Product Details

The COMP Cams 4854-8 is a precision-engineered one-piece guide plate set designed specifically for GM LS engine applications using 5/16" pushrods and 8mm rocker studs. These flat-style guide plates provide critical pushrod alignment, ensuring optimal rocker arm geometry and valvetrain stability at high RPM.

Key Features:

  • One-piece flat design for GM LS engines with 5/16" diameter pushrods
  • Compatible with 8mm rocker arm studs for secure mounting
  • Precision-machined pushrod guide slots maintain proper alignment
  • Prevents pushrod deflection and lateral movement during operation
  • Manufactured from high-quality materials for durability and heat resistance
  • Sold as a set for complete engine installation

Guide plates are essential for maintaining correct pushrod-to-rocker arm alignment, reducing side loading on valve guides and extending valvetrain component life. This set is ideal for performance street engines, race applications, and engine rebuilds requiring precise valvetrain geometry.

Bought a Husky trunk liner for my Civic. Autoplicity had the lowest price I could find, plus I received it in two days. Only problem I had was that their website had a problem with the part fit check. Although the description and part number was for the 2012 Civic, the part check said it would not fit. Had to wait until Monday to call customer service to verify that it would fit before I ordered. Would definitely order from Autoplicity again.

Was a whole lot faster and easier than other websites. Also a whole lot cheaper!! Good job

Great company, professional handling and super fast shipping. Will buy from them again.

Ordering was easy. Hope the parts fit my car.

Easy to order
