Product Overview
Restore your Audi's legendary handling and ride quality with the iFJF 10-Piece Front Suspension Control Arm Kit — precision-engineered for 2011–2012 Audi A4, A5, S4, S5, and Q5 Quattro models. This complete kit replaces all eight front control arms (upper + lower, left + right) plus both stabilizer end links in a single package, saving you hundreds compared to buying individual arms from the dealer.
Each control arm is manufactured using advanced forging, casting, stamping, and robotic welding processes to ensure OEM-level fitment and durability. Pre-installed rubber bushings and ball joints mean no pressing required — bolt on and go.

Frequently Asked Questions
Q: Will this fit my 2011 Audi A4 without Quattro?
A: No, this kit is designed specifically for Quattro (AWD) models. FWD (front-wheel drive) models use different control arm geometry.
Q: Are the ball joints pre-greased?
A: Yes, all ball joints come pre-lubricated from the factory and are maintenance-free for their service life.
Q: What's the difference between the M14 and M12 versions?
A: The ball joint stud thread size. 17mm nut = M14 × 1.5 (this listing). 16mm nut = M12 × 1.5 (available in our other listing). Measure your existing ball joint nut before ordering.
Q: Do I need a wheel alignment after installing?
A: Absolutely. Any control arm replacement changes suspension geometry. A professional 4-wheel alignment is required immediately after installation.
Q: How long will these control arms last?
A: With normal driving conditions, expect 60,000–100,000 miles of service life.
