Trend’s line of Precision pushrods are machined to some of the most exacting tolerances in the industry at +/- .0005″. They are polished, cleaned, 100% individually inspected and packaged in individual sleeves with near-surgical exactness.
The Precision series is the upper echelon of pushrod design and manufacturing and favored by NASCAR cup teams turning nearly 10,000 rpm for hundreds of laps at a time. When it comes to durability and attention to detail, the Precision series is certainly a quality option.
These pushrods are created from 4130 chromoly thick-wall tubes, and are made to tight tolerances: ball end radius to plus or-minus .001″ in OD and length to plus-or-minus .005″. Every pushrod is checked to ensure accurate length and is cleaned with a special brush and solvent to ensure its internals are free of heat treat scale or other contaminants.
Trend’s Precision pushrods are available in lengths from 7.000″ to 11.5″ and in increments of .025″. Diameters include 7/16″ or 1/2″ or 9/16″ and with ball-ball ends or ball-cup ends in either 5/16″ or 3/8″. For more info: http://trendperform.com/
