These QA1 GM Pro Coil Systems are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling. Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications. Adjustable Pro Coil System Features: Available in independent compression and rebound double adjustable, simultaneous compression and rebound adjustable, or drag "R" Series adjustable, Lightweight Billet Aluminum Coil-Over Shocks, High Travel Springs, Easy, Bolt-In Installation, Ride Height Adjustable, 100% Dyno Tested and Serialized, Serviceable and Rebuildable by QA1 Authorized Service Centers, Made in the USA, Used in drag racing, street performance, autocross, road racing and street rod applications, Sold in Pairs, Non-Adjustable Pro Coil System Features: Steel, Stock Appearing Coil-Over Shocks, High Travel Springs, Easy, Bolt-In Installation, Ride Height Adjustable, Used in drag racing, street performance, autocross, road racing and street rod applications, Sold in Pairs

The best phone holders for any car and any phone
Color: Dark Black, Size: 1 Pack
One of the best phone holders I’ve ever used! I’ve used this holder for about a year now and it is perfect for my phone; it’s durable and secure on any types of bumps, won’t mess up the angle whatsoever. It has a small hole on the bottom for charging phones. The installation is really easy; you just hook it on your vent which is great compared to other suction mounts. If this one ever breaks, I am sure to purchase the same one; super worth for money.

Works well on 2003 Corvette.
Color: Carbon Fiber, Size: 2 Pack
I purchased these for usage in my 2003 Corvette convertible. As much as I enjoy the vehicle, they are extremely insufficient for storage. No "usable" built-in cup holder, no pockets and no flat area that can hold a cell phone. The console and glove box are not ideal in this day and age since the phones are used constantly. Enter these excellent little holders. They mount perfectly on the central vent in the dash. If you slide the bases as far as possible to each side and then tighten them down, the base will overlap the non-moving portion of the vent and keep the unit quite stable. I would suspect this is applicable for any vehicle that has the traditional flat vent fins. The holder has a hook that when fished into the vent, clasps over the back of one of the fins. By hooking the fin, once tightened down (careful not to over due this as the vents are just plastic) the installation is as stable as you can ask for vs any of those goofy clamp types that slide off quite easily, especially as they age and sun softens the pads. Benefit from my mistakes on those bad purchases and stay away from clamp mounts. If you have flat fin vents and are looking for a reliable means to mount a phone, this may be just right for you. Best of luck.

Good product, but...
Color: Dark Black, Size: 1 Pack
Easy to install. Like the product. The holder does not hold the phone position. It flops down alot.

The Perfect Phone Mount.
Color: Dark Black, Size: 1 Pack
It’s the perfect size, easy to install, and works perfectly. I have a 15 pro max iPhone, and it fits perfectly.

Well built and removes cleanly.
Color: Dark Black, Size: 1 Pack
Seems to be very solid and it was a little bit tricky to get it located on the vent blade properly, though that might just be due to the vents shape in my Highlander. I really like that it can be easily moved from one vehicle to another if needed without leaving adhesive residue like my last mount did. The only concern I have is whether the vent blade will support the weight long term. Time will tell I guess. EDIT: This fits all of the vents on my 2011 Highlander great. On my 2022 Highlander it will only attach to the center vents and then just barely hooks on after angling the vent blades enough for the hooks to grab. Even then the mount only makes contact at the very top and bottom of the vent opening. It works, but I wouldn't recommend it as ideal.
