Check out Mustang 360's review and install our billet aluminum rear shock mounts for the S550.

Once the aftermarket shocks started coming out for the S550 Mustang, people all across the country ran into issues breaking the factory rear shock mount. Whether it was drag racing or road racing with very stiff shocks, customers were having all sorts of issues. That's when the team at Steeda got together to come up with a solution.

Made from billet 6061 aluminum, these mounts are designed to replace the weak cast factory units. Unlike the factory mounts that have a rubber bushing that binds and will deteriorate over time on lowered cars or cars with aggressive shock settings, these units feature a Steeda spec stainless steel spherical Teflon lined bearing for optimum performance and control. Unlike other aftermarket mounts, these mounts are compatible with adjustable shocks that utilize a top mounted adjuster.Steeda also designed this kit to provide 1/4" more clearance for wide rear tires!A great way to keep the bearings protected from the elements is to add-on the Steeda Rear Shock Mount Covers .

Steeda also went a step further by making five kits (Please review for fitment):
  • 555-8151 : All Stock Shocks, Viking Shocks, Ford Racing Shocks (10mm-1.5 diameter)
  • 555-8152 : Steeda Adjustable Pro-Action Shocks, Koni Adjustable Shocks (12mm-1.25 diameter)
  • 555-8160 : Steeda Non-Adjustable Pro-Action Shocks, Koni Non-Adjustable Shocks, KW V3 Adjustable Shocks (10mm-1.0 diameter)

If you are running stock shocks now but might upgrade to Pro-Actions in the future, no problem, there is no drilling required like the OEM mounts, these mounts are upgradable with a simple spacer and nut change ( 555-8153 ). The Steeda Billet Shock Mounts are a great upgrade to drag racers and road racers alike, or if you're running aggressive shocks on your car, these will greatly help with control with uncompromised durability.

Note: This rear shock mount DOES NOT fit the Magneride applications.

Amazing Quality and fitment, Steeda came through for me again! Fits RTR shocks!
Over the course of my s550 build I've hit a bunch of modding walls due to having a lowered ride height. Each time I was able to find a steeda product that solved my issues and improved the handling and feel of the car. Recently I purchased RTR ADJ shocks/struts at a low introductory price of approx $400. Unfortunately when I attempted 1st install, the rear shocks were missing strut top nuts and the new shaft diameter was larger than stock(12mm like Koni Yellows) and required drilling. I informed the other vendor of this but they were no help. I ended up going to the hardware store to determine the thread size and immediately looked to Steeda for a bolt on solution and these mounts fit the bill. Install was a breeze and was easily done in an hour with hand tools and a floor jack. The Steeda rear mounts have a nice solid feel to them despite being surprisingly light. After driving on them for the past few days these mounts w/ the upgraded shocks, its clear that the rear end float and bouncy feeling I used to get with the stock PP shocks is gone. Just for a bit of perspective, I also have the Steeda Ultimate stop the hop package, adj bump stops, adj rear camber arms, installed a year prior to this upgrade.
