These highly anticipated LS ‘Xtreme’ rods are designed specifically for boosted applications who are looking to retain all the same proven premium forged 4340 material, ARP fasteners & quality workmanship that you would expect from a Callies product BUT with the addition of added strength of thickened flanges of the H-beams, Whilst a reduction in depth of cut towards the centre of the rod.

Callies have engineered these rods to remove the non-essential weight (taken from the beam) to help reduce & keep the overall weight of these rods in order.

These LS ‘Xtreme’ rods fill the void for those builds that are chasing a connecting rod that is STRONGER & capable of handling MORE HP than the standard Compstar rods.

The LS ‘Xtreme’ rods are designed for engines planning on seeing anywhere in between 1,200 to 1,800 horsepower mark.
