Average Customer Rating:  4.8 out of 5 stars   (47 Customer Reviews)

by:

Everything fit perfect. my only minor issue was that I was expecting the lock nuts to have a nylon insert to prevent loosening. After a little google research, I realized they were lock nuts, indicated by a very small indent on 2 sides of the nut. Apparently, this ever so slightly deforms the nut to make it not loosen once torqued on.




by:

replaced right side on trailer and will finish left side tomorrow everything fit perfectly what would you suggest for the torque spec for the bolts i will see how long this Chinese stuff with last
Thanks art




by:

The holes in the shackle straps are punched out. Holes often require reaming to get the bolt through them.

Perfect replacment parts, really needed it, thanks




by:

These suspension kits include the same, or better, quality parts as are available at a national farm supply store at less than half the price. Probably because all of the parts are sold separately at the chain store.

  • Recommended Suspension Kit With 7-3/4" Long Equalizers for 1-3/4" Wide Leaf Springs
    It sounds like you need the Suspension Kit for Tandem-Axle Trailers part # e99ZR which contains 7-3/4" long equalizers, 9/16" bolts, and 3-1/8" long shackle straps. The kit is designed for 1-3/4" wide leaf springs. I would be willing to bet you have 9/16" bolts instead of 1/2" which are very uncommon. Furthermore, shackle straps are not measured end to end but rather from the center of each hole. If you do indeed have 1/2" bolts and 4" long shackle straps (hole to hole) we would not have...

  • How Tight Should Shackle Bolt Nuts Get on Trailer Suspension
    Shackle bolts don't typically have a specific torque value. They're usually tightened until the knurled portion of the bolt pulls completely into the shackle strap and the bolt head is ran all the way down to the shackle strap and you have at least 2 threads extending past the face of the nut. This allows the suspension to move like it needs to since it's not tightened down, but the lock nuts keep the bolts from unscrewing.

  • Will Trailer Suspension Kit part # e99ZR Replace 2-1/2 inch Shackles
    The shackle straps of the # e99ZR are shorter at 1-3/4 inches than what you have now but that wouldn't be an issue. The slight length change would not be a problem.

  • Determining Correct Replacement Shackle Straps For 2010 Cruiser RV Shadow Cruise 18' Travel Trailer
    Thank you for providing all of that information! The correct replacement shackle straps for your 2010 Cruiser RV Shadow Cruiser 18' Travel Trailer is the Replacement Standard Shackle Link # LC122487 which measures 2-1/4" center to center of the 9/16" holes so it will be right at 1/8" shorter than your current shackle straps, but is the closest option and will work perfectly. I included a video of the # LC122487 for you to take a look at.

  • Recommended Lift Kit for 2012 Keystone Cougar XLite Fifth Wheel
    We have a solution for you but because your axle is already over slung and you have taller hangers in place, we are limited in options. From the images you forwarded, you have a T44 axle. I recommend the Correct Track Trailer Alignment and Lift Kit for tandem axle, # RR23QX. This raises the trailer height by either 1-1/4" or 2-1/4" working with your existing leaf spring suspension system. The brackets attach to hangers and supply new, lower mounting point for springs, which results in...

  • Will 7-3/4" Long Equalizers Work In Place of 6-1/2" Long Equalizers
    The correct replacement 6-1/8" long equalizer is the part # TREQ356, not the part # TREQE34 which is 7-3/4" long. Therefore no, the two are not directly cross compatible. If the reason you are wanting to use 7-3/4" long is so you can get the kit part # e99ZR, you can use all the shackles and bolts with the above TREQ356 so getting both is what I recommend as there isn't a kit that comes with the TREQ356.

  • Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers
    There is a heavier duty version of the etrailer Suspension Kit for Tandem-Axle Trailers item # e99ZR and it has the wet bolts and bronze bushings you are looking for. It's the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers item # K71-449-00.

The Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double Eye Springs - 3-1/8" Links # e99ZR and Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double Eye Springs # K71-359-00 are also for this same spacing.

  • Replacement Trailer Equalizer Kit for Equalizer that Measures 7-3/4 inches
    For a cushioned set of equalizers that have 7-3/4 inches between the side holes we have the part # K71-653-00 which comes with new bolts, shackle straps, and bushings. The shackle straps of this kit are 2-1/4 inches from bolt hole center to bolt hole center. Or for a standard equalizer kit that is not cushioned we have the part # e99ZR. This also comes with bolts and shackle straps. This has 3-1/8 inches between shackle bolt hole centers.

  • Availability of 7-3/4 inch Equalizer Kit with 3-1/8 inch Long Shackles
    The lengths of the shackles that come with the equalizer kit part # K71-449-00 that you referenced are 2-7/8 inches measured from hole center to hole center. If yours are currently 3-1/8 inches this change would slightly lower the height of the trailer but it would still work. To match the shackle lengths and also be the thicker style you'd need the kit # MR76ZR with the # K71-655-00 which is cushioned. Or for just a standard equalizer and shackle kit you'd want the # e99ZR.

  • Replacement Equalizer Kit for Tandem Axle Boat Trailer
    The # e99ZR is designed for 33 inch axle spacing, center axle to center axle. The kit uses 4-1/4 inch tall, 7-3/4 inch long equalizers (measured center hole to center hole). The shackle straps provided are 3-1/8 from center hole to center hole. If that matches your current equalizer/ shackles, the kit would be a fine choice. The # K71-359-00 Dexter Heavy Duty kit features wet equalizer bolts with the zerk fitting. Keeping the suspension properly lubricated helps extend its life, and is...

  • Replacement Equalizer, Shackles and Wet Bolts for 20 Foot Trailer with 7-3/4 Inch Wide Equalizer
    I have a solution for you, but the Dexter # K71-359-00 is not going to be a fit since the equalizer is only 5-3/4" wide. You could use the Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double Eye Springs - 3-1/8" Links # e99ZR, which has the correct size equalizer but does not come with wet bolts and the shackle are also slightly shorter than your 3-1/2" shackles; the shackle length won't be an issue since shackles can stretch over time but if you wanted a wet bolt kit it would...

The Dexter E-Z Flex Suspension Kit # K71-653-00 contains a cushioned Equalizer along with all the bronze bushings, wet bolts and shackle straps needed.
