SunCoast's Category 4 48RE rebuild kit includes everything necessary to build your 2003-2007 Dodge 48RE transmission well beyond the capability of the factory 48RE. This high-performance rebuild kit is for customers seeking significant improvement over the stock transmission along with improvements to the band, band actuation, servos, accumulator piston, torque converter, input shaft, output shaft and forward drum. The addition of the billet intermediate servo, billet band anchor and billet band strut allow this kit to address the common known deficiencies of the 48RE. SunCoast's kit also comes with a new billet blueprinted 4.4 band lever. A new thrust washer kit also contains selections for setting endplay.

The 23-Spline Triple Disc Billet Torque Converter that comes with this kit comes with a 2,000 RPM stall speed. The torque converter is lined with carbon graphite clutch material and equipped with a precision CNC machined forged billet apply piston to ensure no deflection occurs.

The Category 4 kit also includes SunCoast's one-piece billet 23-spline input shaft. The shaft is crafted from 300 maraging steel and is then heat treated and stress relieved to handle the additional demands of higher torque and stress loads. Fitment isn't an issue as the shaft is precision ground to make it a true drop-in replacement.

Included in the kit is also a band upgrade. While some other SunCoast kits include a Raybestos Pro Series carbon fiber flex band, in this kit they use a billet rigid band. This band is CNC machined from billet steel and then lined with carbon graphite lining to ensure unmatched performance even by other manufacturers.

SunCoast's Category 4 rebuild kit also includes upgrades to the flexplate. The factory 48RE flexplate is replaced with a SunCoast one-piece billet unit. The billet 48RE flexplate exceeds 29.3 SFI certification which is the standard for racing and sled pulling. The billet one-piece design is CNC machined from a single forging, and specific reliefs are machined out between the converter mounting area and the crank flange to enable minimal designed torsional flex.

SunCoast Category 4 rebuild kits replace the factory cast pistons with new billet apply pistons. The direct piston is also included with new custom calibrated springs while the forward piston is replaced with a new billet piece. These two improvements allow higher clamping forces without any deflection occurring. Giving a much more direct shift feel and eliminating potential cross leaks within the drum.

Another piece included in this kit is a full billet rear clutch retaining hub, made from 4140 heat-treated, stress-relieved billet steel versus the OE cast piece. The factory cast retainer is known to fail in high torsional fatigue situations such as higher line pressure, commercial use and heavy duty towing and hauling. This new billet piece is stronger, more reliable and is the performance correction you've been looking for.

Lastly, a billet output shaft is added to the Category 4 kits. Designed for higher horsepower/torque engines, this performance product has been tested in excess of 1,400 ft/lbs of torque. The shaft is machined from 300M material then heat treated for torsional strength and precision ground on all critical diameters.

I Smell Like a Gentleman Who Owns a Fireplace
Scent: Bourbon Oak, Size: 16 Fl Oz (Pack of 1)
The fragrance is warm, woody, and slightly sweet...that low amber note that smells expensive without trying to smell expensive, which, as we all know, is the actual expensive smell. My wife walked past me twenty minutes post-shower and said, unprompted, "You smell really good." I nodded like I had planned this. The lather is genuinely rich; squeeze a modest amount and it blooms into a thick, creamy foam that covers everything efficiently. The texture is silky rather than watery, which matters more than people admit. Watery body washes feel like rinsing off with slightly scented regret. This one feels intentional. It cleans, and your skin actually feels clean afterward, not just rinsed. And the moisturizing? I wasn't expecting it. No greasy film, no lotion-begging dry patches by midday. Just quietly softer skin that doesn't make a big announcement about it. Now, my honest gripe: the scent longevity has a ceiling. By mid-afternoon you're back to neutral. That's the gap between four stars and five for me. For daily freshness and an incredible morning window of smelling genuinely great, it absolutely delivers...but it won't carry you to bedtime. On value: 16 fl oz is decent, the lather is efficient so the bottle lasts, and the price sits in that sweet spot where you feel like someone who makes slightly elevated but still reasonable choices, which is exactly the vibe this entire product is going for.

Lathers great in a small amount!
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1), Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
Lathers great for a small amount! A fair price for the amount and rich content. I just bought, used and love it. Definitely will purchase again. I love the sophisticated yet sensible smell doesn't overpower. In my perception it is a unisex scent as I am a woman and bought for myself.

Smells Like You Have Your Life Together
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
Cremo Body Wash with Italian Bergamot, Neroli Blossom, and Fresh Vetiver smells far more expensive than it has any right to. The scent hits that sweet spot between fresh and refined. The bergamot gives it a clean citrus lift, the neroli adds a smooth floral edge, and the vetiver grounds it with a subtle, masculine depth that does not scream but absolutely speaks. The lather is rich and concentrated, so you only need a small amount. It feels more like something you would find in a boutique hotel than on a regular store shelf. The fragrance lingers just enough to be noticed without overpowering your cologne or filling the entire room. If you want to step out of the shower smelling like competence and quiet confidence, this one delivers. It is polished without trying too hard, and it makes everyday showers feel slightly upgraded.
