Push Rods, Uncut 3/8 Manton, .058 Thick

EMPI Uncut Manton 3/8 Chromoly Push Rods - .058 Wall Thickness

High-Performance Valvetrain Components

These Manton 4130 Chromoly push rods are engineered for high-horsepower Volkswagen aircooled engines. Measuring 11.50 inches in length with a robust 3/8-inch diameter and .058-inch wall thickness, these top-shelf components provide the rigidity needed to prevent flex under high-lift and high-RPM conditions. Sold as a set of 8, they are the ideal choice for builders seeking maximum valvetrain stability in modified engines.

VW Fitment and Applications

Designed specifically for performance-built VW Type 1, 2, and 3 engines, these push rods are compatible with modified Beetles, Karmann Ghias, Buses, and off-road Dune Buggies. Because they are uncut, they allow for precise custom sizing to achieve perfect rocker arm geometry in engines with non-standard deck heights, long-stroke crankshafts, or shaved cylinder heads.

Pro Tech Tips for Installation

Measure Twice, Cut Once: Since these push rods are supplied at a generic 11.50-inch length, you must use an adjustable push rod tool to determine the exact length required for your specific engine geometry. Ensure the rocker arm is centered on the valve stem at half-lift to maintain optimal performance and reduce guide wear.

Check Tube Clearance: When using 3/8-inch diameter push rods, always check for clearance against the push rod tubes. High-lift camshafts can cause thicker push rods to rub against the tube walls. You may need to use wide-mouth or offset push rod tubes to prevent friction and heat buildup.

Thorough Internal Cleaning: After cutting the tubes to your required length and before final assembly, you must thoroughly clean the inside of the chromoly tubes. Metal shavings or debris left inside the push rod can migrate into the oiling system and cause premature wear on lifters or bearings.
