LS Next Alum Block Parts Kit

The LS Next Alum Block Parts Kit by DART is engineered for serious LS platform builders and performance enthusiasts who demand precision-machined components for custom engine assembly. This dedicated kit addresses the core fastener and accessory needs of next-generation LS engine blocks, streamlining the build process for street machines, race applications, and high-horsepower street/strip hybrids. Whether you're assembling a budget-conscious 5.3L stroker or constructing a competition-grade 427 platform, this parts kit eliminates the frustration of sourcing critical hardware individually.

Manufactured from aircraft-grade aluminum, the LS Next Alum Block Parts Kit delivers weight savings without compromising structural integrity—a critical advantage in applications where every pound counts. DART's design focuses on OEM-compatible geometry and tolerances, ensuring seamless fitment with factory and aftermarket LS components including fuel rails, accessory brackets, and intake manifold systems. The compact 3.7 x 3.45 x 18.3-inch footprint houses precisely engineered parts optimized for thermal conductivity and corrosion resistance, with anodized or passivated finishes protecting against the harsh under-hood environment typical of boost systems and extended high-RPM duty.

This kit is ideal for engine builders, fabricators, and LS swappers tackling everything from first-generation LS1/LS6 refreshes to modern Gen IV and Gen V platform modifications. Professional shops and weekend warriors alike benefit from the standardized hardware specifications, reducing assembly downtime and minimizing the risk of mismatched fasteners or missing components. Weighing just 0.88 lbs, the kit's lightweight design makes it suitable for high-revving naturally aspirated engines as well as turbocharged and supercharged builds where inertia reduction directly impacts acceleration response and fuel economy.
