Ivey Technologies “One G” aka the Stage 2


SKU: 207

The “One G” (1100ftlb) is our most popular upgrade for the GTR. It is capable of handling 1500 wheel HP+ and over 1100 FTLB of wheel torque on our dynojet dyno. It has been used to go as quickly as 8.00 in the 1/4 mile, and over 178 mph.

The “Stage 1.5” is  limited by it’s reliability on highway pull type runs with over 900 ft lb, that being said it was a natural progression to add the Dodson Billet 2-6 gears to the very popular stage 1.5 setup and the “One G” was born, its the gearbox for the 8 sec racer on a budget who can’t spring for our stage 4+ and doesn’t need it due to lower power requirement. Can be also ordered with a 9 plate variant clutch with power holding over 1100 ftlb torque.

This Gearbox is easily upgraded to stage 4 and beyond if needed later on.
