Auto Parts Suppliers Editing and Proofreading Services

A brake pad listing says it "fits most 2015-2020 sedans." A customer with a 2018 sedan orders it, and it does not fit, because "most" was doing a great deal of work in that sentence and the specific trim level with the larger brake package was one of the exceptions nobody thought to mention. The part was not defective. It was correctly manufactured for the vehicles it actually fits, and the listing's vagueness turned a fitment question with a precise, checkable answer into a guess the customer had no way to get right.

We edit what auto parts suppliers and retailers produce to specify what a part actually fits — fitment and application data, year-make-model-trim compatibility listings, OEM cross-reference and aftermarket equivalence disclosures, installation and torque specification sheets, and the customer service responses to a fitment question or a return dispute. Our editors work on the specification that has to substitute for a customer holding the part up against their actual vehicle.

The precise fitment specification is what actually prevents a wrong-part return, and its failure is an approximate description standing in for data that exists in exact form and simply was not used. Fits most 2015-2020 sedans describes a range with unstated exceptions; the manufacturer's own fitment data specifies exactly which trims, engines and option packages a part fits, and a listing that does not use it has substituted a guess for a fact that was already available. We work through these so fitment is stated by year, make, model, trim and engine or option package where these affect compatibility, since "most sedans" collapses distinctions that determine whether a specific customer's specific vehicle is actually compatible; so known exceptions within a stated range are called out explicitly, given that a range described as 2015-2020 with one mid-cycle trim change excluded needs that exception stated rather than silently absorbed into the general range; so OEM part numbers and cross-references are given specifically, because a customer trying to confirm compatibility against their own vehicle's original part number needs an exact match to check against, not a general aftermarket equivalence claim; so any installation detail that affects fit or function — torque specification, required companion parts, a design change mid-production run — is disclosed rather than assumed, since a part that fits physically but requires a specific torque or a companion part not included is a different purchase than the listing implied; so a customer's specific fitment question receives an answer confirmed against their actual vehicle identification, rather than a repetition of the general listing description; and so a return dispute over fitment is resolved by checking the customer's actual vehicle against the stated compatibility data, rather than a general assumption that the listing was probably close enough. Listings written this way turn a fitment question into a lookup instead of a guess.

Everything you send is treated in confidence, including product data, fitment specifications and customer information. We are editors rather than automotive engineers, parts specialists or fitment data providers, and we offer no view on compatibility, specifications or fitment determinations. What we can do is make sure the listing states the fitment data that actually exists.
