Best Suspension Upgrade for Keystone Raptor 3712 Toy Hauler Triple Axle

Question

Question:

I have a 2006 Keystone Raptor 3712 Toyhauler with triple Lippert 6K axels. It is time for a suspension overhaul. I am considering the Road Armor equalizers new springs and hardware. The original equalizers are Dexter 13 105 forward and EQ 104 rear. The axels are 33inch apart and the springs are 26inch double eye. What do you suggest?

The Equa-Flex Cushioned Equalizers part # LC279689 is the best suspension upgrade option for a Keystone Raptor 3712 Toy Hauler and what I recommend that you use as it will be a direct fit replacement. The Equa-Flex is pretty much the same thing as the Road Armor which is only for tandem axle trailers.

I was recently able to get my hands on the Equa-Flex equalizers and I must say I was very impressed on how well they performed and how easy they were to install. I have attached a review/install video I did on these below.

For new leaf springs use part # e94SR.

Answer 9

Besides the obvious design differences there isn't much difference in how the E-Z Flex and Equa-Flex #LC279687 work or how well each one works. If I had to quantify it I would say that the Equa-Flex would stiffen things up a little more compared…
