PINION ANGLE ADJUSTMENT FOR LOWERED VEHICLES
If you've lowered your car, adjusting the pinion angle is a must to keep everything running smoothly. Our Rear Upper Trailing Arms make this adjustment simple, thanks to an aluminum hex design that lets you adjust things right on the car. Getting the pinion angle right not only prevents unnecessary wear and tear on your drivetrain but also helps avoid issues like wheel hop. With everything properly aligned, your car will ride better and perform at its best.
 
REDUCE REAR SUSPENSION BIND
Our trailing arms are designed to cut down on suspension bind, which means your car’s rear suspension will move more freely. The result? A smoother ride and better traction, giving you more consistent performance every time you hit the road.
