Vorshlag Spherical Rear Shock Mounts for the SN95 Mustang
We make these spherical shock mounts to fit "pin" style upper shocks (not race-only "eye" conversion) for the rear of 1994-2004 "SN95" generation Mustangs. We will have a Fox Mustang version in another entry (the drilling template is the only difference).
We designed and built this production Vorshlag SN95 rear upper spherical shock mount set in June of 2025 and have had excellent results. We tested these with an MCS RR2 coilover rear shock, shown above.
Our first customer Chris beat on these shocks on track and autocross with zero issues, and along with the MCS damper and spring change, they helped drop his car's lap times at his home track by 3 seconds.
We realized long ago that a pin style upper has more total shock stroke than if we converted it to an "eye" style and used an adapter, so we make pin style spherical mounts whenever we can. These usually save as much as 2 inches of shock travel compared to eye mounts, and remove a big squishy rubber bushing that the stock style upper mount utilizes. This style mount also puts the top adjuster in a more accessible location. You don't have to remove the tire and dive under the wheel well to adjust the damper.
This is a revision of our C6Z06 front upper shock mount we introduced in 2024. The only tricky bit is opening up the shock tower hole to accommodate the spherical bearing holder, which sits above the shock tower but slides in from underneath, and held by a large threaded nut and snap ring from above.
We include both a 45mm annular cutter and a drilling guide to make this opening, which is pretty large. We like to throw a few extra stitch welds at the rear shock tower when doing this with coilover springs, to increase the overall strength.
Why not use an OEM rubber bushing? Well the factory rubber upper shock mounts for the SN95 chassis are just a big sloppy rubber sandwich bushing. Even when new, rubber shock bushings have to compress and will "slow down" damper reactions to vertical inputs in the suspension. We want the damper to react quickly, not slowly. Rubber also wears out over time, which can create a "thunk" noise. This is even more important once you switch to a coilover. The rubber mounts are not designed to hold spring forces and the weight of the car, and they quickly crush or split when tasked to support a coilover. Our spherical mounts are designed with that sort of use from the start.
Unlike most offerings we have found for the SN95 chassis, the Vorshlag system moves the bearing above the tower and allows for proper articulation and more total damper travel. A metal spherical bearing is also much stronger than rubber - and transfers more load to the chassis, so it becomes even more important to convert to spherical shock mounts when you add coilovers.
The SN95 rear shock mount system
We have made thousands of spherical shock mounts since 2008 for a variety of chassis. Our mounts feature a massive spherical bearing, and this version is made from Stainless Steel and is machined in-house here at Vorshlag on our CNC machines.
Some people are afraid to run spherical mounts on their street or dual purpose cars, mostly from a lack of knowledge. The important part of any spherical mount is that they are sized appropriately, that they fit the shaft they are attached to properly, and they allow "no bind" articulation at the rear shock mounting point.
The included drill guide is bolted into the chassis through the factory shock hole from underneath, tack welded in place, then used with the annular cutter to cut the 45mm ID hole off center from the stock shock hole. We need that extra offset to allow room for the massive spherical bearing holder and 19mm ID spherical. The drill guide then becomes a reinforcement that stays in the shock tower, to add some metal to this load path and take up space needed to make the threaded portion the right length and leave room for the large snap ring retainer.
Vorshlag Spherical Shock Mounts do a better job than rubber or poly mounts, and a lot better than a pin-to-eye adapter. The tolerances between the shaft and our spherical bearing are very tight - using custom machined bushings we tailor make for each configuration. Spherical shock mounts are all you see on a race car for good reason, but our design is also applicable to street use - for dual-purpose cars that see some autocross or track time.
Vorshlag shock Mounts use the largest spherical bearing on the market (19mm ID) - it is massive, which means it is strong. We use a U.S. made, Teflon lined, aircraft quality stainless spherical ball - stronger than the commercial grade import sphericals used in many competitors' shock mount designs. The spherical bearing location itself has been raised above the shock tower, to increase overall bump travel for your shocks. This is a huge advantage to the Vorshlag design, that other mounts just do not do.
We have tested this style of shock mount for 18+ years and they are silent, effective, and have no slop or bind in use. If you somehow manage wear out the massive spherical bearings in these shock mounts, we can rebuild them quickly and cost effectively here at Vorshlag.
UPPER STEM DIAMETER: These shock mounts are designed to work with virtually any rear shock that has a "pin" style upper shaft and that is made for the SN95 Mustang models listed. We use different upper and lower bushings (spool pieces) that we machine to adapt the big 19mm ID of our spherical bearing to the smaller shock shaft diameter of the very top of the rear shock. YOU have to tell us how to build your shock mount assembly by picking the proper upper stem diameter of your rear shocks at the drop down menu below. If in doubt, call us.
Virtually all shocks made for the SN95 chassis use a 14mm, 16mm or 22mm diameter main chrome shaft - we don't care about that part. The part we need to know from you is the very top - these can have a 10mm, 12mm or 14mm threaded upper shaft stem. Typically an OEM or non-adjustable shock has a 10mm upper stem but an adjustable aftermarket shock has a 12mm or 14mm upper shaft diameter (the Corvette shock below is just there to show the upper stem bit we care about).
The shock mount sits on bushings that fit a step where it goes from the big diameter and necks down to the small upper stem diameter. See these images for a better explanation. If you are unsure about shock shaft upper stem option to choose, please email or call us.
Shipping weight 3.0 pounds. Sold as one pair, for the rear upper shock location on an SN95 Mustang chassis only.
