Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.
Leaf springs are an integral part of your trailer suspension system. The leaf springs provide the attachment points for your trailer's axle, suspending it from the frame of your trailer. Each spring flexes to absorb road shock as you travel, allowing the axle to move somewhat independently of the rest of your trailer. This helps to reduce wear and tear on the trailer and also ensures a smooth ride.
Double-eye leaf springs attach to hangers that are welded onto your trailer. One end of this spring will attach directly to the hanger with a suspension bolt. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs.
To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your trailer. You should, however, replace your shackle straps because they are usually the first component to wear out. You may choose to replace old suspension bolts as well. It is recommended that you replace the other leaf spring in your setup at the same time. Because springs can sag and elongate as they wear, this new spring may not exactly match the old one, and the alignment of your trailer could be affected.
If you are fabricating a trailer, you will need to purchase a hanger kit for installation. To determine the type of hanger kit that you need, you must know the specific type of leaf spring that you have, as well as your axle capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications. Hangers and other suspension components can also be purchased separately if there isn't a complete kit that works for your setup.

Quality parts designed better than OEM, on time/early, no excuses!!
by: Michel 12/05/2022
etrailer was quick to reply to my inquiries and shipped the leaf springs that I required rapidly.
by: Bret 10/06/2022
Made in China, so now I'm hoping they hold up better than my 7K springs did. They also come with plastic bushings, so have to order bronze separately. Size as advertised.
by: David04/29/2022
When the parts arrived the box was destroyed, lucky for me that my new leafs springs didn't suffer any real damage. the down side is that when I spoke with your Reps. I was told that these where made in the USA, only to receive them with made in CHINA stamped all over them with the DEXTER stamp next to P/N.
Comments
I think there was some confusion from the rep on the phone. Another company who sells wheels called Dexstar is an American made company. I am so sorry for the misunderstanding.

If the length matches what you need this would work well for you even though it has a slightly higher than needed capacity.

view full answer... - Will 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles Flex When Weight is Placed On ItIf your 2021 Grand Design Solitude 375RES is loaded when you're taking that measurement then yes, that would be why you're seeing a difference in the length from what you're measuring and what we have listed for the 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles - 24-7/8" Long # DX74XR.

