Factory steel rear trailing arms flex, causing undesired suspension geometry changes under load. Metal fatigue combined with shock forces from a pothole or curb, have been shown in some cases to cause the arm to buckle, turning a pleasant drive into a visit by roadside assistance.
ECS Tuning's Performance Rear Trailing Arm Set is an upgrade that has been engineered to address these issues, while also being lighter and more attractive than the factory steel component. Subjected to thousands of hard testing miles and countless computer simulations, these arms are engineered to be the last rear trailing arms you'll ever need. An all-around stiffer design exhibiting virtually no flex means more confident handling with no unintended geometry changes (the same can't be said for the factory arms). Despite being lighter than the arms your car has now, these control arms offer greater strength, meaning even after years of abuse they will still provide peace of mind (which also can't be said for factory arms).
A perfect upgrade for your rear suspension.
- Constructed from solid 6061-T6 aluminum
- Anodized for corrosion resistance
- Increased strength versus the factory steel arm - this arm fears no pot holes
- 25% lighter (384 grams versus 517 grams each)
- Easy to install upgrade for the home mechanic - will not affect alignment settings
Whether it's the first suspension modification you make, or the last component you've been searching for, ECS Tuning offers the ultimate upgrade for factory rear trailing arms.
