All upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end to eliminate bushing bind, allowing the suspension to move smoother for better control. This keeps the tires planted firmly on the ground for improved traction and a more predictable, better handling car. For a long-lasting finish, tubular and boxed trailing arms are powder-coated gloss black, while the adjustable arms are zinc plated and anodized. Boxed Trailing Arms are constructed from 0.120'' wall cold rolled steel tubing for maximum strength and flex elimination. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings.

Manufacturer's Warranty — QA1

Manufacturer's Warranty — QA1
QA1 warrants this product to the original purchaser to be free from defects in material and workmanship for one year from the date of sale. A separate limited lifetime warranty covers only QA1's select shock and strut lines (Stocker Star, Proma Star, Ultra Ride and Aluma Matic) and requires registration at QA1.net/Warranty within 30 days of purchase. QA1 makes no other warranty, express or implied. Coverage does not apply where the defect results from improper or abnormal use, negligence, vehicle accident, incorrect installation or maintenance, or where the product has been repaired or altered in any way. QA1's liability is limited to repair or replacement of the defective product at its option; consequential and incidental damages are excluded. A claim needs an RMA number issued by QA1 — tag each item with the part number and a description of the defect — and the customer pays shipping to QA1 for inspection.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by QA1. Contact us if you need help with a warranty claim.
