Some of the features include:

 

  • Laser cut from .125” mild steel and features .250 Chrome Moly adjustment brackets.

  • Completely tig welded in a jig/fixture to assure quality and fit.

  • 9 available ½” adjustment holes to fine tune your instant center.

  • The center hole is in the stock location for class rules that require stock mounting points.

  •  Exclusive open design adjustment brackets allow easy Instant Center adjustments and set-up.

  •  Laser cut adjustment holes for precise tolerance.

  • Included hardware: ½” grade 8 bolts with AN washers and lock nuts, plus 3/4" DOM bolt sleeve and rod end spacers.

  • Custom offset control arm/rod end spacers available upon request at no additional charge.

  • 3/4" DOM sleeve steps up the 1/2" bolt diameter to 3/4", making it much stronger then 5/8" bolts and hardware.

  • Our exclusive design works with both mini tubbed cars and with stock wheel tubs. It does not intrude into the wheel tub area like some designs.

  • Lower edge of box wraps around the frame rail to promote additional strength and ease of installation alignment.

  • Reduced cross section width for lighter weight while maintaining superior strength.

  • Boxes have 1/8 thick welding ledge around perimeter to make it easier to weld to the stock sheet metal areas of the car such as the OEM floor and rocker panel.

  • Inner frame rail side gusset to allow easier access to bolt for adjustment.

  • Boxes are constructed for ease of installation and alignment. In most cars they slide right in place with no modifications after removal of OEM torque boxes unless the car has been damaged is this area.

  • Adjustment holes will work with a wide selection of ride heights.

  • They are only intended for use with lower control arms that have a ¾” rod end on the box end, or on both ends. They will not work on control arms that are solid mount in the front, IE poly bushing type.

  • Welding required
