THE STRONGBOX IS BACK!

- UPGRADED, MORE AGGRESSIVE, READY TO ATTACK -

OUR CORE DESIGN VALUES

- ENSURE PROFESSIONAL GRADE PERFORMANCE -

We use only highly durable, performance grade components, and adaptive design to create an  unbeatably reliable underdrive that you can count on to get you where you need to be.

- BECAUSE QUALITY AND PERFORMANCE MATTER -

The Strongbox shaft is made from exceptionally hard 4340 alloy steel that is heat treated to provide incredible strength.  Throw anything you can at this shaft – you’ll break before it does…

- TESTED AND PROVEN IN THE FIELD -

WHAT'S IN THE BOX?

- HIGH PERFORMANCE, NO COMPROMISES -

We designed our Strongbox to be a DIY builder kit, meaning this case will ship empty and the customer provides the gears of their choice and does assembly and install.

The DIY Behemoth Strongbox Includes:

  • Front & Rear Billet 6061-T6 Housings
  • Integrated Clocking Ring on Standard (not Shortly) models
  • 4340 Alloy Heat Treated and Hardened  Shaft
  • Installation Hardware Pack
