To compliment the latest XE slipper piston, SBD have designed two new con-rods; one to suit the standard XE crank dimensions (26.35mm big end), which uses an L19 ARP bolt, the second version has a narrower big end (23.80mm) specifically designed for a narrow journal Steel crankshaft and supplied with 625+ ARP bolts.
SBD have managed to increase the overall rod length to 149mm due to the new smaller pin size of 18mm, this allows the pin centreline to be moved closer to the crown due to its smaller diameter.
At the same time they have also reduced the overall deck height to allow the standard block face to be machined to ensure perfect accuracy across the top of the block.
The rod also incorporates the latest designs for improved strength yet is still lighter than the original design.
This design of rod has several improvements which benefit the engine. There are two vertical grooves on the side of the rod, this directs the oil spray as it exits the big end vertically upwards towards the pin and the crown of the piston,. This has two benefits, it helps to supply lubricant directly to the gudgeon pin also the cool jet of oil to the underside of the crown of the piston helps to reduce the temperature of the piston itself. On the small end, we have repositioned the oil hole which feeds the small end bush. This is because the one at the top which is normally used effectively weakens the rod itself which increases the possibility of breakage when the rod is brought down by the crankshaft. By moving the oil hole to the side of the rod, there is far more material in this area to help maintain its strength.
Because of the above modifications it is no longer necessary to supply an oil feed through the bearing, even if your bearing still has a hole for the oil jet, it does not reduce its performance as the hole is simply filled with oil and the pressure in this area is maintained.
Rod weights are;
510g for the standard width big end rod.
490g for the 23.80mm narrow rod.
