Connecting rods X-Beam Super Race - H beam - 5.5 - Chromoly - T1
Brand : CB Performance
Reference : SP-112432
The 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.
Short 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.
