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.

could be improved but great for price
Color: Tie-dye Purple Rainbow, Size: King (108" x 90")
I have a faux fur throw from bedsure and I wanted one in a queen size as a blanket. Sadly, the bedsure company doesn't make one large enough, so I bought this one. It is thinner than the bedsure, definitely. The velvety backing is thinner and so is the fur itself. And like people say, the back and front layers are not attached. I haven't washed it b/c I decided to return it. I think for the price, tho, it's pretty adorable. If you're using this as a decorative cover -- it's totally worth it. The purple rainbow has very pretty muted colours, with splotches of bolder colour in some sections. I actually like that, and think it would make a charming gift for a young girl. It wasn't quite what I wanted, but I do think for this price point it's lovely. Very soft, does have a nice weight to is, and can function as a blanket if you've got something else underneath. I do think the manufacturer ought to attach the layers (the bedsure one has layers attached!) -- that won't really cost more, and it'll fix many people's complaints.

Lucious, Gorgeous, silky & pillowy
Color: Cream White, Size: Throw (50" x 60")
High End Quality!!! I just unpacked and draped it over a railing-to just look at in Awe & then the feel. I imagine it feels like your in Heaven-on the wisps if clouds. Not thin, I remember my mom wrapping herself in mink (in the day before they knew better), but the Luxury of both feel and the look-OMG I got the white cream bubble. 2) only complaint is generic wash label. I wish there was a brand Label “Lotus Karen”. To the business company, 🙏Please consider putting your brand name on the Label. It’s outstanding!!! Claim your name for the outstanding quality you have in these throws and blankets. Large 50 x60

Super Soft, warm and looks beautiful
Color: Khaki, Size: Queen (90" x 90"), Color: Khaki, Size: Queen (90" x 90")
Super soft. This is my 4th faux fur blanket and this one is by far the softest. Makes it a bit slippery it's so soft but not issue for me. Color beautiful and depending on the light ranges from a bone white to a khaki. Looks expensive. The velvet reverse side also very soft and cozy. Fluffed up beautifully after 20 minutes in dryer when first received. No shedding.Looks great as comforter on bed.

A Must-Have for Cozy Comfort!
I recently purchased the Serenhom Super Soft Cozy Faux Fur Plush Throw Blanket, and I am absolutely in love with it! If you’re looking for a blanket that combines luxury with comfort, this is the one. First of all, the texture is incredibly soft. The faux fur is plush and velvety to the touch, making it perfect for curling up on the couch with a good book or during movie nights. It’s lightweight enough to use year-round but still warm and cozy, especially on chilly evenings. The quality is also impressive. Even after several washes, the blanket has maintained its softness and hasn’t shed at all—a major plus for a faux fur throw. The stitching is strong, and it holds up well to daily use. In terms of aesthetics, this blanket adds a touch of elegance to any room. Whether you drape it over your bed, couch, or favorite chair, it instantly makes the space look more inviting. Overall, I highly recommend the Serenhom Super Soft Cozy Faux Fur Plush Throw Blanket to anyone looking to add comfort and style to their home. It’s a perfect gift for yourself or a loved one!
