M57 1000HP Billet 4140 Connecting Rods

We keep these on the shelf and DO NOT MAKE TO ORDER with long lead times like most other BMW diesel rods.  If we show stock, we actually have them and do not sell items not on the shelf.

These billet 4140 steel connecting rods are an exact replacement for stock M57 connecting rods with factory pistons and were designed to be used in applications up to 1000HP.

The bolts included 200,000psi and torque specs are 0055-.006" stretch or 55lbft with ARP lube if a stretch gauge is not available. 

Weigh matched to +/- 1 gram per set total and end weights.
