Note: On 916-39521, the spring and frame bracket are Chrome, not Stainless steel.

 

Notes

We strongly reccommend the use of a front panhard bar (such as our 910-49801, at right) with four bar front suspensions. Four bar suspensions increase suspension travel over original wishbones or radius rods, which increases the need for side-to-side axle control. If using a Vega cross steering system, the panhard bar becomes mandatory as any side-to-side movement will cause bump steer.

Are 37-48 ford spindles the same as 28-48 ford spindles? I need to buy a new drop axle, and I'm not sure if my spindles will work. I have new 28-48 ford forged spindles.

Your aftermarket 28-48 spindles will work on the axle kit number 91639521 without any problems. The king pin diameter was the same from 28-48 but the spindles carry the 37-48 pattern and bolt spacing for the brake hardware.
