Your cart is empty.WFO Concepts Steel Degree Shims are designed to correct pinion or caster angles. They are machined from mild steel then zinc plated to help fight off corrosion. These shims are designed to bolt into your leaf spring pack. Hole is drilled and countersunk to fit a 3/8 center pin but can easily be drilled larger if needed. Sold as a pair. Made in the USA! Shim Dimensions: 2 degree shim: length = 5", height (thick end) = 0.238", height (thin end) = 0.075" 4 degree shim: length = 5", height (thick end) = 0.485", height (thin end) = 0.135" 6 degree shim: length = 5", height (thick end) = 0.625", height (thin end) = 0.100" 8 degree shim: length = 5", height (thick end) = 0.750", height (thin end) = 0.050"

These are a must for Ford super duty owners with a thicker front leaf pack. A thicker leaf pack to compensate in order to level out the front end. Many other applications as well. On a 02 F350 with a level kit the castor gets all messed up making the steering wheel not returning to center. Some say use bushings in the upper ball joint. That can put the axle in a predicament. The true way to gain castor or a better pinion angle is with these shims. After install with the only miles driven is down to a alignment shop I had no changes to toe or camber only caster, Dah. Had a 3 1/2* positive caster. Stoked. Good material, good machining, LONGER CENTER PIN/BOLT NEEDED. These shims must be integrated into spring pack. That is very easy to do simply by C-clamping the pack together removing the centerpin/bolt. Thin edge of shim forward thick edge towards rear. If your willing to do this change for your vehicle then you likely know the steps of how to install. Different vehicles different direction of shim placement. Quality Part!

These seem to be of high quality. I had a broken aluminum in a lift leaf pack and this matched the 4* tapered shim already installed.

Way better than any shim I’ve used.

I made my super duty into a single cab short bed. It has a very short and steep driveline angle. Used the 4 degree shim to fix the pinion angle.Had to drill out the center hole to 1/2†but I’d actually prefer to do so as there is no slop this way and it gives you an option to use a smaller center pin should you have one.So far so good

Slight modification required, but good quality. Pricey, but what made in USA isn't.
