SunCoast's 10L1000 Category 3 Expanded E & F Capacity Rebuild Kit with Pro-Loc Valve Body Combo includes all the necessary frictions and steels required to replace the clutch and steel in a plate number 10R140 transmission. The kit is specifically designed to provide increased capacity in the E and F clutches. It is a complete clutch and steel module kit that is compatible with the new 10L1000 transmission. This kit includes all the clutches and steels required to successfully rebuild your 10L1000 transmission.

RAYBESTOS FRICTIONS & STEELS

Raybestos Powertrain GPZ friction clutch plates greatly increase transmission performance and durability. This state-of-the-art friction material far exceeds OE material to withstand high stress, high temperatures, and repeated cycling. GPZ's outstanding performance benefits are perfect for heavy-duty vehicles and high-stress driving. Testing of GPZ revolutionary friction material shows that it outperforms OE materials by as much as 20%.

Raybestos Powertrain steel clutch plates are high quality, application-engineered products at a price you can afford. Manufactured with attention to critical tolerances and quality control, our steel plates meet or exceed OE specifications and have a superior surface finish that supplies a greater apply area and friction clutch life. Raybestos steel plates give better shift performance and clutch durability, lowering noise and shudder, extending the life of your transmission.

FEATURES & BENEFITS:
  • Better shift performance and clutch durability
  • Enhanced shift feel
  • Withstands high horsepower
  • Greater torque capacity
  • Maintains piston travel
  • Optimum performance
  • Higher heat resistance
  • Made In USA
  • OE thickness for maximum heat sink
  • Superior surface finish for greater apply area and friction clutch life
  • Meets or exceeds OE specifications for flatness and parallelism
  • Flawless fit without binding

THE EXPANDED CAPACITY E DRUM

SunCoast's Category 3 Rebuild Kit also comes with the 10L1000 High capacity "E" clutch drum with billet apply piston. This high capacity 10L1000 clutch drum arrives fully assembled for effortless installation. The high-capacity 10L1000 "E" clutch drum addresses all of the facets affecting the durability of these clutches in highly demanding driving situations.

To improve clutch life SunCoast first started by simply increasing the clutch count. This 10L1000 clutch drum boasts an astounding 29% increase in clutch capacity compared to the factory drum, surpassing any other aftermarket option on the market today by an additional 15%.

Another key point SunCoast address here is the deflection in the E-clutch. This is especially exacerbated when operating under higher line pressures, often experienced during heavy-duty or higher-load situations.

The SunCoast 10L1000 “patent-pending” E-piston is engineered to eliminate any possibility of apply-deflection or coning. By using superior materials and increasing the apply piston diameter, they have significantly expanded the contact surface area. Crafted from billet T6061 aluminum bar stock and meticulously CNC machined in-house to exact tolerances, this “E” Drum Apply Piston for the 10L1000 embodies SunCoast's excellence in design.

Moreover, they have tackled the issue of rapid drum degradation caused by steel tooth chatter/engagement. SunCoast's solution involves the designing of specialty 4140 steel dowels for the steels to engage with, replacing the highly malleable factory-cast aluminum. This design allows us to ensure reliability while keeping reciprocating mass at a minimum.

The friction material was also addressed as SunCoast has changed from the factory friction material which is engineered and designed to provide maximum "NVH" for comfort. The 10L1000 drum is equipped with Raybestos GPZ clutches.

FEATURES & BENEFITS:
  • 29% more clutch capacity than OEM
  • Billet apply piston diameter enlarged to avoid “clutch cone” by contacting more surface area of top steel 
  • Billet 6061 apply piston ensures minimal deflection
  • Patent-pending design made in-house in Florida
  • 15% more capacity than any other aftermarket drum
  • Steels engage on 4140 steel dowels, instead of the problematic cast aluminum drum assembly

Functional not durable
Color: Grey, Size: 1 Large Panel
When first assembled, it looked exactly like the picture. However, over time, the top bar has begun to bow. The metal bars are weaker than I expected. It is still doing it's job providing privacy but the quality is not quite up to par. The height, color, and functionality are all exactly as described. If you need an inexpensive room divider, this is a great option. I don't expect it to last more than a year or two, but I would still recommend this product for those needing something fast, easy to assemble, and don't need for an extended period of time.

Difficult Assembly and Very Unstable
Extremely difficult to assemble. It seems like the metal wasn't cut well. Some things screw right in, while others will make your hands raw trying. It is true to size, which is great, aside from the fact that with how hard it is to build, disassembling and reassembling for storage would be a nearly impossible task, and it's extremely hard to tuck away anywhere fully built with the size and feet on the bottom. It's also pretty unstable and doesn't stand fully straight, which is a little nerve wracking with pets in the room. I am dreading dissassembling this thing to return it once I have something to replace it, but trust that I will be ASAP.

Didn’t come with all the Parts - Essentially Worthlist Return in process. Huge inconvenience
Product came with everything but the rubber pads that receives the screws so it’s essentially worthless upon arrival. Now I have to go out of my way to go to UPS to send it back and process a return which will take 7 business days until I can receive a refund. I was excited for this package too what a complete let down !
