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. UMI’s springs are designed to add modern handling and a crisp ride while maintaining the factory muscle car appearance. The rear 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 and general cruising. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.This Part Fits:

Good quantity
Color: A-shiny Brown
Perfect size for me. The different compartments makes it easier for organizing.
Has a mild order but after turning it inside out and put it in the sun for a few minutes, problem solved.

It’s a YES from me!
Color: B-brown
I absolutely love this purse. And I’m so heartbroken because something got spilled inside of it and it affects the functionality of the person on the inside and it makes me so sad but I still use it anyway because there’s one side I can use completely and half a side I can use on the other side lol. It is very good quality. The storage is A+. It is definitely a good value for the price. I was skeptical at first as we all are ordering a purse off Amazon, that is not real leather, but it’s supposed to be good quality. It didn’t really have much of a smell. I actually don’t use the strap provided since I seen that the straps could be interchangeable, I used my strap off my previous purse instead, and now I love it love it! 😍 I get compliments on it all the time!

surprised me
I absolutely love this shoulder bag! The quality really surprised me and in a good way. The faux leather has such a smooth, polished look and feels soft but still very durable. It honestly gives that high-end vibe without the expensive price tag. The size is perfect for everyday use. It’s roomy enough to fit all my essentials like my phone, wallet, keys, and even some extra items like makeup, but it doesn’t feel bulky or oversized. I also really appreciate the inner pockets because they help keep everything organized instead of just throwing everything into one big space. Another thing I love is how practical it is. The material is water-resistant, which is a huge plus and if anything spills or it gets a little wet, it’s super easy to just wipe clean. It still looks brand new after using it regularly. The design is simple but very stylish, which makes it easy to pair with almost any outfit. I’ve worn it casually, out running errands, and even with more dressed-up looks, and it always works. It’s definitely one of those go-to bags you can grab every day. This bag is a great mix of style, functionality, and durability. I’m really impressed with it and would definitely recommend it if you’re looking for a cute, everyday handbag!

Perfect Everyday Bag That Goes with Everything
This purse is everything! I love the size, the material, and the fact that it has the perfect amount of compartments to keep everything organized without feeling bulky. It’s officially become my everyday bag.
The strap is the perfect length and feels really sturdy. It’s cute enough for casual days but also works for going out to dinner, which I love. I’m always looking for something versatile since I don’t like switching bags all the time, and this one checks all the boxes.
The zipper is smooth and feels durable, not flimsy at all. Overall, it feels well made, looks great, and holds up to daily use. Definitely a great find!
