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.

Durable duck toy for man’s best friend
Although it was suggested that this toy would be best for small breeds, I found that it’s durable enough for my 80 pound Irish setter! It has literally become his best friend. He takes it everywhere he goes! There’s a small squeaky noise that comes from the neck area that he has to work to find. I’m sure he will eventually destroy this as he has with all his other toys, but it’s really holding up much better than anticipated. It is well worth the $10 cost.

Really cute, well made dog toy. Was a huge hit with our pup
This toy was a big hit! Pros - love the heavy duty burlap-kinda fabric. Our new puppy has razor sharp teeth but this fabric is holding up really well. - size is great for a variety of breeds - shape is perfect for grabbing onto. Our puppy especially likes picking it up on the neck where the toy is more slender - the extra little feet and wing flaps add some interest that have really kept her occupied Cons - the squeaker is in the neck where the fabric has embellishments and is a little thicker. It's a little hard to activate the squeaker but maybe the toy/stuffing needs to get broken in more and then it will be easier to squeeze that section

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball
Size: Medium, Size: Medium
Does your dog destroy tennis balls in seconds? Yes? Then your dog NEEDS this ball! It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground. My dog has been literally playing with this ball all day and not a single mark on it! The only bad thing is that it does not float. Definitely worth the money! Put it in your cart!
