- A throttle-stop (as best I understand) is a widget that connects to your throttle linkage such that it limits the amount of throttle opened initially on launch. It releases and allows full throttle upon reaching a predetermined time or RPM.

- A two-step shifter is a deal where one gets an automatic trans floor shifter such as the Cheeta (sp?) manual. It can be had with provisions and bracketry that allows connection to single or dual electric or compressed C02 solenoid(s). Said solenoid(s) provide the gearshift function again based on time or RPM.

They pretty-much allow full adjustability in throttle and gearing to help control power applied to the wheels on launch and accelleration.

 

I rarely take mine that high, but it doesn't feel too bad. Mostly feel my square tires. Haven't ever tried 4wd above about 30mph.

 

I've driven mine a hundred or so miles a few times with it in 4x4 going 80 mph plus. I think as long as the u-joints are in good shape it should do it pretty smoothly.
I usually run about 20 -25 psi less air in the rear tires than the front to try and keep them the same circumference.

 

That is true.........threse a lot more weight setting on them there front tire, quishing then down , then, on the rear.
