Chrysler Water Pump Chrome Supercool

The TUFF-STUFF Chrysler Water Pump Chrome Supercool (Part Number 1317NB) is a high-volume mechanical water pump engineered for Mopar B-series and RB-series big-block engines, including the legendary 426 Hemi. This chrome-finished iron pump combines traditional mechanical operation with increased flow capacity, making it a preferred choice for street performance, classic restoration, and competition builds where engine cooling reliability is non-negotiable.

The supercool design delivers elevated coolant circulation rates compared to factory-specification pumps, reducing engine operating temperature under sustained load. The high-volume capability is particularly valuable in modified engines where increased horsepower generates additional thermal stress. Chrome plating provides corrosion resistance and visual appeal while the cast-iron construction ensures durability and proven longevity in both street and track environments. At 6.08 lbs and compact dimensions (8.5 × 8.25 × 9 inches), this pump integrates directly into original Mopar engine compartments without modification.

This pump is built for Chrysler enthusiasts restoring or upgrading B-block and RB-block powered vehicles, including 383, 400, 440, and 426 Hemi applications. Whether you're tuning a classic muscle car for summer cruising, preparing a vintage Mopar for show, or developing an engine for drag racing, the Supercool addresses overheating issues common in modified powerplants. The mechanical belt-drive design ensures straightforward installation and maintenance—no electric complications or modern sensor dependencies.

TUFF-STUFF is recognized in the Mopar performance market for delivering OEM-quality replacements and performance upgrades that honor original engine specifications while providing measurable thermal improvements. This pump represents the brand's commitment to reliability in classic and high-output applications where cooling system failure risks engine damage.
