A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. These springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the “floating” feeling so common with the A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA. As an industry leader in the muscle car suspension industry, UMI is proud to bring you the best spring in the business. Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your car sits properly for years to come. Linear spring rates (530 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling. No more floating feeling. Suitable for Pro-Tour, Auto-x and general cruising.Shipping Notes

As an SLP I love this simple engaging book
Format: Board book
Speech path here. I love this book. It was one of my son’s favorites and what I used to help him produce more words from 1-2years. He was my slowest to talk but loved the engaging sounds in this book. It’s simple but you can add a lot of info or new comments each time you read it with encouragement for your kiddo to produce simple early developing sounds. I utilized pausing with it too to tie my son the chance to produce the sounds. I gift it often now! Just wish it was a tadddd cheaper.

Fun and interactive.
Format: Board book
My one-year-old granddaughter loves this little book. There's no story, but it's interactive and fun, and the illustrations are cute and colorful. She enjoys doing all the things on the pages - knocking, waving, blowing, etc.

Great interactive book for Littles
Format: Board book
This book is so cute and very interacting. Some of the pages are a little confusing on how we are supposed to react, but overall it’s a great book. The beginning has some instructions and tips to help your little speak so that is very helpful.
