In competition such as crossing and drag racing the revision of the engine is a returning event, where many components of the engine block are used for several times. This applies also on the H-beam connecting rods, like those we present under # 1602-15 -> 1602-23. The bolts for assembly of these rods are nevertheless less appropriate to be used again and we recommend to replace them upon each revision. We can offer these bolts in a good quality each from stock.
