Delphi Suspension Trailing Arm P/N:TC3806

$48.99

Description

Keep the rear suspension located and controlled with the Delphi Suspension Trailing Arm TC3806, a direct-fit replacement for the 2005-2006 Nissan X-Trail. This rear trailing arm helps locate the wheel and control fore-and-aft movement, drawing on Delphi's OE steering-and-suspension expertise applied to their aftermarket portfolio.

Tested to the extreme: validated for OE-level performance below -40°C and above 120°C, with 720 hours of salt-spray exposure; extensive dimensional and material analysis targets close OE-to-aftermarket compatibility.
100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
Robot-welded: welding is automated for consistent quality and performance.
Precision ball studs: studs are machined to micron tolerances for durable, smooth joint operation.
Anti-corrosion protection: applied to each part for corrosion prevention and improved appearance.

Signs the original rear trailing arm may need replacing include clunks on acceleration, deceleration or over bumps, imprecise rear-wheel tracking, or a cracked, corroded or damaged arm. If a worn trailing arm is the cause, this replaces it. Sold individually.
