Product Details

The COMP Cams 4698-8 Valve Spring Seat Spacer Set is engineered specifically for Big Block Chevrolet applications requiring precise valve spring height adjustment. These precision-machined spacers allow you to optimize valve spring installed height when running higher-lift camshafts or aftermarket cylinder heads.

Specifications:

  • Outside Diameter (OD): 1.468 inches
  • Inside Diameter (ID): .630 inches
  • Thickness: .300 inches
  • Application: Big Block Chevrolet

Key Features:

  • Precision-machined for consistent valve spring height control
  • Allows proper valve spring seat geometry with high-performance camshafts
  • Helps maintain correct valve spring pressure and coil bind clearance
  • Essential for achieving optimal valvetrain performance
  • Direct fit for standard BBC valve spring pockets

Valve spring seat spacers are critical components when building or upgrading a Big Block Chevy engine with performance valvetrain components. By shimming the valve spring seat, you can achieve the proper installed height to ensure adequate coil bind clearance while maintaining the manufacturer's recommended spring pressure specifications.

Great Price!!<br>Fast Shipping!!<br>Would definitely use again....

quick

Great deals at unbeatable prices!

Piece of cake very thorough. Like the Amazon parallel site usage!

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
