Center Section 6-Bolt Cover Perm Mold Therm

The Center Section 6-Bolt Cover Perm Mold Therm from Winters is a purpose-built differential cover engineered for high-performance and heavy-duty automotive applications. This component protects the critical center section of your differential while managing heat dissipation through its thermally designed construction. Whether you're running a dedicated track vehicle, towing rig, or street machine with serious power output, this cover safeguards your differential internals from contamination and thermal stress.

The permanent mold thermic design combines structural integrity with advanced heat management—critical when differential temperatures climb under sustained load or aggressive driving. The 6-bolt pattern provides robust fastening that maintains a secure seal without compromising serviceability when you need to access the differential for maintenance or upgrades. Winters' manufacturing expertise ensures precise fitment and consistent quality across multiple vehicle platforms. The cover weighs 19.45 lbs and measures 14 x 8.5 x 24 inches, making it compact enough for most applications while maintaining the mass necessary for durability and thermal effectiveness.

This cover is ideal for owners upgrading to high-performance differentials or those running modified powertrains where factory cooling is insufficient. Installation requires removing the stock cover and securing the Winters unit with the 6-bolt configuration—a straightforward swap on most platforms. Verify fitment with your specific differential model before ordering, as center section covers vary by gear type and ratio. Mechanics and enthusiasts commonly specify this component when building tracked vehicles, drag cars, or street rods where differential longevity directly impacts reliability and performance.
