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.

Ask the Experts about this etrailer Trailer Leaf Spring Suspension

  • Do You Have a Tandem Axle Suspension Kit with 5.75" x 2" Equalizers
    Yes the Suspension Kit for Tandem-Axle Trailers part # AP233 has the 5.75" x 2" equalizers you are looking for included. Check out the video I linked on it for you.

  • 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...

  • 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...

  • 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.

  • Suspension Replacement For Stock Trailer With 26 Leaf Springs
    To refurbish the suspension on your 1970 Champ Stock Trailer you will need a handful of items. For a suspension kit with equalizers order the etrailer # e99ZR kit including 2 standard steel equalizers where width is 7-3/4” from center of mounting hole to center of other mounting hole. Includes bolts and lock nuts sized for 1-3/4” wide springs. Suspension kit does not have the size shackle straps that you need so you will want to order 8 TruRyde # TRSL275 straps measuring 2-3/4” on...

  • 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.

  • Compatibility of the Suspension Kit for 6,000 lb Axle
    The Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double Eye Springs - 2-1/4" Links # AP233 is not only for under 3,500 lb axles. It is for 33 inch spacing. 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 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...

  • 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.
