Construction & Design:

This engine block is crafted from high-quality cast iron, chosen for its excellent wear resistance and thermal stability under extreme operating conditions. The block’s design adheres strictly to OEM specifications, ensuring seamless integration with existing components and accessories. The inclusion of billet steel main caps enhances structural rigidity, reducing flex and improving crankshaft support during high RPM or high load scenarios.

Finished cylinder bores and line honing guarantee precise cylinder alignment and optimal piston fitment, which are critical for maintaining compression and minimizing wear. The one-piece rear main seal design helps prevent oil leaks, contributing to a cleaner and more reliable engine operation.

It is sold individually and does not include main bearings or cam bearings, so these components must be sourced separately.

Professional installation is recommended to ensure proper torque specifications and alignment, especially given the precision line honing and installed studs and caps. Always verify fitment with your specific vehicle model and engine variant before purchase.
