• What Spring Bars for Equal-i-zer Weight Distribution are Needed for Keystone Springdale 1750RD
  If the weight of the trailer is over half the weight of the tow vehicle then you'll need a weight distribution system. The rear suspension on the Ram also uses coil springs which are great but they'll sag more than the comparable leaf springs on a Ford or Chevy. Furthermore, the lighter trailers are typically the ones with sway control problems so I do think a weight distribution system is a good idea for you. That said, an overrated one won't do you any good so you'll want to replace the...

• Recommended Replacement Spring Bars To Accommodate Lighter Trailer
  Your weight distribution system, # EQ37120ET, is rated for a total tongue weight of 800-1200 lbs. That total tongue weight is the loaded tongue weight of your trailer as well as any cargo behind the rear axle of your tow vehicle. I've attached an article on trailer tongue weight to help. If you are at 15% of tongue weight you'll be in that range, but lighter would be a rough ride. I recommend using a scale like # e99044 to determine your actual loaded weight.

• Replacement Bars for an Equalizer Hitch, 14,000 to 10,000 Solution
  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 to swap the head # EQ90-02-1000 in as well.

• Equal-I-Zer Weight Distribution is Too Stiff; Can Lighter Bars be Used in the Same Head
  The different size Equal-I-Zer systems have heads to match the bar sizes so the parts are not interchangeable. But not to worry, with some adjustment you can soften it up a little and not have to use a different system. You will need to lower the tension on the spring bars. To do this you can angle the head towards the trailer and/or mount the parts of the brackets that hold the spring bars one slot lower. This will lower the tension and soften up the ride. Try this first instead of going...

• How to Select Weight Distribution System for Use with Multiple Trailers
  Weight distribution/sway control (WD/SC) systems really need to be tuned to the actual tongue weight (TW) of the fully-loaded trailer, with all cargo and supplies in place and with tanks filled. Different systems have spring bars that are rated for a specific TW range, usually a range of several hundred pounds. It is possible to select a system now for your current pop-up, and when the time comes to get a new larger trailer just change the spring bars to a set that is rated appropriately...

• Best Equal-i-zer Weight Distribution System for 9k GVWR Travel Trailer
  The tongue weight range for the # EQ37140ET is 1,000-1,400 lbs and I'm assuming this is the system you're referring to. We recommend measuring your loaded tongue weight of your setup to see if it will fall in that range. Even with 800 lbs as your dry tongue weight, the system may be overrated. The sway control would work, but an overrated system could cause a rough ride and bouncy trailer. If you measure and find that it does fall into that range then you are good to go. I also see you...
