Pinion angle correction with drop blocks/bags - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**mfm3** · 05-11-2018, 06:26 PM

Did a search but did not find any info on this specific topic.

I have 2" drop blocks and bags in the back for approx 7" of total drop. Need to correct my pinion angle about 5 degrees. Does anyone know of drop blocks that also correct the pinion angle? If not, I have an extra set of 2" aluminum blocks that I will have machined to provide 5 degrees of correction.

The picture shows the outline of the 2" block. The red area shows an example of how machining an angle on the top side of the block could double a pinion angle corrector. Other ideas are appreciated.

I machined 2 1/2 degrees off the top of mine worked perfect.

Thanks...CPP's only option is 4 degrees which is probably good for most situations. $80