view full answer... - Replacement Leaf Spring Solution for 2021 Grand Design Momentum 397THFor a 7k trailer axle leaf spring solution the best we can offer is the Dexter leaf spring part # DX74XR which is rated for up to an 8k axle and is 24-7/8 inches long. You'd need to measure your current springs to verify if this length would work but it is our only potential solution. You should measure from spring eye to spring eye without a load on the spring. There isn't a way for us to look up what length springs your trailer came with.
view full answer... - Replacement Leaf Spring that Could Work for 16 Jayco North Point 377RLBHLooks like your 2016 Jayco North Point 377RLBH has 7k axles. We only have one leaf spring that would be rated high enough for that with the part # DX74XR which is rated for an 8k axle and is 24-7/8 inches long from bolt center to bolt center. We don't have a way to determine what length spring you have so you'd have to measure yours and see.
view full answer... - Leaf Spring Replacement Solution for Dexter 7,000 lb AxlesWe have leaf springs that are rated for 6k axles and 8k axles like with the Dexter part # DX74XR but we do not have any 7k rated axle springs. You can use an 8k spring though like the part # DX74XR on a 7k axle though as you'd just have more spring capacity than needed. This leaf spring is 24-7/8 inches in length.
view full answer... - How to Choose Correct Leaf Springs For 2011 Keystone MontanaI can help you determine the right replacement leaf springs for your 2011 Keystone Montana, though we don't have any way of knowing what specific ones you need. It's pretty easy though, as what you'll need to do is measure your current leaf springs from center-to-center of the spring eyes, and you also need to know the weight rating of your axle. Leaf springs also flatten a bit over time, so you should go with ones that measure a bit shorter than what you currently have. For example,...
view full answer... - Will Dexter Leaf Spring DX74XR Replace Dexter Leaf Spring 072-100-01Yes, The Dexter # DX74XR will work as a direct replacement for the Dexter 072-100-01 you were looking at. These are the same length, capacity, spring count, and both use bronze bushings. It looks like the Dexter 072-100-00 uses a weird rubber bushing but otherwise is the same dimensions as the above springs.
view full answer... - Does 7k Trailer Axle 8327834 Come with Leaf SpringsOur axles do not include leaf springs. So for 7k axles you could use with the part # 8327834 that you referenced you have the option for the # DX74XR for a 24-7/8 inch spring that is rated at 7k like the axle.
view full answer... - Leaf Spring for Dexter Axle with 7k Weight CapacityFor 7k axle leaf springs like what the Dexter axle part # 8327860 you referenced is designed to fit you'd want the part # DX74XR which is for a 8k axle like what you almost have but would work great still even though it's a little more capacity than you'd need.
view full answer... - Replacement Leaf Spring for 2017 Grand Design Reflection 303RLS with 7k AxleSince we know your 2017 Grand Design Reflection 303RLS has 7,000 lb axles we do have one leaf spring replacement that is the correct capacity with the part # DX74XR but this is a 7 leaf spring that is 24-7/8 inches long from eye to eye. You'd want to measure the length of your current springs to determine if this would fit.
view full answer... - Does Tandem 6k Axles Have Capacity for 13,500 lb TrailerActually no, your axle capacity is 12k and you said you plan to carry 13,500 lbs so you'd be exceeding the axle capacity. The trailer axle # 8327872-EB you referenced has a 7k capacity so as long as it's the correct size it would work well for you. It has a overall length of 94 inches from hub face to hub face and 78-1/4 inches from spring seat to spring seat and has a 4 inch drop. For a 8k axle leaf spring we have the part # DX74XR as well.
view full answer... - What is Length Measurement of 7-Leaf Double-Eye Spring DX74XRI checked directly with Dexter, and from what I saw they have a measurement - taken from center of spring eye to center of spring eye - of 24.8", which is the same as our 24-7/8" measurement for the 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles # DX74XR. The only reference to 25.25" I saw was from a different retailer, and maybe they were talking about the overall length, but it is not the correct center eye to center eye length. As for the U-bolts, yes, a 7k Dexter axle and the...
view full answer... - Heavy Duty Leaf Springs and Cushioned Air Ride System for 2017 Dutchmen VoltageIf your springs are worn out and flat with the measurements you referenced the Dexter axle leaf springs part # DX74XR would fit as they are a little shorter. The Lippert Center Point by Trailair Air-Ride Suspension Upgrade # LC1565391 would be a really great option as well. It will give you the 2 inches of additional lift you are wanting and also would do an excellent job cushioning the ride quality of the trailer as well.
view full answer... - Replacement Leaf Springs for 2022 Grand Design Trailer With 7,000 Pound AxleFor a replacement leaf spring you need to know your axle capacity as well as the length of your current leaf springs. You will need to measure from center of one eye to center of other eye on your leaf spring that isn't broken. Since these are fairly new there probably isn't much sag but if the leaf spring is flat you will need to account for that. Also, you want to replace the leaf springs in pairs. For example, if you found that the leaf springs measured 24-7/8" long you could use the...

- Adding Height to Suspension of 2005 Haulmark Transport DLX with 7k AxlesTake a look at the leaf springs of the trailer. If they look flat instead of bowed up on the ends that would indicate that they are worn out and replacing them would restore lost height. We only have one leaf spring with more than the 7k axle rating you have now with the Dexter Leaf Spring part # DX74XR which is for a 8k axle and is 24-7/8 inches in length. Otherwise an over under kit part # K71-385-00 would give you a lift of 3 inches plus the thickness of the leaf spring pack your trailer...

view full answer... - Availability of Higher Rated Leaf Spring for Trailer Axle that is 7kIt seems like it wouldn't be a terrible idea to go with a higher rated leaf spring on your trailer. To pick that out that I would need to know the length of your current spring unless you were willing to move hangers which your mechanic might be open to. The only higher rated spring we have than 7k is the 8k part # DX74XR which is 24-7/8 inches long. The correct MORryde SRE4000 would depend on the wheelbase of your trailer. We have the # MR47ZR which is for 35 inch wheelbases and part...

To pick out replacement leaf springs I would need to know the length of your current springs so that I can match that with what we carry and I would need to know the width and height of your current equalizers. You should note that in the 7k and 8k axle springs we only have options that are 24-7/8 inches long like the part # DX74XR for the 8k springs and part # e64SR for 7k. Now if the wheelbase of your RV is 35 inches you'd...

If the dimensions of your springs are the same as the part # DX74XR springs then you would not need new hangers. Worth mentioning is that even if the dimensions are different you could always cut off your current hangers and weld them back on in the correct location. Everything you mentioned would fit and work great. MorRyde Suspension upgrade kit # MR79ZR Replacement of...
