The Top-Selling "Must-Stock" Parts for Rehlko/ Kohler 

These are the most frequently sold and searched-for items, essential for routine service and common repairs.

  1. Filters (The "Big 3")

    • Air Filters & Pre-Cleaners: This is arguably the most common replacement part. Stocking the primary air filters and their foam pre-cleaners for popular engine series (like Command PRO, Courage, 7000 Series) is essential.

    • Oil Filters: A core maintenance item. The "yellow" Kohler oil filters (like parts 12 050 01-S and 52 050 02-S) are iconic and move quickly.

    • Fuel Filters: In-line fuel filters are a quick and easy upsell during any tune-up and a frequent fix for fuel delivery problems.

  2. Ignition & Fuel System

    • Spark Plugs: A standard tune-up component.

    • Carburetors & Carburetor Kits: Complete carburetors are a high-demand, higher-ticket item for engines left with old fuel. Carburetor repair kits (which include gaskets, needles, and seats) are also very popular.

    • Ignition Coils (Modules): A common failure point and a top-searched item for "no-spark" conditions.

    • Fuel Pumps: Especially for v-twin engines, these are a common replacement part to fix fuel starvation issues.

  3. Kits & Engine Hardware

    • Maintenance Kits: These are extremely popular as they bundle an air filter, pre-cleaner, oil filter, fuel filter, and spark plugs into one package. They are a great, simple item to sell.

    • Gaskets: Head gaskets, carburetor gaskets, and exhaust gaskets are always in demand for more in-depth repairs.

    • Starters: Both electric starter motors and starter solenoids are frequently replaced parts.

How to Use This for Your Annual Return

When you prepare your offsetting order for the parts exchange, your goal is to swap your "dead stock" for these "guaranteed movers."

  • Your Return List: The old, model-specific part that's been on your shelf for two years.

  • Your Offsetting Order: A fresh stock of the high-demand air filters, oil filters, spark plugs, and maintenance kits you know you will sell during the next busy season.

This strategy ensures you are using the return program to its full advantage: clearing out non-performing assets and acquiring fast-moving inventory without spending new cash.
