034Motorsport Density Line Track Density Strut Mount for Audi A4, S4, A5, S5, RS5, Q5, and SQ5 (2008–2017)

Stiffer upper strut location for B8-platform Audis is the job of this 034Motorsport Track Density strut mount. It is molded from 85 durometer rubber for the A4, S4, A5, S5, RS5, Q5, and SQ5. A strut mount secures the top of the strut to the chassis and acts as the steering pivot on a MacPherson-type front end. The rubber in the mount can crack with mileage, and the strut bearing can wear, which lets the top of the strut move. Typical signs of a failing mount include clunks or knocks over bumps, extra vibration through the steering wheel, vague steering, uneven tire wear, and added body roll. The Track Density mount is about twice as stiff as stock, so it resists collapse and greatly reduces deflection.

034Motorsport parts sold by PMB Performance carry a 24-month warranty.

034Motorsport sells this mount for aggressive street or track use and considers it a must for lowered cars running higher than stock spring rates. It is a direct, drop-in replacement for the stock mount sold under OE numbers 8K0412377A, 8K0412377C, and 8K0412377E. The mount does not include hardware, so plan on reusing or sourcing the mounting nuts and bolts separately. 034Motorsport recommends replacing strut mounts whenever new strut assemblies go in. The mount is made in the United States.
