Fit System Classic Round Door-Mount Side Mirror 4-3/8 in Polished Chrome Universal Replacement

Fit System 1701 is a 4-3/8” classic round, door-mount side mirror in polished chrome designed as an affordable driver or passenger-side replacement for most cars and trucks.

This compact, universal mirror brings a vintage look and straightforward functionality to vehicles with door-mounted mirror studs. Manufactured for reliability and ease of installation, the Fit System 1701 pairs a polished chrome housing with a standard mounting pattern so it can replace worn or missing mirrors on everyday cars, work trucks, and older models that need a period-correct appearance. The mirror balances style and value, arriving ready to mount with the usual hardware and backed by the Fit System/K Source reputation for automotive replacement parts.

Will the Fit System 1701 fit my vehicle’s door-mount mirror setup?

The 1701 is built as a universal classic mirror intended for door-mount applications. It fits many cars and trucks that use a single-stud or common mounting pattern, but you should confirm stud spacing and thread size before purchasing. Measurements and vehicle compatibility checks help ensure a direct swap without additional adapters.

• Mirror diameter: 4-3/8 inches (classic round profile).
• Designed for door-mount mirror studs common to older and utility vehicles.
• Polished chrome housing accommodates period styling and replacement needs.
• Check vehicle stud thread size and spacing to verify fitment.

How difficult is installation and what tools will I need?

Installation is straightforward for anyone familiar with door-mount mirrors: remove the old mirror, align the mirror base with the mount stud, and secure with the retaining nut. Typical installations require basic hand tools and usually take 10–30 minutes per side depending on access and door panel removal needs. No special electrical connections are necessary because this is a manual mirror.

• Common tools: wrench or socket set for the retaining nut.
• May require access behind the door panel for some vehicle models.
• Manual mirror—no wiring or electronic controls to connect.
• Hardware included or standard-size fasteners often compatible.

What materials and finish does the mirror use, and how durable is it?

The Fit System 1701 features a polished chrome exterior that offers a classic look with basic corrosion resistance for standard road use. The glass and housing are designed to withstand everyday driving conditions; however, long-term exposure to harsh environments will affect any chrome finish over time. For longevity, routine cleaning and protective care are recommended.

• Polished chrome housing for a classic appearance and light corrosion resistance.
• Standard mirror glass sized to the 4-3/8" round face for clear rearward visibility.
• Construction suited for daily driving and occasional utility use.
• Simple design minimizes potential failure points compared with powered assemblies.

What makes the 1701 a cost-effective choice compared with OEM mirrors?

The 1701 is an economy replacement that blends vintage styling with practical reliability at a lower price point than many original-equipment mirrors. It’s ideal when you need a dependable, affordable mirror without the added complexity or cost of power adjustment, heating elements, or vehicle-specific electronics. Fit System’s manufacturing and materials are chosen to keep costs down while providing a ready-to-install option.

• Lower price than many OEM or feature-rich mirrors.
• Simple, manual design reduces maintenance and replacement costs.
• Versatile fit for restorations, utility vehicles, and everyday cars.
• Backed by Fit System/K Source brand recognition in replacement parts.

Who is this for: The Fit System 1701 is suited to owners restoring classic cars, updating a work truck, or replacing a broken door-mounted mirror on a daily driver who wants an economical, period-correct chrome option. If you need powered adjustments, integrated indicators, or heated glass, consider a feature-rich mirror; if you want affordability, a clean vintage look, and easy installation, the 1701 is a practical choice.
