Show original supplier description
The JUN Auto Camshaft Kit is a Stage 1 performance upgrade designed for MITSUBISHI 4G63 engines featuring a lash type (HLA) valvetrain. This kit allows for a custom profile selection to suit your specific needs, offering enhanced performance over stock components. Included in the Stage 1 kit are high-lift camshafts and reinforced valve springs, which are a necessary component for achieving higher street specifications. For Lancer Evolution VII and VIII, an exchange to a JUN Ti Valve Retainer or CN9A/CP9A valve retainer is recommended when using JUN uprated valve springs. JUN Auto is a renowned Japanese tuning company with a long history in motorsport and performance engine development.

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.
