The All-New Patented Banks Ram-Air Differential Cover Wipes out the competition! When it comes to product development, we only make products that increase performance and beat the competition.

So when we tested the popular Diff Covers on the market, we were shocked to find out that they actually hurt performance. This lead to the development of something so New and Incredible that our performance design has a United States Patent. Look, when we set out to build a product for your vehicle, we only engineer the best. What else would you expect from a company with a winning legacy that spans decades.

We are here to win, and we just did (Again) in a huge way.

Purpose Built
The Banks Engineering team's goal was to perfect fluid flow and reject BTUs from the fluid as fast as the ring and pinion puts them in. If the fluid flow is impeded in any way, it results in resistance and aeration which reduce fuel economy and creates heat, thereby degrading the fluid and decreasing the lifespan of the gearset.
Outperform the Competition, for less
Thanks to its superior fluid and aerodynamics, the Ram-Air Cover out-performs stock and flat-back high-capacity covers and does so with less lubricant. Increased distance between service intervals and less lubricant means you'll save money while extending gear life.
Key Highlights

  • New patented design features Ram-Air scoops for fastest cooling
  • Provides cold high velocity air, overcoming dead air zone behind differential
  • Scoops force air up and into massive heat radiation fins
  • Engineered to break-away if snagged on an obstacle
  • Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle
  • Cools 118 percent better than flat-backs in 200hp 60mph sustained tests
  • Dry-mount high-pressure silicone O-ring seal. No messy RTV clean!
  • Internal fins transfer heat through the cover into the external fins
  • Clears spare tire heat shield, Panhard bars and other components
  • Does not sacrifice any ground clearance
  • Limited Lifetime Warranty
  • Fluid Dynamics
  • Axle tube lubricant guides directs lube to bearings w/o overfilling
  • Cover mates flush with differential housing for smooth fluid flow
  • Ring gear raceway controls fluid flow to the pinion and bearings
  • Low fluid aeration means longer fluid life

Glad I chose these Sturdy, Fluffy Pillows
Color: White, Size: 18x18 Inch
Took me forever to decide which pillows to buy....Price won out. There might be better out there, but I really can't see how. They plumped up really nicely. I once learned from a manager at a big box dept store when purchasing a goose down pillow how to 'activate' the pillow. Basically, he violently threw the pillow down onto the floor, then proceeded to beat the tar out of it....That's how it's done. I think many ppl don't do a good enough job when they get their pillows. I watched several videos from ppl who have purchased this type of pillow. And quite frankly, they do not know what they are doing....My pillows are very plump and awesome. I purchased the 20" squares and then chose 18" pillow covers to stuff them into. Perfection. Fat, soft, soothing pillows. Me and my Doggo are quite happy to lounge around on these durable puffs of fluffiness.

Excellent Inserts. Great price point.
Color: White, Size: 12x20 Inch
I purchased the 20x20 first and loved them so much, I purchased these the next day. They come vacuum sealed so please do be careful opening them. It takes a little time and patience. These fluff up so nicely. I manipulated by hand a bit then into the dryer with wool dryer balls on medium heat for about 20 minutes. They are odor free which is a big plus for me and the quality is there for the price. I can't use feather inserts for anything so these are the next best I've found at this price point. I will be purchasing more and I do recommend.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable. Filling quantity: They’re nicely filled and give good shape without feeling overstuffed. Durability: They seem well-made and hold their shape well even after daily use. Color: Clean, bright white that works well with different pillow covers. Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.

Exactly what I was looking for
Color: White, Size: 26x26 Inch
I bought these to fill some euro pillow covers and they worked out really well. They come vacuum packed, so at first they look flat, but once you open them and give them a little time, they fluff up nicely. They are soft but still have enough structure to hold their shape on a bed or couch, which is exactly what I was looking for. Not overly firm, but not limp either. They give that full, styled look without feeling stiff. The size is true to 26x26 and fills the covers well without looking saggy. I like that they don’t feel hollow like some cheaper inserts can. Quality feels good for the price. They are not luxury pillows, but definitely a solid option for decorative use and they hold up well. Overall, really happy with them and would buy again for other rooms.

Smells amazingly like cherry, but expect a mess under the feeder.
Style: Wild Bird Food, Style: Wild Bird Food
This is a fantastic budget seed blend to keep your backyard feeders full during the busy seasons. I put a banana in the picture next to this massive 10-pound bag for scale, though I wouldn't recommend leaving the fruit out there unless you want to feed the local raccoons instead. The most surprising part of this bag is the smell—it has a very strong, sweet cherry scent right out of the bag that genuinely seems to bring in the local cardinals and blue jays faster than plain seed. THE GOOD: • The cherry flavoring actually works as an attractant, and the sheer volume of seed you get for the price makes this an excellent value for high-traffic yards. • It brings in a huge variety of ground-feeding birds, especially mourning doves and juncos. THE TRADE-OFF: • This is a "value" mix, which means it contains a very high percentage of filler seeds like milo and cracked corn. Finicky songbirds will actively kick the milo out of the hanging feeder to get to the black oil sunflower seeds, creating a massive pile of rejected seed on the ground. THE BOTTOM LINE: A great-smelling, budget-friendly birdseed that attracts a ton of wildlife, provided you don't mind the ground-feeders cleaning up the mess underneath.
