing unit, gross package weight and whether yokes or U-joints travel with the shaft.

Optional target budget in USD per piece or total order, and a buyer preference for high-end, mid-range, budget or undecided suppliers.

This checklist does not assert that Shaftscope Sourcing owns tooling, a laboratory or completed factory audits. Custom geometry may be declined by a plant; that outcome is a supplier decision. Agricultural PTO, garage-door and motorcycle shafts stay outside this RFQ.
