CB's X-Beam Super Race Rods are now available in five lengths to fit
more engine combinations than ever before. Our new X-Beam Super Race Rods are manufactured from 4340 Chromoly forgings,
then heat treated to Rockwell 34-38HRC, CNC machined, and stress relieved with a
micro shot-peen. Each X-Beam Super Race Rod is then visually inspected and magnufluxed.
The new X-Beam design has less windage than conventional rods, helping reduce internal engine case pressure.
The crankshaft end of the rod is torqued to 29 lbs., CNC machined, and precision honed to + or - .0002". The rod journal
bearing surfaces are hone finished to a fine crosshatch. Silicon bronze wrist
pin bushings are pressed-in and finish honed to + or - .0002". X-Beam Super Race Rods are available to fit VW and Chevy Rod
journals in lengths from 5.325" to 5.700". X-Beam Super Race Rods are assembled with ARP 2000 Rod Bolts and shipped in end-to-end balanced sets of four to
assure continuity and reliability.
X-Beam Super Race Rods are lighter and yet stronger than O.E.M VW
connecting rods. The rod caps are engineered to reduce the amount of internal
case clearancing required to drop in a stroker crank without giving up strength.
The X-Beam shape will shed oil instead of catching it, this helps
eliminate oil starvation at higher RPM’s. You can run strokes up to 76mm
without case clearancing. X-Beam Super Race Rods allow you to run longer strokes while
maintaining the structural integrity of the engine case.
rods, or long rods? The choice is yours, but modern engine builders know
that longer rods make more power by reducing side load on the pistons. Long
rods move the power band up the RPM scale because longer rods cause the piston
to "dwell" longer in the vicinity of top dead center. This produces a
cleaner burn of the air/fuel mixture, and there is actually a longer period of
time for the pressure created to press against the top of the piston. Rod
ratios are an important part of engine design. The key factor is that pure-bred
racing engines are equipped with the longest rods possible.
