Guys,
I ordered the QA1 package from Dan Ruth. I noticed that the QA1s do not come with bump stops. Is the 0.875 long / 1.9 wide the correct one to order?

I use the same QA1 shock front & rear and installed the QA1 BC02 bump stops all around which works for my application (and matches your description): https://www.summitracing.com/parts/qa1-bc02
But the BC01 will give you a larger tuning window if you think you need that: https://www.summitracing.com/parts/qa1-bc01?rrec=true

Sean, I know nothing about Dan Ruth's coilover kit but can give you some tips on your front set-up. I run the double adjustable QA1 Proma Star #DD403 shock on all four corners (my rear suspension is my design) and on the front I run these inverted so the adjusters are easy to access. To run the shock inverted you have to run a shorter spring and use the QA1 extended spring caps https://www.summitracing.com/parts/qa1-9018-113
I also run 250 lb/in springs on the front as the stiff springs FFR supplied in the kit are more suited for a 1-ton truck. The 250 lb/in are a little too stiff and I'll likely change them at some point but they are working and give me much improved weight transfer off the front (and a much better ride on the street).

Thanks NAZ! I will order those bump stops. Dan offers different spring rates and i went with slightly softer than FFR per his recommendation. His fronts also come with the appropriate caps to mount upside down for easy adjustment.
