Shimano Sienna 4000 Review - Pros and Cons

If you searched for the Shimano Sienna 4000, the 1st thing you need to know and consider that there are two models that fits that search.

The Shimano Sienna RE 4000, and the Shimano Sienna FG 4000. The main difference between them is the RE has a rear drag while the FG has a front drag, which gives the FG a max of 19lb drag, while the RE has a 7lb drag.

What is drag in fishing?

Drag is the resistance that a fish feels when it’s swimming against your line. It’s what makes it hard for the fish to swim away. There are two types of drag: mechanical and fishing line drag.

Mechanical drag is caused by the friction between your reel’s gears and the spool. Fishing line drag is caused by the tension on your fishing line. The more tension you have on your line, the more fishing line drag you’ll experience.

Rear drag vs front drag

When it comes to fishing reels, there are two main types of drag: rear drag and front drag. Each type has its own advantages and disadvantages, so it’s important to understand the difference before you make a purchase.

Rear drag fishing reels are more common and tend to be less expensive. They have a fishing line spooled around one side of it, while the other is exposed. The fishing line comes off one side of the fishing reel, which makes it easier to cast.

Front drag fishing reels are a newer design that is becoming more popular. Instead of the fishing line coming off one side, it comes from the center. This type is more balanced and doesn’t feel as heavy when you cast it.

The Shimano Sienna 4000 Fishing Reel

The Shimano Sienna 4000 fishing reel has been around for a while and is still one of Shimano’s most popular reels. It comes in both right and left-handed models, making it great for either-handed anglers.

The Shimano Sienna 4000 is a low-end fishing reel that has the Shimano name! Shimano is one of the top brands in fishing, and they hold that reputation for good reason. The Shimano Sienna 4000 is an affordable reel with high-quality components.


Shimano sienna 4000 specs

The Shimano Sienna 4000 is a great reel for the price. It has a lot of features that make it great for fishing.



Shimano Sienna spool is a hybrid Shimano/Nautilus design. It is made of cast aluminum and machined stainless steel. The Sienna 4000 FG has 3+1 bearings, and the RE has 1+1.


Gear Ratio

Both models have almost identical gear ratios. The FG has 5.2:1, and the RE has 5.1:1. This ratio is great if you’re out for smaller fish.


Anti-reverse system

The anti-reverse system keeps your line from pulling out of the spool, and the retrieval rate of both models is 32 inches per turn.



The FG weighs just over 11 OZ (320 grams), and the RE is a bit heavier weight 12.9 OZ. It’s not too heavy that it will weigh you down when out on the water, but it isn’t so light that your line won’t feel stable in the reel.


Shimano Sienna 4000 Line Capacity

The line capacity (Mono) is the same in both models, from 160 yds for a 12-pound test, to 240 yds for an 8-pound test.


Which Shimano Sienna 4000 should you buy?

Since both of them are low priced, I recommend going for the Shimano Sienna 4000 FG.
