You need this Ford Racing (FRPP) M-6529-A302 Rocker Shim Kit if you are running Pedestal Mount Rocker Arms on your 5.0L Mustang! While Mustang pedestal mount rocker arms are known for their easy bolt down & go installation, their main flaw is that there is no adjustability! Luckily Ford Racing offers this pedestal mount rocker arm shim kit to aid in achieving proper lifter preload.
The shim kit includes 16 0.030" shims & 16 0.060" shims to cover the proper setting of one rocker arm set. You can even stack the shims for more adjustability! it is recommended that if stacking shims only to stack a 0.030" & a 0.060" to achieve 0.090". If more adjustment is needed a different length pushrod should be sourced.
Was hoping my pedestal rocker arms would be a bolt on deal, but after reading instructions and finding my bolts had about 1.5-1.75 turns from zero lash to the torque spec, I knew I needed these shims. They fit great and LMR has the best price around.
Yes, I would recommend this item to a friend!

Had my heads milled and needed them to adjust lifter preload. Worked perfect.

This is by far the best experience I have ever had buying parts for my mustang. There is no other place for me, then LatemodelResto. I have bought multiple parts over multiple orders and have had nothing but a smile from ear to ear. Aaron Westerman was my contact person from LatemodelResto. I could not ask for a better customer service representative than him! He went above and beyond multiple times for me and made my experience with Latemodel the reason I keep coming back. LatemodelResto will continue being my #1 stop for my Mustang parts.
