86-97 Ranger / Explorer 4WD Dana 44 TTB Conversion Kit

Solving the Dana 35 Spindle Problem — Permanently The Dana 35 TTB spindle used in 1986-1997 4WD Ford Rangers and Explorers has three documented failure modes — all of them cracks that propagate from stress concentrations in the spindle casting. The Dana 35 spindle was adequate for factory use cases, but under the loads of long-travel suspension, wider track width, or aggressive off-road use, spindle failure is a matter of when, not if. The GIANT MotorSports Dana 44 TTB Conversion Kit eliminates all three Dana 35 failure points by replacing the entire beam and spindle with factory Dana 44 hardware — a proven upgrade the 4WD off-road community has relied on for decades.
