Protect your Mopar LA small-block V8 from coolant leaks and freeze-related block damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set designed for Chrysler, Dodge, Jeep, and Plymouth 3.7L/225, 4.5L/273, 4.9L/301, 5.2L/318, 5.6L/340, and 5.9L/360 OHV engines (naturally aspirated applications; codes A273, A318, MD2, P31, R31, S31, T31, V27, V31, Magnum, Magnum HD; CNG, GAS, or LPG) from 1955–2003. This high-quality kit fits legendary models like Charger, Cherokee, CJ5/CJ7, Dakota, Dart, Durango, Grand Cherokee, Ram 1500/2500/3500, Valiant, Wrangler, and more – essential for engine rebuilds, refreshes, or replacing worn/corroded plugs in these versatile, torque-heavy small-blocks that powered muscle cars, trucks, Jeeps, and vans with unmatched reliability and performance. The kit provides all necessary premium brass freeze plugs (also known as core plugs or expansion plugs) to seal block and head casting holes, offering superior corrosion resistance over steel for dependable coolant containment and protection against cracking in cold climates or rugged conditions. Matched to the LA V8 specs, 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 vehicle's low-end torque, smooth operation, and trail-ready or work-ready reliability for years of on-road comfort or off-road adventure. This is not a universal kit for non-LA 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. LowPricedAutoParts is committed to providing the right parts with reliable customer support—message us your engine details or any fitment questions for fast, expert assistance. We're here to support your rebuild every step of the way. Shop with confidence knowing LowPricedAutoParts delivers quality automotive parts backed by outstanding service.
