Overview
The BD Diesel 1030606-DS-58 is a double stacked Xtruded transmission oil cooler paired with an electric fan. BD stacked two proven Xtruded cores to deliver over 40,000 BTU/HR of cooling.
The temperature drop is over 350% against the factory system and 136% better than the standard single core kit. The cooler is a universal fit, so mounting room and fittings decide suitability.
Key features
- Double stacked Xtruded cores
- Over 40,000 BTU/HR of cooling, per BD
- Electric fan type
- Universal fit per the manufacturer
Sizing a double stacked cooler
Stacking two cores increases the surface area available for heat exchange, which suits vehicles that work hard for long periods. The extra core also adds restriction to airflow, so the fan and mounting position need to draw enough air through both layers. Mount it where the core is not blocked by other hardware.
Think about the total package size before buying. A double stacked unit is larger than a single core, so measure the mounting area and clearance for the fan. Confirm the fittings suit your transmission lines, and plan the power feed for the fan before mounting.
- Measure both cores plus the fan before ordering
- Keep the stacked core clear of road debris
- Wire the fan with a fused, switched feed

Vehicle fitment
This cooler is a universal fit, so it is not tied to one vehicle. Check the cooler against your vehicle’s year, model and trim before buying.
Universal coolers still need mounting room and fittings that suit your transmission, and the space must accommodate both stacked cores. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check that the mounting area fits both stacked cores before choosing a location. The electric fan needs its own power feed, so wire it before the cooler is fitted.
What’s included
The cooler comes with its electric fan type. Plan for hoses, fittings and wiring separately.
