Finding the best deals on auto parts doesn’t always mean driving to the local shop. For DIY mechanics and car enthusiasts, RockAuto.com has long been the go-to for “reliably low prices.” However, the real savings come from knowing how to navigate their specific promotions, rebates, and hidden clearance sections available this January.
Here are the latest deals and ways to save at RockAuto as of early 2026.
1. Instant Rebates (January 2026 Specials)
RockAuto frequently partners with manufacturers to offer “Instant Rebates.” Unlike traditional mail-in rebates, these are applied automatically in your shopping cart when you add a qualifying part.
Current high-value instant rebates include:
Fuel & Engine Management: Up to 10% off qualifying Walker Products (valid through February 28, 2026).
Bearings & Hubs: 10% off WJB wheel hubs, bearings, and seals (valid through Jan 2026).
Brake Kits: 10% off Power Stop and Raybestos brake kits (select kits).
Filters: Look for 20% instant savings on Bosch oil, air, and cabin filters.
Tip: Look for the yellow star icon next to part names in the catalog to identify these instant savings.
2. Wholesaler Closeouts: The “Secret” Clearance
The Wholesaler Closeout section is where you’ll find the steepest discounts, often reaching 50% to 80% off retail prices. These are parts from companies liquidating inventory or overstocked items.
How to find them: Select your vehicle’s Year, Make, and Model. Look for the “RSS” feed icon next to your engine size. Click that, then click the HTML “Love a Bargain?” link to see a custom list of every closeout part available for your specific car.
The Catch: Closeout parts often have a shorter return window (usually 30 days) and inventory is limited.
3. Active 5% Discount Code (January 2026)
RockAuto famously does not have a “free shipping” tier, but they almost always have a 5% discount code active. Use the latest trending code discovered by the community for the start of the year:
Discount Code:
326093150286280678How to use it: Enter the code in the “How Did You Hear About Us?” box on the checkout page. (Valid through late January 2026).
4. Pro Tip: The “Group Shipping” Hack
Shipping costs are the biggest hurdle at RockAuto because parts ship from different warehouses. To get a better deal:
Add your primary part (e.g., a Brake Rotor) to your cart.
Look for the truck icon next to other parts you need (like Brake Pads).
Choosing parts with the same truck icon means they ship from the same warehouse, significantly reducing your total shipping cost.
5. Manufacturer Mail-In Rebates
If you’re doing a major overhaul, check the RockAuto Promotions & Rebates page. These often require a form submission but offer significant cash back.
Gauges & Tools: Up to $150 back on select diagnostic tools.
Performance Fluids: Keep an eye out for rebates on Mobil 1 or Shell Rotella oils, which frequently offer $20–$100 back on bulk purchases.
Summary Checklist for Maximum Savings:
Check the Promotions page for manufacturer-specific rebates.
Use the RSS/HTML trick to find Wholesaler Closeouts for your specific car.
Group parts from the same warehouse (watch the Truck Icons).
Always apply the 5% discount code at checkout.
