What Is A Slipper Spring? Slipper Spring Suspension
Slipper springs have an eye on the front of the spring and an arched open end on the rear, allowing the spring to “slip” on the equalizer or rear hanger.
Do you grease slipper springs? Re: Slipper spring question
What is a double eye spring? Double eye leaf springs are identifiable by the two closed ‘eyes’ on either end of the spring. All available springs measure 1 ¾” in width and comes with a 9/16” inner dimension nylon bushing already in both eyes.
How do I choose a leaf spring for my trailer? Trailer leaf springs need to be selected based on the axle weight rating, as well as on the spring type (slipper or double-eye), length and width dimensions. Axles usually have a sticker or plate on them that provides their weight rating. It is important to note a few things about replacement springs.

Are torsion axles better than spring?
Torsion trailer axles offer a smoother ride and less maintenance. Leaf springs are more durable, less expensive and far easier to replace parts on. Whichever you choose, you’ll see the best results by properly loading your trailer with the aim of getting the most wear out of the system you pick.
How do I know if my trailer springs need replacing?
Trailer springs should always be inspected for cracks and breakage to avoid failure of the trailer spring. Cracks typically appear near the philister bolt and near the eye of the bolt that connects your spring to your hanger. Anytime you see a crack or break in the spring it is time to replace them.
When should I replace my trailer leaf springs?
A leaf spring should be replaced if it is badly rusted, has cracks or breaks in its leaves or if it is sagging. A 14-year-old travel trailer could certainly be in need of new leaf springs. The keys to selecting correct replacement leaf springs are to match your axle capacity, number of leaves and spring size.
How do double-eye leaf springs work?
Double-eye leaf springs have an “eye,” or bolt hole, at the end of each spring. The steel spring rolls into a curl at the end, making a circle and attaching to the suspension bolts at either end of the spring. (This is one way double-eye springs differ from slipper springs.
What is a slipper spring on a trailer?
Slipper springs. Simple and long wearing, slipper springs have an eye on one end, while at the other end the open leaves form a ‘tail’ that slides in a hanger welded to the trailer chassis.
What is a leaf spring shackle?
A shackle is an integral component of the suspension system that attaches between the leaf spring and the vehicle frame. It allows for the leaf spring to work through length changes during suspension articulation. The leaf packs, or leaf springs, position and center the axle under the vehicle.
How do I choose a leaf spring rate?
The equation below can be used to estimate the spring rate of a given leaf spring pack:
Spring Rate = (E x (2+nfull/ntot) x ntot x w x t3) / (0.75 x l3)
ntot = total number of leaves.
Spring Rate = (G x d4) / (8 x n x D3)
G = Shear modulus (11,385,500)
Spring Rate = (Upper coil rate x Lower coil rate) /

Are parabolic springs good?
BENEFITS of a parabolic leaf spring over a standard semi-elliptic: lighter unsprung weight; tapering of each leaf returns load-carrying ability combined with improved ride quality both loaded and unladen; interleaf friction is (largely) eliminated given the leaves don’t touch each other; improved ride qualities and
How are leaf springs rated?
Expert Reply: Leaf springs typically have the part # stamped on the strap that holds the leafs together at one end of the shorter leafs, or it is painted on the concave side of the springs. If you have a 3,500 lb capacity axle the springs should be rated for 1,750 lbs each.
What’s better torsion bar or leaf springs?
Torsion axles are mounted directly to the frame which means fewer moving parts compared to spring suspensions, resulting in a smoother shock action. This stiffens the frame, reducing flex. Leaf springs better absorb the load from uneven ground or shock from a pothole. Each tire has its own set of springs.
Can you flip a torsion axle?
Subject: RE: Flipping torsion axles
Do torsion axles wear out?
Helpful Expert Reply: It is certainly possible for any axle to wear out enough over time to need replacing. Since the suspension is built into a torsion axle if the suspension part was to wear out pretty much the only solution would be to replace the axle.
How much does it cost to replace a leaf spring?
How Much Do New Leaf Springs Cost
Should leaf springs be lubricated?
The springs should be kept fairly clean in order to extend their useful life. Modern leaf springs do not need lubricating with oil — which may damage any anti-friction material between leaves. Spray them instead with a silicone-based lubricant.
How long do leaf springs last?
about 200,000 miles
On average a set of leaf springs for a standard pickup truck or van will have a lifespan of about 200,000 miles. This number is not written in stone, and some vehicles will break their springs with far less than 200,000 miles on them while others will go well beyond the 200,000 mile mark before they break.
How do I know if my leaf springs are bad?
Look out for these tell tale signs that you need to replace your leaf springs:
Squeaky sounds while your truck is in motion.
Slouching on one side.
Sagging in the back.
Diminished handling.
Trouble hauling and towing loads.
Suspension bottoming out.
Cracks on leaves.
What is the main leaf spring?
For the latter, the front end is attached to the frame while the other end is attached to a short swinging arm through a shackle. The main function of leaf springs is to provide comfort to the passengers by minimizing the vertical vibration caused by the nonuniformity of road geometry.
