As good as Ford made the BOSS 302 Mustang, there is still room for improvement to make your BOSS 302 even better than it already is with our handling packages.

Our Level 2 package includes our BOSS 302 specific springs, adjustable upper strut mounts, adjustable panhard bar, and adjustable front and rear swaybars.

The springs in this package greatly improve the BOSS 302's overall weight distribution. This is achieved by lowering the ride height only 0.2 inches in the front, but the rear comes down 0.7 to 0.8 inches.

With the front height remaining largely unchanged your front roll center geometry remains optimal. Spring rates are substantially increased to greatly reduce body roll and reduce nose dive under braking for greatly improved control and balance.

Thanks to our decades of engineering experience with Mustang springs, these springs achieve all of this while maintaining near stock ride quality characteristics, so if you enjoy taking your BOSS 302 Mustang around town, you will enjoy it even more with these springs!

The included adjustable strut mounts feature a +1/-1 degree range of camber adjustment. Manufactured from billet aluminum, billet steel, TIG-welded, nickel plated, and grade 12.9 hardware, the bearing chosen for our mounts is a fully caged 70mm diameter 7200lb capacity needle roller bearing for long life and incredible strength. Triple sealed to keep out dirt and water and isolated in a custom designed urethane bushing, our mounts provide no increase in NVH while maintaining near O.E. levels of impact harshness and comfort.

Our adjustable front swaybars feature 3 position of adjustment on both the front and rear bars for fine tuning of handling balance. At their stiffest positions the front swaybar has 27% more roll stiffness than stock and 83% in the rear.

Rounding our the package is our adjustable panhard bar which features 4130 chrome moly alloy steel construction, not just ordinary mild steel like the factory piece and other aftermarket offerings. Our chrome moly alloy construction makes it lighter than the factory bar by 4 pounds and lighter than any other aftermarket piece.

Our bar is length adjustable to adjust rear end offset to a more optimal position regardless of ride height and our urethane bushings reduce deflection under load for noticeably improved steering response and control.

Add up the parts in this package individually and you will see the great savings and value this package provides. Take your BOSS 302 Mustang to the next level of performance and enjoyment today!

Just Fantastic
This stage 2 handling pack is just fantastic, my Boss feels like it is on rails. get's into and out of corners better than ever before, it is a little stiffer but when you go with a stage 2 as this is it is going to be a little stiffer got used to it real quick.
