Q & A

What's in the Box

Achieve a smoother, more comfortable ride with one of Posies Super Slide™ springs! The ends of the spring leaves of a Super Slide™ spring have a unique "dimple" shape that retains a moly-nylon button which works as a dry lubricant to stop leaf-to-leaf interference. This freedom from friction lets the spring move more easily, thereby giving a softer, quieter ride.

  • 35-3/4" Reverse Eye
  • Made in the U.S.A. from high grade tempered steel
  • Reversed eyes for a 2" drop compared to stock
  • Get your ride lower without sacrificing ride comfort
  • Plain steel finish

If the perch boss center to center is 40.5 then the 35 ¾” spring would be within ¼” and would work fine with a little compression of the spring required for installation.

This spring 58020374L is intended for a spring in front of the axle with split wishbones. If putting the spring behind you will need a shorter spring as you will have the spring pivots and shackles inside the wishbones.

Our spring # 580-2100 spring is for the 48 ford with stock wishbones, stock crossmember and stock axle.If you have split your wishbones and kept the angle of spring perches ahead of the axle angled in the stock direction it should work.

How much will this spring lower the ride height compared to the stock spring on a 40 Ford PU?

Part number 58020374L, 2040, and 2100 The amount of height reduction is compared to a standard height new Ford spring and will not equate to an original spring that has settled and sagged over time. The 58020374L is a reversed eye relaxed spring lowering a total of 2” and for the 35-40 Fords. The 5802040 lowers the front 1” with the reverse eye springs and for the 37-41 Fords with stock wishbone. The 5802100 is a reverse eye relaxed spring that gives a total drop of 3” when compared to a new spring. Feel free to visit with a tech on options and applications.

Stainless Steel Spring Clamps, 2 Inch Wide Leaf Spring
(Part #91033202)
                        

Stainless steel spring clamps to keep your front or rear cross spring in alignment. Works with all brands of leaf springs.

To determine which spring clamp will fit your application, use a tape measure, ruler or caliper to measure the width of the main spring leaf (not length of leaf or leaf thickness) and order the spring clamps for that width. Some later fat-fendered Ford cars used the 2" wide springs in front.

  • Stainless steel
  • Hex head - 7/16" Wrench
  • 1/4"-10 thread pitch
  • Under-head bolt length - 2.70" long
  • Bolt hole diameter - 1/4"
