Replacement Equalizers and Shackle Straps for 2007 Keystone Raptor 3712  

Question:

I have a 2007 raptor 3712 triple axle. With 8,000lb axles. It’s time to redo the shackles and equalizers. Would like to upgrade to newer style . Looking for help ordering the correct stuff. Front to middle axle measures 32 1/2”. Middle to rear axle measures 33 1/2”. The rear equalizer measures 7” center to center bolt. The front equalizer measures 5 3/4” center to center bolt. The shackles are 2 3/4” center to center. Any help would be greatly appreciated.

Thank you for all of that excellent information and photos!

To replace the front equalizer you need the Curved Equalizer # TREQ104 and then for the rear equalizer you need the Equalizer for 1-3/4" Wide Double-Eye Springs # TREQ105. To replace your 2-3/4" long shackle straps use part # TRSL275.

While you're replacing everything it would be work swapping out your bolts as well. To do this you need a 9/16" diameter bolt that's 3" long like the Redline # 126B2.

If you're looking to do an overhaul and upgrade as opposed to just replacement then I recommend checking out the MORryde Shock Absorbing Suspension Equalizers for Triple Axle Trailers w/ 33" Wheelbase # MR59ZR. This looks a little different than what you currently have but it's designed for an 8K triple axle setup with a 33" wheelbase (33" from center of axle to center of axle). We've experienced nothing but good from the MORryde suspension upgrade kits so I know you'll be happy with this performance.

If you go this route then I recommend using the MORryde Suspension Upgrade Kit # MR86ZR instead which comes with 2-1/4" long shackles and everything you need to get it all installed.

Attached are some review videos for you to check out.
