12-TOOTH 4130 STEEL ARMATURE PLATE –

Our plates are cut from cold rolled steel which increases strain hardening by more than 20% and if that wasn’t enough, we added more than 50% extra material in critical weak spots that drastically reduce the strain on the armature plates engagement tabs.

Speaking of engagement tabs, our engagement tabs are machined into the armature plates unlike the factory tabs that are bent into shape.

Our machining process ensures no weak spots are created from a bending process.

At more than twice the strength of a factory armature plate, these are the most Extreme Duty Armature Plates available, PERIOD!

Torsion Spring Retainer –

All Billet Torsion Retainer

The OEM plastic component has been overstressed causing failures.

Sandcraft has completely redesigned and doubled the engagement surface areas.

It now is Billet aluminum, with internal and external engagement properties that raises the bar in durability and dynamic loads.
