Steeda noticed a lot of Mustang owners had rear subframes misaligned from the factory, by up to 17mm either way. Steeda went to work and created our must-have S550 IRS sub-frame alignment kit! After all, who wouldn't want their rear subframe locked centrally where it belongs? Homologated / Certified for European use

The S550's subframe mounting holes are very large compared to the subframe mounting bolts. Since there is a large difference in bolt and hole size, the subframe can be mis-aligned from the factory up to 1/2" left to right.

The Steeda S550 Mustang IRS Sub-frame Alignment Kit is made from CNC-machined Delrin to avoid putting two dissimilar metals next to each other, preventing corrosion. Delrin is also less weight then aluminium or steel inserts and therefore keeping performance in mind. The Delrin sleeves slide into the sub-frame mounting holes, and fill the extra space left between the subframe mount and bolt from the factory.

Our Steeda S550 / S650 Mustang IRS Sub-frame Alignment Kit guarantees that the sub-frame will be bolted to the same location every time it is lowered. Eliminating the need for unnecessary alignments.

Note: An alignment is needed upon installation due to the fact it could have been misaligned from the factory and with it now being squared in the chassis, some adjustments might need to be made.

Solid Affordable Duvet Insert Comforter
Color: White, Size: Queen
This is a great affordable all-season duvet insert comforter. There are multiple tie downs to attach to the duvet cover, not just the 4 corners. It is soft and washes well. It's plenty warm in the cold but might be too much during the hotter months. I live in San Diego where the average yearly temperature is at least 70 degrees. During the majority of the year this comforter ended up being too warm for me. I've used it for nearly 2 years but just replaced it with the much thinner Bedsure cooling comforter. If you're a hot sleeper or live in a warm climate, I'd recommend that product. This is still a good comforter, just not for me.

Must have!
Color: Light Grey, Size: Queen
⭐⭐⭐⭐⭐ This comforter is absolutely amazing! It feels like something you'd find in a luxury hotel—soft, lightweight, airy, and incredibly comfortable. It has quickly become one of the best purchases I've made. The quality exceeded my expectations, and it's perfect for staying cozy without feeling too heavy. My kids love it so much that they're constantly trying to steal it from me! If you're looking for a comfortable, high-quality comforter, I highly recommend this one. You won't be disappointed!

Cozy, warm and not heavy
Color: White, Size: Queen
This blanket is great and for a fair price, so fluffy and it’s on the warmer side but not heavy, which is exactly what I wanted!

Not Bulky, Not Too Warm
Color: White, Size: Twin
This is a great comforter. I have purchased others that were way too bulky. This one is perfect. It is lightweight and seems ideal for warmer temperatures. I am not too hot in the middle of the night. We are heading into Summer but I am sure this will be fine for Summer heat or for Air Conditioners.
