Re: Heavy duty springs SAGGING
This is the first time in my 10 years of being here to here of this kind of problem with the HD springs.
Did you change the stock rear spring shackles? Are the bushings in the rear shackle where it mounts to the frame bad/gone? Need a pic of the springs with the weight on the back |

Re: Heavy duty springs SAGGING
Not certain, but the springs almost look too long. Based on the angle of the rear shackles. Can you measure them unloaded and compare to the originals?

Re: Heavy duty springs SAGGING
I'm going to act like I know something about this, which I doubt, but I seem to recall an old pickup of mine many years back doing the same thing.
After some rear end work, i tightened the u-bolts to the spring with the truck lowered slightly with the wheels on the ground. The spring had a negative bow as yours does. Try loosening the u-bolts on both sides and jack up the Frame only and let the wheels hang off the ground. Then tighten the u-bolts evenly. The individual spring leaves should correct the upward arc. It might be worth a try even if I'm wrong here! Good luck! Last edited by Tom47; 02-12-2019 at 09:20 PM.. Reason: Added wheels on ground. |

Re: Heavy duty springs SAGGING
This is a long thread but I think it will give you some insite.
http://www.buggiesgonewild.com/elect...precedent.html What I learned from this is longer shackles will give the springs more arc. Also he could not find shorter springs. |

Re: Heavy duty springs SAGGING
Do Precedents have a front and rear to the direction of the leaf? Could they be in backwards?

Re: Heavy duty springs SAGGING
Those were either severely overloaded or they were not properly heat treated to retain their shape. Those have inverted, which usually means the springs are worn out, but since those are fairly new I would think they’re just plain defective.
I also notice you appear to have no rear shocks on the cart. I know a lot of people here say they’re not needed with the HD springs, but not having rear shocks can allow the rear springs to compress more than they should when hitting bumps in the road, and that can lead to spring damage due to inversion. It overworks the spring and leads to early fatigue. If the original shocks are too short I would recommend you find longer shocks or use extensions so you can put the shocks back on. As the spring arc compresses the shackles move out because the spring gets longer. If those springs were not totally flat the shackle would look normal. There is almost always some rearward angle to the shackle (or forward angle if on a front axle) in a properly setup leaf suspension. This is to prevent the spring from binding against the movement of the shackle as the spring moves from the no load position into a loaded position. |

Also as to the portion about dips bumps and holes in the road, my neighborhood is smooth asphault. I guess I will be contacting Golf Cart King directly as it is past time for an Amazon complaint. |

Re: Heavy duty springs SAGGING
UPDATE: Ok so after emailing and a phone call with Golf Cart King the tech said that these for sure are a defective set of HD Spring and they are going to be sending me out a new set of springs. they said that it is very rare to have a set do like this even if they were put to extreme abuse loads. CASEY was very helpful and the GCK customer service was great to deal with.
Hope that this information and picture can be of some future help to anyone having a similar issue. |
