Part #25350 is a pair of J&M Products adjustable rear upper shock mounts for S550 and S650 Mustangs. Forged 6061-T6511 aluminum with a spherical bearing in place of the factory rubber. Mil-spec anodized — select black or red on this page. Made in the USA.

Why the factory mount gives up

The stock rear upper mount is a cast body with a soft rubber bushing. Under load that rubber deflects, so the shock is working through a moving mount instead of a fixed point. With lowering springs or a stiffer shock that shows up as a bouncy rear and damping that never quite catches the axle.

These mounts replace that rubber with a spherical bearing so the shock can control the axle instead of the mount flexing.

What you get

• Direct connection. Spherical upper mount instead of a stock rubber bushing.
• Fits MagneRide and non-MagneRide. Same part for OEM and OEM-replacement shocks with 10 mm, 11 mm, or 12 mm threads.
• Height adjustable. Set rear shock position for lowered or performance ride height.
• Forged 6061-T6511 aluminum in place of the factory cast mount.
• Bearing: heat-treated 52100 steel ball, 4340 chrome-moly race, PTFE impregnated sintered bronze liner.
• Finish: mil-spec anodized, black or red.
• Sold as a pair. Direct bolt-on to the factory upper locations.

MagneRide

These mounts fit MagneRide cars. If you want to reuse the cap, drill the cap and install a grommet so the sensor wire still has a sealed path. The mounts work without the cap; the drill-and-grommet step is only if you keep the cap.

Öhlins

Do not use 25350 with Öhlins rear shocks. That application is part #25351.
