How thick is a 6 degree shim?

The steel degree shims are designed to change the pinion or caster angle on a leaf sprung vehicle. These shims are 2.5” wide, and work with 2.5” wide leaf spring packs.

Do I need leaf spring shims?

The rear depends on how it’s been set up. If it’s running a transfer case drop and a shim in the rear then you need the shim. If it’s running a SYE with cut and rotated spring perches then you shouldn’t need a shim.

How thick is a 4 degree axle shim?

Note:4 Degree – Shim thickness at tall end is . 551″ and . 191″ thick on the short end. Note: 2 Degree – Shim thickness at tall end is .

What are leaf spring shims for?

Steel shims to go between your leaf springs and your spring perch. These are used on leaf spring vehicles in order to adjust pinion angles and achieve proper drive line geometry.

How do you set pinion angle with leaf springs?

If you’re running a leaf-spring car, the pinion angle is set by the welded perches on the axle housing. The universal joint is the part of this equation that allows the pinion angle to change as needed. A universal joint is designed to be comfortable with between one and three degrees of pinion angle.

What is a good pinion angle?

According to Currie, the average car crafter should strive for between 1 and 3 degrees between the tailshaft of the transmission and driveshaft, and 1 to 3 degrees between the driveshaft and pinion. Furthermore, the two angles should be nearly equal (between 1 and 3 degrees), but always opposite (see crude diagram).

What are axle shims?

Axle shims are thin pieces of metal that are placed between an axle and a leaf spring to adjust the pinion angle of the vehicle’s axle. Typically, the pinion being set at a slight downward angle at the drive shaft yoke is best.

What kind of shims do I need for leaf springs?

Steel shims to go between your leaf springs and your spring perch. These are used on leaf spring vehicles in order to adjust pinion angles and achieve proper drive line geometry. Our shims are 2.5″ wide, machined from steel, and include a new set of 3/8″ diameter center bolts. Select size (in degrees).

How big is the suspension King leaf spring?

The Suspension King name is our guarantee of quality for leaf springs, spring hangers, spring shackles and bushings, leaf spring u-bolts and add-a-leafs spring kits and other replacement parts that you can rely on for consistent performance every time. Number of Leaves: 2 / 1 Measurement Size: 27-11/16 x 27-11/16 THIS LEAF SPRING ..

What should the angle be for leaf spring axle wedges?

The added stress of this setup could lead to your u-joints binding and your driveline components breaking. Installing a leaf spring axle shim changes the angle between your drive shaft and pinion yoke. Ideally, you should have a five- or seven-degree negative angle to ensure all components of your vehicle perform at their best.

How do you determine the right size Shim?

Use the calculator below to determine the right size shims. The shim calculator figures out the current joint angle, takes into account how much the drive shaft slope changes as a result of the shim, and aims to achieve a 2-3 degree net joint angle. The calculator is only for double cardan rear drive shafts.
