Core Deposit Explained
Performance 4x4 operates on a core exchange system for our injector pumps.
If you require a pump to be sent out, please select the “core deposit” option. This includes a $600 refundable charge, which will be refunded once we receive your old injector pump.
Please note: your old pump must be complete and not disassembled to be eligible for the refund.
We work hard to keep turnaround times as fast as possible so you can get back on the road sooner.
- Send-in service: Typically completed within 5–8 days
- Core exchange option: If we have a pump ready to go, dispatch is often even faster
If a pre-built core isn’t currently available, lead times can extend up to 3 weeks, however, this isn’t always the case, so we recommend getting in touch for the most up-to-date availability.
