Inverting overload/restraining leafspring

[nansky]

I have seen some AUV's especially Mits Adventures have modified/inverted
overload/restraining leafspring for the purpose of softening suspension feel.
I tried it with my ride - Isuzo Hilander which has basically the same platform with Crosswinds and Sportivos. It really improved ride comfort especially
for passengers at the back seats. Am I compromising safety over compfort?

I did this with my pick-up and theres no problem with it.

Unless you're really carrying loads to the limit of what is suggested for your car, you're not compromising safety. If you have reservations on carrying heavy loads then you can compensate a bit by adding gas shocks which are stiffer then the stock fluids.

You are just lowering the load limit. But not safety in general. A full load of passengers would still not be a problem since your vehicle is designed to take much more than that.

Tnx for the replies. I'm now confident with the safety issues of my ride after
the modification.

Sir Nansky,

How many leafsprings did you invert on each side? Or did you just invert the shortest one?

Thanks.

Thanks.

The shortest and thickest leaf otherwise known as the overload/restraining leaf was inverted on each side. It really softens the ride, less tagtag as felt by my regular passengers. More importantly, kung nag-iisa lang ako, hindi ako tagtag.

However, as a protective measure, I put rubber snubber on each tip of the overload spring to support added weight when the car is full of passengers.

Where can I have this done? And where do I get that rubber bushing?

It can be a DIY job but you can visit any underchasis specialist shops for proper torquing of U bolts.

Rubber snubbers (4 pcs) were fabricated in our local bushing shops. I cost me 20 Pesos each.

If you intend to proceed with protective measure (optional), ask the mechanic to drill a hole (through machine shop or acetelyne) in both ends of the overload leaf for you to fit the rubber snubber in both ends leaving at least 1/2 inch space between the overload leaf and the succeeding leaf for free play during light load.

Please visit below site to visualize rubber snubber.

I had mine done at Wheelers Susp. Haus in Banawe before. Most general talyers and underchassis shops should be able to do the job.

Tutal punta ako sa Cruven bukas. Tanong ko kung ginagawa nila ang inverted leafspring.
