Quick Overview

The New Jeep JT is equipped with new computer controlled electro-hydraulic steering (EHPS), electronic stability control (ESC), electronic roll mitigation (ERM), and a weight saving aluminum housing steering gearbox.

PSC has taken the Jeep JT steering system back to the drawing board and engineered our exclusive Big Bore XD-JT Steering Gearbox and a traditional belt-driven High Flow Mechanical Power Steering Pump Conversion, producing an essential upgrade to solve the undesireable factory steering performance while able to efficiently handle the increased torque loads due to larger tire sizes and installing aftermarket axle assemblies.

Fits most Aftermarket Axles and Tie Rod Combos including:

Dana Ulitmate D44

Dana Ultimate D60

Dynatrac D44

Dynatrac D60

Teraflex D44

Positive caster increases align torque, aka the force that straightens the steering wheel when you go forward, which improves straight line stability of the car. Due to the geometry of positive caster this will also increase negative camber gain when turning, which will enable a wider tire contact patch. The caster angle is a major contributor to directional control. An insufficient amount of positive caster angle will decrease driver effort at the steering wheel, but may make the vehicle too sensitive and twitchy, especially as speed increases. To achieve the best on-the-road driving experience, recommended front axle caster setting is 7 degrees positive.
