24V Cummins Pushrods
With improved strength, performance and service life being our goals, we suggest upgrading pushrods to our Series 5 in all competition engines. If your engine is seeing an excessive amount of rpm, boost or nitrous, our Series 5 will provide an additional 105,000 p.s.i. tensile strength over our Series 3. The increase in rigidity will provide further accuracy of the valve timing and raise the point at which the valve train begins to surge. Our Series 5 pushrods are the strongest, most durable chromoly pushrods ever produced. This has been proven in our top fuel, blown alcohol, sprint car, cup, dirt short course, Baja, tractor pulling and offshore marine Champions, year after year.
Last but certainly not least, if you have made any changes to the engine requiring custom length pushrods, Manton sells pushrod length checking tools with proper ball and cup radius’ to replicate the OEM pushrod in both the 12V and 24V engine. Correct pushrod length will allow you to keep stock rocker geometry and therefore, allowing the scrubber cup of the rocker arm to correctly ride the contact area of the valve bridge in a 24v engine or the friction pad of the rocker arm to ride the valve tip in a 12V engine. If the adjusting screw is not at the stock position, it will change the ratio of the rocker arm, in turn affecting valve lift.
All in all, pushrods are a very important link in the valve train that are often overlooked at the expense of performance and service life.
