Coolshirt Rally System Retrofit Kit
The Coolshirt Rally System Retrofit Kit upgrades older Coolshirt 2-person rally systems — manufactured prior to 2024 — to the current CPC American-made connector standard. It replaces 2 bulkheads, 6 hose connectors (4 female, 2 male), and 4 male garment connectors in one kit, covering both occupants' connection points. This lets you keep an existing Rally cooler in service while standardizing on parts and accessories that match Coolshirt's current connector lineup. A practical, cost-effective alternative to replacing an otherwise functional 2-person cooling unit.

The Coolshirt® Rally System Retrofit Kit is a connection conversion kit built for Coolshirt's 2-person rally cooling systems manufactured prior to 2024. If you're running an older Rally setup serving both driver and co-driver and finding it harder to source matching connectors, or you want your system to align with Coolshirt's current connector lineup for easier future part-sourcing, this kit handles the upgrade in one purchase.
The kit replaces the connection points throughout the system: 2 bulkheads (the fittings where hose meets the cooling unit), 6 hose connectors (4 female and 2 male — covering the Y-hose split to both occupants), and 4 male garment connectors (2 per occupant). All retired Coolshirt connectors are swapped for upgraded CPC American-made connectors — the same connector standard used across Coolshirt's current hose, garment, and cooler product lines.
This retrofit is a practical option for rally teams with an otherwise functional cooling unit who don't want to replace the whole system just to modernize the connectors. It also simplifies future maintenance for both occupants' gear, since replacement hoses, garments, and accessories purchased going forward will already match the upgraded fitting standard rather than requiring you to track down older, retired connector types.
