2025 MEMA Aftermarket Replacement Rates Report

The expanded 2025 MEMA Aftermarket Suppliers Replacement Rates Report covers the expanded 13 product categories and 181 aftermarket parts that we did last year, more than double the number of parts of earlier reports. With this expansion, you will now see replacement rates for select parts that drive ADAS and EVs.

Easy to use, convenient format! This report is delivered in an Excel Workbook for a more convenient experience and to enable you to more easily pull data from it or work with the data right in the workbook itself. Based on the percentage of private vehicles receiving specified maintenance, you can use this report to calculate product durability, market size estimates and service job variables.

Replacement Rates Explained. The replacement rate is the percentage of all privately-owned light vehicles on the road that received a specific repair or service job. MEMA’s replacement rates are derived from more than 100,000 households surveyed annually by IMR, Inc.

Trends in replacement rates over time are very important, and the MEMA Aftermarket Suppliers Replacement Rates Report is the only aftermarket publication that depicts a three-year trend in replacement rates.
