Product Details

The Prothane 7-517-BL is a black polyurethane manual transmission mount kit engineered as a high-performance upgrade over factory rubber mounts. Designed specifically for the Chevrolet Cobalt with 2.2L and 2.4L engines (2005–2007), this transmission mount kit delivers significantly improved drivetrain rigidity and torque control compared to soft OEM rubber components.

Factory rubber mounts are prone to deterioration over time, leading to drivetrain slop, excessive transmission movement, and ultimately, mount failure. Prothane's polyurethane construction resists oil, chemicals, and road contaminants that break down rubber, ensuring long-lasting performance under demanding conditions.

Key Features:

  • Manufactured from high-quality, specially formulated polyurethane — far more durable than OEM rubber
  • Features Prothane's poly-locked "run-safe" interlocking device to prevent complete mount failure and keep you moving even if the urethane is compromised
  • Engineered to control torque and reduce unwanted transmission movement for a tighter, more responsive drivetrain feel
  • Resistant to oil, chemicals, heat, and road contaminants that degrade rubber mounts
  • Application-specific design — not a universal fit — ensuring precise fitment and maximum performance benefit
  • Available in black (-BL suffix) or red
  • Designed for front or rear transmission mount position on the 2.2L/2.4L Cobalt platform

The Prothane 7-517-BL is an ideal upgrade for performance-minded drivers looking to tighten up drivetrain response and eliminate the slop associated with worn or soft OEM transmission mounts. Backed by Prothane's commitment to application-specific engineering, this kit installs using the existing mounting hardware and location.

These people are just awesome! I got my Thule Bike Rack for a fraction of the cost compared to everywhere else. Shipping was very fast and cheap but when I received it there were a couple of missing hardware parts. Thule wanted to make me ship the whole thing back. Rob Fratu of Autoplicity took control of the situation and got Thule to ship me the missing parts and some extras, all within a couple of days. I cant remember a better experience with a retailer.

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

They had what I needed, No hassle ordering. and it shipped fast.

very easy to make order

Good so far

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!

Great store! Best prices, fast fedex shipping. Very satisfied, will buy from Autoplicity again!
