Works and looks good, just doesn't work well with lc9 coils, you'll need spacers or washers for it to seat right

Everything bolted up perfectly with the stock valve covers. Comes with all the hardware to mount the bracket and the coils. Little tip when reusing the old coil harness is to put it behind the bracket when bolting up to hide the wires. Would buy again for another LS build!

Bought for my truck and to use ZZP LS coils and had to order spacers and bolts kit separately because they won't fit with the bolts that they came with..

Its very clear people are buying the wrong brackets and not using the reference guide for which coils they have. The bracket is great. Not 1 issue installing it in my 2013 camaro SS, if you READ you will need a spacer kit for certain coils. The provided bolts were great as well.

They came sealed with instructions and hardware in a thermo sealed bag like a professional product should. They work with LS truck coils and move the coils down to center them over the valve cover. Install took like 10 minutes max. Only thing i dont care for is the ICT logo right in the middle. But whatever. It's not a complete deal breaker. Also be careful on tightening them. I didnt have any issue, but the "feel" wasn't confidence inspiring. Not sure if it was the hardware or the bracket that caused that. Didnt look into it.

Works great to lower the coil packs after I installed an LSA on my LS3. I bought the extended bolt kit as well.I accidentally pinched my wiring harness when tightening this down cutting several wires. Cost me $80 to replace. Learn from my mistake and be carefull when tightening it down!

Very nice and fit good BUT, it needs longer bolts and spacers; I used 4-5 small washers and 1 locknut to level the coil so it wouldn't lean against the bracket. You can even see in the product image that the coils are sitting on a bracket already (not included). Cost me 8$ for 20 M6 x 30 bolts and I had the washers so not bad. Good product still.
