Eliminate pushrod flex, reduce valve-train harmonics and increase valve lift

Fixed Length 4130 Chrome moly one piece pushrods with swedged formed ends. Heavy duty 7/16 diameter tube with 0.165 wall thickness, precision concentricity, heat treated with a black oxide finish. Intake and Exhaust length pushrods are stock replacement lengths and designed to work with the factory base circle camshaft dimensions. These pushrods work with all Feuling, stock and SE Milwaukee Eight camshafts.

Note: If using a camshaft other than Feuling, Stock or SE, please contact your camshaft manufacture to verify if the base circle is stock sized or modified.

Due to the unstable nature of this 4 valve engine design with 1 rocker arm activating 2 valvesprings Feuling highly recommends running one piece pushrods over quick install adjustable rods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues.

Quick install pushrods are said to be easier to use, however they cannot compare to a solid pushrod for strength and durability

#4086 HP+ 0.165 Wall. -0.040 shorter for engines with decked cylinder heads and running thinner head gaskets. Note the factory head gasket is 0.050 thick and the SE and majority of aftermarket head gaskets are 0.040 thick, aftermarket 0.030 head gaskets are also available.


TECH TIP FOR USING 1 PIECE PUSHRODS:
1.) Remove gas tank, spark plug wires from plugs, left side spark plugs, fuel injector plug ins, compression release plug ins etc.
2.) Remove voltage regulator bracket bolts qty. 2
3.) Remove front top engine mount, from frame first then cylinder heads
4.) Remove exhaust
5.) Remove oil line, oil cooled models use a small catch tray on top of trans cover, wad of rags in the front to catch oil
6.) Remove cam cover, rotate engine to timing marks
7.) Remove top rocker covers, rocker arms, pushrods, pushrod tubes, lifter covers
