The only real difference between your current 3-leaf springs and the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 will be the thickness of the leaf spring stack. This will be 3/8" thicker when compared to what you have now. It may be possible that with the additional material and thickness they will hold up a little better and last longer. Overall though, they have the same capacity regardless of the number of leaves. view full answer...
With the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # e78SR and 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # e34SR both being rated for 6,000lbs there won't be a noticeable difference in height. view full answer...
The number of leafs on the spring doesn't affect the durability or strength of the leaf spring, so there really isn't a difference between the 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long # e27SR and the 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 25-1/4" Long # e57SR in that respect. There is a difference in the height of the spring stack and the length, which is where you would want to focus when choosing the correct replacement springs for your trailer.

The reason why changing from a 4-leaf double-eye springs, like part # e47SR, to a 5-leaf double-eye spring of the same capacity, like part # e34SR, won't matter in a situation like what you have is because it's all about the strength of the leaf spring itself. The extra layers will add height to your trailer but they have the same weight capacity so the extra layers don't add any extra security.
If you're having problems with the leaf springs holding up then there are a few things you... view full answer...
The only difference between a 4 leaf spring and a 5 leaf spring like the # e34SR is that the 4 leaf spring will use slightly thicker leaves and is 1/8 of an inch shorter. To get the best measurement of your existing springs, measure the center eye to center eye width with the trailer up on jack stands with the axles hanging free. Leaf springs should be replaced in pairs. view full answer...
The difference is found in the application. The Slipper Spring styles, like part # SP-179275, are intended for use with more heavy duty applications, while the Double Eye styles, like part # e77SR are used to provide a more comfortable ride.
The part # e77SR that you referenced will be the correct fit if your current leaf springs are 26 inches long from the center of the attachments points (usually known as eye-center-to-eye-center).
You might also still be needing a U-Bolt mounting... view full answer...
The 4-Leaf Double-Eye Spring for 6,000-lb Trailer Axles part # e47SR for all intents and purposes is the same as the SP-221275. They are the same size and capacity, just made by different manufactures but both quality options. view full answer...
The etrailer 4-Leaf Double-Eye Spring # e97SR is going to have the same dimensions as the Universal Group # SP-210275. Both springs are rated for a 3,500lb axle with center eye to center eye measurements of 27". They both are made of 4 leaves and have 3/8" thick leaves. The only difference is in the manufacturer of the product. view full answer...
There really is not any type of quality difference between the two slipper springs:
- 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # e99SR & # SP-178275
They both have the same measurements, steel construction, and nylon bushing in the spring eye. I'd honestly go with the least expensive option to save yourself some money. Also, I do recommend new bolts when mounting springs, the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079. view full answer...
An Add-A-Leaf kit differs from the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS34FR for your 2001 Toyota Tundra in that the Add-A-Leaf is literally just adding another leaf spring to your spring stack to help make it a little more robust where the RAS system is a little more "smart".
It has a spring that helps to provide constant tension and you can adjust it some for more of a relaxed or stiffer ride quality. So instead of just making your leaf spring stack thicker... view full answer...
Yes, slipper spring # e33SR is the same as Universal Group part UNA-264. This is considered an open slipper spring. I he also included a link to our help article on slipper spring suspension for you. view full answer...
Yes, you can use two of the Correct Track Trailer Alignment and Lift Kit - Single Axle # LC87120 and it will be the same as the tandem axle kit # RR23QX. The tandem axle kit comes with 8 suspension plates and 16 alignment correction plates along with the hardware. Since the # LC87120 has 4 suspension plates and 8 alignment correction plates it would be the same if you ordered two.
For leaf springs, you will want to make sure you match the current capacity and length. The length is measured... view full answer...
I personally would not have any reservations about using a torsion axle. Dexter is a leader in the industry but Hayes/AL-KO are quality as well. It seems to be easier to get parts for Dexter axles and they tend to cost less.
On a torsion axle you will want to be cautious not to overload it (of course this goes with leaf spring axles too). The suspension components on leaf spring axles are easier to replace as well but a torsion axle is going to give you good performance provided you keep... view full answer...
The main difference between air bags like the Firestone Ride-Rite Air Helper Springs part # F35FV and add-a-leaf like the SuperSprings Custom Suspension Stabilizer part # SSA22 is that the air bags can be adjusted to a particular trailer or load and the add-a-leaf options are not adjustable. That said, they are both great options for a 2020 Ford F-250 Super Duty.
The Titan Chain Alloy Snow Tire Chains part # TC2533 fit both 275/70-18 and 285/65-18 tires. view full answer...
First of all, great choice for suspension enhancement for your 2018 Ford F-150 2WD as the RoadActive Suspension is an exceptional system. In regards to the correct version, it really comes down to how much sag you get:
- Less Than 2 Inches of Sag: RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-B
- More than 2 Inches of Sag: RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty # RAS94FR
It doesn't have to be exactly 2 inches of course; if you're getting... view full answer...
Both slipper springs and double eye springs will work just as well as the other as long as they are rated for the weight of the trailer. Typically slipper springs are seen more on the heavier capacity trailers.
The issue you are having would not have anything to do with your leaf spring style. You either have worn out suspension components on your trailer or the axle/spindle/hub has serious problems that need to be addressed. I would recommend you either examine everything I just mentioned... view full answer...
That's a good question, and the answer is pretty straightforward - yes, the RoadActive Suspension (RAS) is going to give you a smoother, less bumpy ride than the Timbrens for your 2019 Toyota Tacoma. Like you mentioned, the Timbrens do their job well due to the stiffness of their rubber springs, but that stiffness can also cause the ride to be uncomfortable or even jarring as there isn't much give to them. The RAS will absolutely remedy that while providing the same - or better - enhancement... view full answer...
Since you will be towing a travel trailer, which is a static load that does not change weights all of the time, I recommend going with leaf springs, see link. If you have a 2 wheel drive model that is not a Pre-Runner, go with # SSA1 for 2,000 pound capacity or # SSA7 for 3,000 pound capacity.
For a 2 wheel drive Pre-Runner OR a 4 wheel drive model that is not a Pre-Runner, go with # SSA19.
Air springs are great if you will be carrying varying load sizes and types so that you can level... view full answer...
You are correct that there are two RoadActive Suspension Leaf Spring Enhancement Kits for your 2017 Toyota Tundra, the # RAS34FR which has a 3000lb capacity and the # RAS4611TD with a 2000lb capacity.
Between these two kits I recommend going with the # RAS34FR as it will give the most support to your suspension. These kits will not negatively affect your unloaded ride so there is not a down side in going with the heavier duty system.
With the # RAS34FR you will not only get less squatting,... view full answer...
With square axles, neither of our over/under kits will be a fit to raise the height of the trailer so another option is to use longer hangers for the leaf springs. You will just want to confirm the hangar height.
You may be able to use a hanger like part # E4139. This hanger is designed for double-eye springs and is 4-1/4 inches tall. The old hangers will need to be cut off and the replacement hangers welded on by a professional. view full answer...
