SRT-4 BC Single Spring with Titanium Retainers.
All products were free of flaw and shipped in an immaculate box I didn't even want to throw away. Had nice advertising stickers in there a long with all the components. All of the springs were nicely stacked and wrapped in paper. The titanium retainers were all individually sealed in their own little zipped bag. Overall, the product was and is exactly as described. The titanium retainers are significantly lighter and look much better. The design and engineering of these products is great. Thank you guys!!
