Video: Engine Pro’s High Performance Nitro Black R Series Pushrods

With the increased performance capabilities of modern racing engines, making sure you have quality parts is important. Having a solid valvetrain plays a key role in keeping a motor running at its best, and good pushrods are the backbone in that system. The top-tier pushrods from Engine Pro fall under the Nitro Black R Series. These parts are what you want if big and reliable power are on the agenda for your engine.

The more rigid and stronger a pushrod is, the better it will hold up to the abuse a race engine can deliver. The Nitro Black R Series use 4130 chrome moly tubing as their base to give them a one-piece design and this makes them exceptionally stout. These pushrods receive a carbon nitride treatment that bumps their Rockwell “C” scale hardness to the 60-62 level.

The 5116 Series Nitro Black R pushrods are 5/16-inch in diameter. A thicker wall allows for these pushrods to be very strong in situations where there isn’t enough clearance for a bigger diameter unit. On the rocker arm end a .210 radius ball was used to allow bigger lift cam applications additional clearance to avoid interference issues. The pushrods in this series use .116-inch sized wall chrome moly tubing and are available from 6.000 to 10.000 lengths.

The 3121S and 3141S Nitro Black 1R Series pushrods are the 3/8-inch diameter offerings from Engine Pro. These pushrods use a .120 wall (3121S) and .140 wall (3141S) sized chrome moly tubing to give them the same strength as the 5116 series. A .210 radial ball end is also standard on the 3/8-inch pushrods to give the engine builder just as many options for rocker arms.
