The easy 30 minute install of the new updated "Blue Spring" will increase your fuel pressure back up to where it should be from the factory. Most 6.0's see an increase of 10 psi of fuel pressure. The added fuel pressure will help keep the injectors from outflowing the stock fuel pump, meaning no air in the injectors, and an injector that will live much longer. Most trucks will actually quiet down a little at idle, rev up a lot quicker and with the added fuel pressure, a little quicker spool up on the turbo. The kit does include all the O-Rings and hard parts to rebuild the fuel pressure housing. Another major bonus is that this block has an adjuster screw in it. This will allow you to bump pressure up a little for big injectors. Or after the spring settles after years of abuse, just loosen up the jam nut, and run the adjuster screw in a turn or two to get your fuel pressure back to where you want it. Everybody has their own opinion of fuel pressure in a 6.0L Powerstroke, why not choose for yourself, we recommend setting it between 55-68psi. This kit also comes with a Brand New Billet Aluminum housing to keep the regulator spring set and to prevent leaks from the housing. This is a much thicker, stronger billet piece than the factory Cast Aluminum spring housing. The factory unit is known to leak or "weep" fuel from the sides. This kit will also help clean up the look of the factory filter housing as well., Note: NOT Compatible with E-series., Features:Anodized in Sinister Blue, CNC Machined from T6-6061 billet aluminum, Laster etched Sinister Diesel logo, New "Blue Spring", New Gaskets, Adjustable fuel pressure so you can fine tune your performance, Restores lost fuel pressure from a worn spring, Helps save Injectors from low fuel pressureIncludes:(1) Sinister Diesel Billet Spring Housing, (1) New "Blue Spring", (1) New Gasket/O-ring set, Installation Hardware.

Adorable! 🥰

Can be a little uncomfortable if you’re a wide foot girly but overall comfy. A little slippery after lotion and some heat (I live in the muggy south), I’d possibly size down. Once you break them in they’re a little loose, at least for me. I usually wear a 6.5-7 I got a 7.5 to accommodate for the width. I could’ve done with just a 7.

My favorite

I'm absolutely in love with these heels! They are even more beautiful in person-the rhinestone bow adds the perfect touch of sparkle and elegance. The fit is comfortable, and the ankle strap keeps them secure while walking. The heel height is just right, giving a classy look without hurting my feet. Perfect for weddings, parties, or any special occasion. I received so many compliments-highly recommend!

Simple and sexy
Size: 8.5, Color: White/Pat
I love the shoes. They were true to size, and no hang over in the front. I did a lot of walking with these shoes. Very comfortable throughout the night.
