Installed these KYB SM5640 top hats with Bilstein 5100 shocks and Old Man Emu 2888 front coil springs on my 2016 Toyota Tacoma 4x4. Fit perfect and are excellent quality. Good idea to change them with your shocks to save labor in the future due to squeaking and or knocking from the top hats being worn out.

Fit my wife's 2011 4runner perfectly. Dealer installed the hardware in the incorrect order and had hell trying to narrow down where the vibration was coming from. Finally found the strut mount was toast. They had strut, rubber isolator, washer, mount, rubber isolator, washer, and then nut. Easy fix in my garage with a spring compressor.

I used these mounts when replacing my 4Runner Limited’s XREAS suspension. They feel high quality and work just as they should. These come with hardware, bushings, and a bushing on the bottom molded into the mount so an additional one is not necessary on the bottom. My Eibach shocks came with a bushing that I did not need to use because of this.

Added these to my 2nd Gen Tacoma's Bilstein 5100s that previously had the stock spring hats on them. This improved the ride, the oems were obviously worn out considering how much better and tighter the front suspension feels now. It helped the truck drive like new again.

All the pic's on the sellers page refers to 'mounts', S-being operative. This is very deceiving, you only are buying 1 mount. KYB is a great name, up there with Moog, I expected more accurate (and honest) description. I know, I should have known by the price, 2 for $60-$70. This is the first time buying these and not a lot came up in the search to compare too, ordered another one -cheers5-stars for the quality..

Best price by far compared to other websites and local stores (for same part number). Perfect OEM replacement for my 2006 Tacoma 4x4 4.0 SR5 with aftermarket OME 2885 coils and Bilstein 5100's. Includes all the bushings, including the molded-in rubber bushing found underneath the tophat and protrudes into the center hole, providing cushioning and tight fit around the shock stem.

08 FJ Cruiser 122kmi. OME suspension.I've always had this noise that sounds like two washers smacking together. A sort of light clang with a short but high pitched ping to it. Mostly on down travel of the shock. I suspected sway bar was hitting the spring perch and removed the sway bar. Noise was still there. I then suspected the spring just bottoming out the strut at full extension. I went mad trying to find the source of it and never did. Until my strut isolator bushings started to crack and I replaced the tophats and bushings with these KYB kits. As it turns out. the OEM hardware for the strut isolator bushing and washers around the top hats follow this order bottom to top. Washer>BottomBushing>TophatWasher>Tophat>TopBushing>Washer>Nut.After taking the old tophat out I now suspect that the sound I was hearing was from the washer above the bottom bushing hitting the top hat itself..the OEM hardware uses a special washer to align the strut inside the tophat. This is a metal on metal situation, once the bushings start to go they allow these parts to temporarily separate on fast shock extensions and clash back together.The KYB kits have a bushing that is shaped the same as the old bushing and washer combination. Thus, eliminating this noise all together... Thank you KYB for designing around this. You solved a problem I wasn't really sure I had. I have not heard that annoying sound from the first time I backed out of my driveway since I installed this kit. Highly recommend.
