Description

The Real Street Performance Billet Main Caps are engineered to provide a robust upgrade for your Toyota 2JZ or 1JZ engine's bottom end. These billet main caps are manufactured to tighter tolerances than many aftermarket alternatives, ensuring a precise fit and optimal performance. They are specifically designed as a direct replacement for the factory main caps, facilitating a straightforward installation process for those rebuilding or enhancing their engine. The set includes the necessary components to replace the factory main caps on 2JZ-GE, 2JZ-GTE, and 1JZ-GTE engines. The use of billet steel construction helps to prevent flex and distortion that can occur with stock components, especially in modified engines pushing significant power levels. This upgrade is particularly beneficial for enthusiasts looking to build a high-performance engine that can withstand demanding use.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
