Show original supplier description
The Smith Brothers trunnion upgrade kit provides a robust solution for LS and LT engines by replacing the standard trunnions. This kit utilizes micro-polished hardened shafts paired with C932 bearing bronze bushings for enhanced durability and performance. Unlike designs with small, loose parts, this kit eliminates potential hazards that could damage your engine. Integrated oil channels ensure continuous lubrication of the rocker arms, further contributing to the longevity and smooth operation of the valvetrain. The bushing trunnion style ensures a reliable and durable component for performance applications.

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.

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.
