LowPricedAutoParts Brass Freeze Plug Kit (Expansion/Core Plugs) - Fits Chrysler Dodge Plymouth 2.8L 170 3.2L 198 3.7L 225 Slant Six Engines 1960-1987

Protect your classic Mopar Slant Six from coolant leaks and freeze-related block damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set designed for Chrysler, Dodge, and Plymouth 2.8L/170 (1960-1971), 3.2L/198 (1970-1974), and 3.7L/225 (1960-1987) OHV inline-6 engines (naturally aspirated applications). This high-quality kit fits a wide range of iconic models including Valiant, Dart, Barracuda, Duster, Aspen, Volare, Belvedere, Fury, Charger, Coronet, Ramcharger, and various Dodge/Plymouth trucks and vans – a must-have for engine rebuilds, refreshes, or addressing corroded/worn plugs in these durable, torque-rich Slant Six powerplants that defined Mopar reliability for decades. The kit provides all necessary premium brass freeze plugs (also known as core plugs or expansion plugs) to seal the block's casting holes (typically 3–5 per side), offering superior corrosion resistance over steel for reliable coolant containment and protection against cracking in cold climates or harsh environments. Matched to the Slant Six's 3.400" bore specs and factory hole sizes, these plugs provide a precise, OEM-style fit that minimizes leak risks, maintains cooling efficiency, and promotes long-term engine health. Ideal for tackling age-related deterioration during overhauls – this set helps revive your Mopar's smooth, torquey performance and keeps it running strong for years of enjoyable cruising or utility work. This is not a universal kit for non-Slant Six engines or severely damaged blocks without inspection – professional measurement of plug holes, thorough cleaning, and correct installation techniques (with sealants as per Chrysler guidelines) are essential for a tight, distortion-free seal. Always verify hole diameters and drive plugs squarely during assembly. Verify your exact year and application before ordering.
