NexTek Valve Springs
Manley NexTek valve springs are simply "Better by Design" and our NEW Oval Track entry is no exception. Part Number 221445P is capable of handling upwards of .800" valve lift in the most rigorous applications. They come fully polished as a standard feature for enhanced surface finish and better fatigue life. These springs have already been tested and proven by some of the very best Dirt Late Model engine builders in the country. In fact, one of the top drivers in the series just reported "zero load loss" after 800 laps of racing during Florida speedweeks........click here for detailed specifications. |

TensileMax Steel Retainers
These are the ultimate retainers in the industry; for the serious engine builder who demands the very best. Extremely lightweight (within 2-4 grams of lightweight titanium versions) but able to withstand that dreaded "wear and tear" that commonly occurs from the valve spring, our TensileMax retainers are specially heat treated to provide a hardness of Rc 52-54. These retainers have been enormously successful and solved many engine builders' "wear" problems at tracks throughout the country. Available NOT ONLY for the above 221445P spring, but also for many of our other oval track part numbers.......click here for our full range of offerings and complete specifications. |

3/8" and 5/16" Diameter Larger .120" Wall Thickness Pro Series Pushrods
Manley pushrods, manufactured from 4130 chrome moly material, are a ONE PIECE "swedged end" design. The ends are meticulously formed with exact radii and the parts have tightly controlled concentricity. They are heat treated and black oxided for a hansome finish. We are proud to introduce larger .120" wall thickness pushrods to our vast, existing lineup of .080" wall thickness parts in BOTH 3/8" AND 5/16" diameters. The thicker wall increases the stiffness of the parts, providing better valvetrain stability in certain applications where needed.......click here for our complete listing of part numbers and lengths. |
