The Texas Speed H-Beam Rods are made using heat treated and stress relieved 4340 Steel and undergoes a very detailed machining process to ensure maximum strength and reliability.

Each TSP Rod are torqued and re-torqued during the machining process. During manufacture, our rods are initially torqued and rough honed. The bolts are removed, and the rod & cap are then separated allowing the release of residual stress. The rods are then reassembled and re-torqued for final honing. This assures that the rod will still be round when you install it in an engine. Our Super H-Beam rods are rated for upwards of 900 flywheel HP.

All TSP Rods include L19 Rod bolts for Maximum Clamping force.

Blocks utilizing piston oil squirters may require some clearancing.

Important Note !
- Ring Gaps, Piston to wall clearances and Bearing clearances have to be checked by the end user to avoid engine damage
