Reviewed in the United States on May 14, 2018

Size: 1.437" ODStyle: 0.060" ThickVerified Purchase

I admit, I grossly underestimated the shims required to install Comp 910 springs on my 7.3 Powerstroke. I had only purchased the 0.015 and 0.030 shims and discovered on the first exhaust valve that I would need a 0.060 + 0.015, with a 0.030 + 0.015 on the intake valve (this ended up being the closest match to the recommended spring seat height for nearly every pair of valves). For reference, I had 190,000 miles on the engine (and it had a rough previous life towing gooseneck trailers full time) and needed a couple new injectors, so this seemed like a good time to do it all at once (springs needed to swap all injectors for performance injectors). If you haven't already made my mistake, you can save money when you go ahead and buy the set of all three sizes of shim.
