Product Details

The Supertech Performance SEAT-H1003-R18 is a precision-engineered valve spring seat locator designed for Honda R18 SOHC i-VTEC engines. This critical valve train component ensures proper valve spring alignment and stability, which is essential for optimal valve train operation and longevity in high-performance and racing applications.

Key Features:

  • Precision-machined for exact fitment with H1003 series valve springs
  • Ensures proper valve spring alignment and seating pressure distribution
  • Compatible with Honda Civic R18 SOHC i-VTEC engines (2006-2011)
  • Designed for use with Supertech SPR-H1003S-R18 valve springs and RET-H1003-T1-R18 titanium retainers
  • Essential component for complete valve train upgrades and rebuilds

Spring seat locators are a crucial yet often overlooked component in valve train assemblies. They provide a stable, precisely positioned base for valve springs to seat against, preventing spring migration and ensuring consistent valve operation throughout the RPM range. When performing a valve train upgrade or head rebuild, replacing spring seats with precision components like the SEAT-H1003-R18 helps maximize the performance benefits of upgraded springs and retainers while ensuring proper valve train geometry.

Ok thanks sounds good

Great

Timely order. My only issue was that I was unaware that my item had already been shipped because the status of my order just said 'completed'. In reality, it was already shipped and halfway across the country! I was pleasantly surprised and surprisingly uninformed. Off my soapbox. Thanks!

I had no problem looking up and finding the item,and it only took about five minutes for me to order.Thank you for such a quick service.

Satisfied!

Like to see items instock and with fair pricing. I also do not like ot pay freight.
