034Motorsport Density Line Non-Adjustable Front Control Arm Kit for Audi Q5, SQ5, Q5 Sportback & SQ5 Sportback (2018–2024)

Fluid-free bushings that cannot leak set this 034Motorsport Density Line Control Arm Kit apart: it replaces all eight front upper and lower control arms on the Audi Q5, SQ5, Q5 Sportback, and SQ5 Sportback with arms using 70 durometer rubber bushings. The factory front arms can start wearing out as early as 40,000 miles, especially when the car is driven hard. As the bushings degrade and the ball joints develop play, alignment suffers and steering loses precision. The Density Line arms are engineered to limit unwanted deflection, and 034Motorsport rates them for tighter handling and more precise steering response than new factory arms. The factory arms use fluid-filled bushings. The Density Line bushings contain no fluid, so leakage is not a failure point.

This control arm kit carries a 24-month warranty.

This is the non-adjustable version of the kit. The upper arms hold fixed geometry, matching the factory layout. The kit covers every arm at the front axle and corresponds to these Audi numbers: upper front 4M0 407 505 B (left) and 4M0 407 506 B (right), upper rear 4M0 407 509 B and 4M0 407 510 B, lower front 80A 407 151 B and 80A 407 152 B, lower rear 80A 407 693 E and 80A 407 694 E, and front ball joints 80A 407 689 B. Rubber dust boots for the spherical bearings come in the box with the installation hardware. Each front corner of the Q5 locates its knuckle with two upper and two lower links, so worn bushings at any one pivot affect how the whole corner tracks. 034Motorsport designs, tests, and builds its Audi and Volkswagen parts in-house at its Fremont, California, facility.

Installation & Tuning Notes

034Motorsport says the suspension must be compressed to static ride height before any pivot bushing is tightened, which follows the factory procedure. Tightening the bushings with the suspension hanging puts far more twist on them than intended, and they will tear early. 034Motorsport's limited warranty on Density Line parts does not cover premature failure caused by improper installation, and the company strongly recommends professional installation.

Common Questions

Can I adjust camber with this kit?
No. This is the non-adjustable Density Line version, so the upper arms keep fixed geometry.

Does this replace all eight front arms?
Yes. The kit includes both front and rear lower arms and both front and rear upper arms for each side, along with ball joints and hardware.

PMB sells the complete Q5 front arm set so the axle can be done in one visit.
