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.

Yes this kit includes the 91635006 batwings. The axle has a 2 1/4" spring perch boss.

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.

Ford Model T - 1934 Front Spring U-Bolt Kit, Stainless
(Part #91633024)
                        

Use with original or reproduction Model "T" thru '34 Ford front crossmembers. Includes two stainless steel U-bolts with nuts, one plain steel spacer plate and one plain steel lower bracket.

Note: Only the bolts are stainless, the clamping plate and leaf spacer are regular steel. Apply an anti-seize compound to ensure that the threads are not damaged upon assembly.

Weld-On U Bolt Plates
(Part #9161002)
                        

This kit will clean up the appearance of your front crossmember. It has two plates that weld to the crossmember, and another plate that holds the spring from the underside, eliminating the need to have the U-bolts come up over the top of the crossmember.
