Upgrading the Equal-i-zer Weight Distribution System

Question

Question:

I have the equalizer sway trailer hitch setup rated at 1000 LB. My trail TW is 1130 per manufacturer. Should I upgrade to 1200 LB and if so will buying the replacement bars do the trick? I am pulling with a 2013 Ram 1500 4x4 with a 6inch suspension lift. I also added Airlift 5000 bags in the rear to support the added weight as needed.

Yes, you are correct in that you will need to upgrade your spring bars if you have exceeded the tongue weight capacity of your weight distribution system. However, the Replacement 1,000 Lb. Spring Bars for Equal-i-zer Weight Distribution Systems part # EQ90-01-1099 are 1-3/8" wide and the the Replacement 1,200 Lb. Spring Bars for Equal-i-zer Weight Distribution Systems are 1-1/2" wide.

Therefore in order to upgrade the Equal-i-zer Weight Distribution System w/ 4-Point Sway Control part # EQ37100ET to a system capable of handling up to 1,200 lbs. of tongue weight you will want to replace both the head and spring bars using the Replacement Head for Equal-i-zer Weight Distribution Systems part # EQ90-02-1200 and the Replacement Spring Bars for Equal-i-zer Weight Distribution Systems part # EQ90-01-1299.

In addition to head and spring bar replacement, if your Equal-i-zer hitch was made in the last two years then you will also need to replace the shank using the Equal-i-zer Weight Dist Shank part # EQ90-02-4100.

Answer 1

The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached…

Yes, you can just replace the spring bars and head of your current system to change the weight rating. All you would need is the part #EQ90-01-1099 for a set of bars and #EQ90-02-1000 for the head that are rated lower at 1,000 lbs tongue weight.

The 10K and 12K Equal-i-zer Weight Distribution Systems like part #EQ37100ET and part #EQ37120ET use different heads and spring bars so if you wish to switch back between the two capacities you will need both of these items which I have listed for…

I reached out to a representative of Equal-i-zer, who told me that the sockets from the 1,200 lb tongue weight head #EQ90-02-1200 will not fit in a 1,000 lb tongue weight head #EQ90-02-1000 because they are too big. If you need additional sockets for…

Answer 5

You are using an Equalizer kit that is rated way to high for your trailer. It's not going to function properly and would be why your towing experience feels "off". The lower rated 1,000 lb max bars part #EQ90-01-1099 would be better. It…

Answer 7

It is possible for some spring bars to be interchanged based on their size, but that won't increase a weight distribution system's capacity without adding the appropriate head unit. The replacement spring bars that are rated for 1,200 lbs TW…

Answer 8

Yes, if you use a weight distribution system that is rated too high for the tongue weight of a trailer the ride quality will be incredibly stiff and harsh. You want to ideally pick a system that has a tongue weight range where your tongue weight…

Answer 9

The head assembly and spring bars are different on the Equal-i-zer 12K when compared to the Equal-i-zer 10K so you will need both the Head part #EQ90-02-1200 and Spring Bars part #EQ90-01-1299 to upgrade capacity. The rest is the same so you can…

Answer 10

You would not be able to simply replace the spring bars on your Equal-i-zer #EQ37060ET weight distribution hitch. Instead you would need to get both the 1,000 lb tongue weight spring bars #EQ90-01-1099 as well as the 1,000 lb head unit…

Answer 12

At one point Equal-i-zer bars could be swapped easily to convert a kit to a higher/lower tongue weight range, but we now know that you have to replace the head of the unit with the bars. So with the bars part #EQ90-01-1099 that you need you will need…
