We make these shims from solid steel for maximum durability. Designed to handle the rigors of trail use, these shims actually become part of the spring pack. Many other shims on the market float between the spring pack and the spring perch reducing the engagement of the center pin. Our design will not come loose or fall out. Can be used front or rear to set pinion angles. 2.5" wide springs only.
We're working on getting more reviews for this product. In the meantime, here's what people are saying about 4WP

Q: I put a 4" trail master lift in my 93 YJ and the rear leaf shims are 2.5 degree shims from a pro comp kit, The trail master shims are listed as 2 degree my question is will that half of degree make a difference, I'm getting a small vibration @ 38 mph Answer this question
A: Mike- Thank for the question. The 2.5 degree shims can make a difference but i would replace / check your U joints and checked front tire balance and transmission mount before we changed the shims.

Q: Do I need to have a different center pin other than what's on my stock springset? Answer this question
A: Hello Diesel Dog, Thank you for the question. No, you can use the stock size center pin. We do recommend reviewing and replacing the center pins if needed.
