When it comes time to lift or modify your IFS Hilux the first sign of trouble is usually the alignment and handling of the front suspension. While minor adjustments can usually be done with the lower camber bolts, bigger lifts will need a lot more!
Another problem many find is that once a longer travel shock or a spring package that allows increased travel is fitted, the upper control arms may contact the chassis or the spring itself. A steeper angle on the upper control arm moves the steering knuckle inboard and increases the angularity on the ball joints, sometimes maxing out their movement.
With a raised suspension height, the OEM upper ball-joint is forced to operate at an extreme angle and wider tires may not clear the factory upper control arms. An over-stressed OEM ball-joint also has the potential to separate or break, leading to catastrophic failure of suspension, steering, and CV axle. The preferable solution is to replace the factory upper control arm with a newly designed arm, which allows greater clearance for the thicker or heavier aftermarket coils generally required to lift the vehicle.
The Carbon Send-IT Upper Control Arms feature quality ball joints and high-quality rubber bushings, they are designed to correct alignment angles while maintaining factory ride quality. the H/D steel design provide the strength and durability needed for the most demanding environments.
