Description
Product Overview
The COMP Cams Hi‑Tech Series pushrod is engineered for the most demanding high‑performance engines. Constructed from a single billet of chromemoly alloy steel with a precise 0.080″ wall thickness, each rod offers superior rigidity and resistance to bending under extreme combustion forces. A durable black‑oxide coating protects the steel from corrosion and wear, extending service life even in harsh racing environments. Sized Extra Large (XL) to accommodate larger valve train geometries, this pushrod fits a wide range of high‑performance cars, trucks, and motorcycles. The part number 7931-1 ensures a vehicle‑specific fit, and the alloy steel construction delivers a weight‑optimized balance between strength and inertia, crucial for maintaining valve timing accuracy at high RPMs.
Usage
Designed for both street‑driven performance vehicles and dedicated race applications, these pushrods excel wherever precise valve actuation is required. Install them in engines that have been upgraded with larger camshafts, high‑lift rocker arms, or aftermarket valve springs. The XL length is ideal for engines with increased deck height or custom valve train configurations, such as those found in drag racing, road‑racing, and off‑road trucks. Their robust construction tolerates the high loads generated by aggressive cam profiles, ensuring consistent lift and duration without deflection. Whether you are rebuilding a classic muscle car, tuning a modern sports sedan, or preparing a competition motorcycle, the COMP Cams pushrod provides the reliability needed for sustained high‑RPM operation.
Why Choose Us
COMP Cams has a legacy of over four decades in performance camshaft and valve train technology, and the Hi‑Tech Series pushrod reflects that expertise. Each rod undergoes a rigorous heat‑treatment process to achieve a uniform hardness profile, guaranteeing that the material will not soften under prolonged high‑temperature exposure. The black‑oxide finish is not only aesthetic; it acts as a barrier against moisture and chemicals, preventing rust that could compromise the rod’s structural integrity. Additionally, every pushrod is laser‑etched with the part number for easy identification during service. Our quality assurance includes dimensional inspection, hardness testing, and a fit‑check on the specified vehicle models, ensuring that you receive a component that meets OEM tolerances and performance expectations.

FAQ
What engines are compatible with the XL pushrod?
The XL pushrod fits a broad range of high‑performance engines, including V8, V6, and inline‑four configurations that have been upgraded with larger camshafts or custom rocker arms. Refer to the vehicle‑specific fit guide for exact model compatibility.
Do I need to replace guide plates when installing these pushrods?
No. The pushrods are heat‑treated and finished to work seamlessly with existing guide plates. However, for optimal performance, inspect guide plates for wear and replace them if necessary.
Can these pushrods be used in street‑legal applications?
Absolutely. While they are race‑ready, the pushrods meet all OEM specifications and are suitable for daily driving, providing the same reliability and durability as stock components.
How does the black‑oxide coating affect performance?
The coating does not alter the mechanical properties of the steel but adds a protective layer that resists rust and surface wear, extending the service interval and maintaining consistent performance.
Is any special tooling required for installation?
Standard pushrod installation tools are sufficient. Ensure proper torque on the rocker arm bolts and verify clearances with a dial indicator after installation.
