Product Details
This precision-matched kit, Assembled by ECS, integrates top-tier internals for a complete valvetrain and bottom-end overhaul. The Supertech performance valvetrain kit is a precision-matched set featuring dual springs, titanium retainers, and new spring seats developed for the performance enthusiast that wants the best the industry has to offer, built to keep the engine in one piece during high-horsepower operation.
To complete the cylinder head assembly, the kit features Supertech stainless steel intake valves and Inconel exhaust valves utilizing a factory-sized valve head diameter and factory triple-groove keeper setup. All Supertech stainless steel intake valves begin with a one-piece forging that undergoes a two-step forging process for excellent material grain flow, followed by CNC machining, nitride hardening treatment for final stress relieving, and a patented Superfinishing of the entire surface to ensure it is free of imperfections. The Inconel exhaust valves offer far superior reliability to OEM-style stainless sodium-filled exhaust valves which often crumble into the cylinder. This Inconel alloy material is a large upgrade over traditional stainless steel due to its extremely high heat resistance, and is highly recommended for engines that reach very high temperatures in turbocharged applications. This valvetrain layout is supported by included Integrated Engineering intake and exhaust valve stem seals.
For the bottom end, Mahle uses a proprietary tri-metal blend to provide a stiffer bearing under high load use, necessary for race engines. Each bearing is designed with state-of-the-art software for the ideal oil film thickness, which adds reliability and greatly reduces the chance of spinning a bearing. These bearings feature laser-marked identification marks instead of the more commonly seen stamped marks, allowing for better heat transfer from the bearing without disrupting the backing for more even wear. Sealing the top end is a premium Elring cylinder head gasket set, delivering complete sealing protection for the engine overhaul.
Key Features:
Inconel Exhaust Valves: Includes eight factory-sized, triple-groove Inconel alloy valves offering premium heat resistance over traditional stainless options.
Stainless Steel Intake Valves: Includes twelve factory-sized, one-piece forged intake valves subjected to nitride hardening treatment and patented Superfinishing.
Performance Valvetrain Kit: Supertech dual valve springs, lightweight titanium retainers, and matching spring seats designed for comprehensive valvetrain restoration.
Mahle Motorsport Main Bearings: Premium tri-metal blend set containing 10 half shells (5 with oiling grooves to be installed on the top side of the journal) featuring bearing locating tangs.
Laser-Marked Identification: Features laser-etched markings instead of stamped marks to maximize heat transfer and maintain an undisturbed shell backing.
Elring Cylinder Head Gasket Set: Comprehensive high-quality top-end gasket kit ensuring total fluid and compression sealing during reassembly.
