Why Aftermarket Hydraulic Breaker Parts?
Aftermarket hydraulic breaker parts are manufactured by independent producers to the same dimensional tolerances, material grades, and hardness specifications as OEM components. For high-wear items like chisels, bushings, and seal kits - which need to be replaced regularly regardless of brand - aftermarket parts deliver equivalent service life at a fraction of the OEM cost.
Big Hammer Co sources parts from manufacturers that meet the material and hardness standards required for hydraulic hammer service. Every chisel and point in our catalog is produced from tool steel with hardness specifications appropriate for the target breaker model. Seal kits are matched to the OEM drawing dimensions for the specific hydraulic circuit they service.
We do not carry low-grade commodity parts. Our focus is on the middle market: quality aftermarket components priced well below OEM, backed by a team that knows hydraulic breakers - not just part numbers.
How We Work
We process custom quote requests every day from contractors, equipment dealers, and fleet maintenance operations across the country. Our workflow is built around fast response, accurate model matching, and transparent pricing - not upselling.
When you can't find your part in our online catalog - because the model is discontinued, the part number is ambiguous, or you need a quantity not shown - you can request a custom quote. Our team will identify the correct part, confirm availability, and respond with pricing, typically the same business day.
Our process:
- Browse by brand and model number in our online catalog - or call 833-403-1010 for guided assistance
- Add to cart and check out, or submit a quote request for custom quantities or hard-to-find parts
- Orders ship free. Most in-stock items ship within 1–2 business days
Who We Serve
Our customers include demolition contractors, civil and utility construction companies, quarrying operations, concrete cutting specialists, equipment rental companies, and heavy equipment dealers. What they share: they run hydraulic breakers regularly, they buy replacement parts on a recurring cycle, and they've learned that waiting weeks for OEM parts at OEM prices is an unnecessary cost.
If you run hydraulic hammers - or stock parts for those who do - Big Hammer Co is built for you.
