Product Details

The COMP Cams 8659-1 is a precision-engineered dual taper pushrod designed for high-performance engine builds requiring exact valve train geometry. This pushrod measures 8.050 inches in length with a 7/16-inch diameter and features a robust .165-inch wall thickness for maximum strength and minimal deflection under high-load conditions.

Key Features:

  • Dual taper design optimizes weight reduction while maintaining structural rigidity
  • 7/16-inch diameter provides excellent strength-to-weight ratio
  • .165-inch wall thickness ensures durability under high-RPM and high-lift cam applications
  • 8.050-inch length precisely engineered for specific rocker arm and lifter configurations
  • Manufactured from high-quality chromoly steel with heat-treated construction
  • CNC-machined ends ensure proper seating and valve train geometry

This pushrod is ideal for racers and performance enthusiasts building engines with aftermarket cylinder heads, rocker arms, or camshafts that require non-standard pushrod lengths. The dual taper design reduces reciprocating mass while the thick wall construction prevents flexing that can cause valve train instability and power loss at high engine speeds.

thanks

Very easy and smooth, great experience.

Had to call customer service because I couldn't get paypal to work. He was very helpful and friendly.

good

Easy and quick check out

Picture was different then real product had to call to confirm fitment and was giving good answers.

Thanks for having what I needed in one stop.

By far the cheapest set of headers & x-pipe for my car on the market! They got them out the door first thing & sent me emails so I could track them. Very happy with this quality of service.

Great prices and fast delivery.
