Wish I read this before ordering mine from TDot... I was opting for shipment from US or local and now I will definitely hold on ordering front struts through the same shop until figuring out how this will go.So now I am needing to do a Paypal dispute because Tdotperformance.ca has stopped answering my requests for a refund. I won't ever be buying from them again. 0 Stars rating for customer service.
I also had the same problem with KYB strut mounts (popping and binding sound)....I would go with OEM Honda as well.I started this thread last year when I just replaced the rear shocks. I finally got around to replacing the front struts with the B6 and installed new KYB mounts. What an incredible improvement in the ride and handling of my Pilot now. I also put four new discs and ceramic pads (Bosch Quietcast) and bled the brakes flushing about a quart of fluid and completely removing all of the 10 year old brake fluid. I'm so happy with the way this thing rides now, it's better than when it was new! The Bilsteins made a huge improvement in the ride and handling.
One little quirk I noticed is that the original dust boots are integrated into the upper rubber spring seat - it's all one piece unlike other designs that use a separate spring seat and dust boot. I simply cut the boot material leaving just the spring seat intact and installed an aftermarket dust boot. However I am having a slight issue with the springs binding after the car is parked. When I first turn the wheel I can hear a pop, and visually confirmed that the spring is twisting but the mount doesn't move right away and then it eventually moves and pops back into alignment. I'm going to remove the struts and replace the dust boot and rubber spring seat with the OEM Honda part - they're only $15 each. I might also try a different strut mount since I'm not sure why this KYB mount isn't turning and is allowing the spring to bind.
Did you use the OEM springs or upgrade those as well? Did this change ride height at all? I found a website selling B5100s they said would fit my 2015 Pilot. I'm a little skeptical of that. It's quite a bit different under my new pilot compared to my old 2002 4runner.My rear shocks have been leaking for quite some time, but just recently I noticed that my Pilot wasn't handling well. Whenever I would go over railroad tracks or other odd dips or bumps, the car would have a strange floating feeling with a squishy/loose feeling in the rear so I figured it was time to replace them.
I was considering the KYB shocks for around $50 each, however I noticed that Bilstein made a B6 shock for the Pilot for around $80 but they were backordered at the time. So a few months ago I placed the order, and once they were in stock they shipped. I just finished installing them about two weeks ago and so far I'm very impressed. The ride and handling is almost back to what it was like when new, however I'm certainly feeling the weakness of the front struts now (100K miles on them) so they're getting replaced next. The B6 are a monotube design, allegedly better than the twin tube design of the B4 or the KYB Excel-G. Time will tell how these hold up, but so far I'm very happy with the improvement.

I did read a few horror stories regarding the lower bolt seizing up when trying to remove the original shocks. I started on the passenger side and it came off without issue. Despite my Pilot never seeing snow/salt and very rarely even being driven in the rain, the lower bolt on the drivers side was a bit difficult to remove. It wasn't seized to the point where I had to cut the welded nut to remove it, but it required more effort than the passenger side. It looked like some galvanic corrosion with a white crust on the bolt and threads. I zipped it on a wire wheel to clean it up and added some anti-sieze before reinstalling it.
