Product Details

Built to the demanding standards of bracket, drag, and oval track racing, these valves are the go-to choice for high-performance builds operating under 8,000 RPM. Each valve features the Bead Loc® groove, which requires Bead Loc® valve locks for proper retention — a critical consideration during assembly.

Key Features:

  • Head Diameter: 1.575 in. — exhaust valve sizing for the Chrysler HEMI 5.7L platform
  • Overall Length: 5.125 in.
  • Stainless Steel Construction: Exhaust valves manufactured from XH-426 high-grade stainless steel alloy for exceptional durability and heat resistance
  • Chrome Stems: Chrome-plated stems provide superior wear resistance and extended service life
  • Hard Tips: Fully hardened valve tips resist wear from rocker arm contact
  • Swirl Polished Underhead: Swirl-polished radius under the head optimizes flow characteristics and reduces hot-spot formation
  • Fully Machined Combustion Face: Precisely machined combustion face ensures proper sealing and combustion efficiency
  • Bead Loc® Keeper Groove: Required for use with Manley Bead Loc® valve locks (sold separately)
  • Race Master (Straight Stem) Design: Straight-stem profile suited for high-load racing applications

Manley Performance has been setting the standard in performance valvetrain components for decades. The 11697B-8 Race Master exhaust valves are recommended for alcohol-fueled engine applications and are compatible with the 2009–2024 HEMI 5.7L VVT cylinder heads. For proper installation, verify guide clearances to match Manley's exhaust stem specifications.

This site is awsome! excellent customer service, lowest rate, Fast shipping!<br><br>I will save this site for my bookmark! %100 must check auto store site.

Great price on name brand parts. Quick shipping. Will use again for my next order of parts.

I got a cargo box from autoplicity. As far as online purchases go to delivery, everything went perfectly. The only comment I have for Autoplicity would be to send out a confirmation email when the purchase is first made. The first communication wasn't until 3 days after I made the purchase.

Best price I could find for the brand new name brand product I ordered. Fast shipping as well.
