Reduce suspension angles on your 2003-2013 Dodge Ram 2500/3500 4WD with the Synergy 8583-04 Front Lower Adjustable Control Arm Kit from GAP. A long-arm suspension upgrade involves using longer control arms that mount further back on the vehicle to reduce suspension angles and bring the truck closer to the stock geometry. The Synergy Front Lower Control Long Arms are adjustable to allow for caster correction and re-centering of the front axle housing for oversize tires and increased ride heights.

Fantastic Fragrance Free Vitamin C
Really nice Vitamin C product. It goes on nicely without any off putting scent. I tried this one after trying another Vitamin C serum my dermatologist recommended, but the consistency and smell of the other one makes this one a dream to use in comparison.
Instead of a dropper, it is dispersed using a pump. The consistency is thin, but not watery. It does not leave my skin feeling sticky. I love not having it drip all over my face. Leaves a nice glow without being shiny.
Time will tell how effective it is at fading brown spots, but as with the other Good Molecules products, this is a great product for a great price.

Great buy and a have to try
This is a very nice vitamin C serum/cream. It spreads nicely, so you do need a lot. A little really does go a long way. I wash my face, apply serums, and then apply this on top before my moisturizer. It doesn't pill up at all for me. In fact, it layers really well. It's dry time is fairly quick, and it's a GREAT value for your money. It's also not oily at all.
I've been using it for over a week now and I can tell my complexion is brighter and the one dark spots are s bit lighter. I'd say it's pretty effective.

Nice creamy texture
I like this serum because it's more like a cream rather than the oily types of serums. It goes on nice and softens my skin. I'll know more over time when I use it longer.

Brightened My Skin and Feels Lightweight
I’ve been using this Vitamin C serum consistently and I really like how lightweight and gentle it feels on my skin. It absorbs quickly without leaving a sticky feeling and layers well with my moisturizer. After a few weeks of use, my skin started looking brighter and more even, especially around dark spots and dull areas.
I also appreciate that it did not irritate my skin or cause breakouts. The packaging is simple and the product feels high quality for the price. A great addition to my skincare routine!
