Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

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.

Product features:

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.

Torque for bolt is 74 FT LBS
