H3 Repacked Rear Leaf For Heavy Load Carrying On H3

[ChihuahuaRide]

Originally I had already got an upgrade for 2" lift with extended aftermarket rear leaf shackle plus added an additional leaf from Tough Country which makes up a 5/1 leaf spring pack setup, but after extended duration of used carrying loads with heavy off-roading the 1st leaf started to sagged at the front mounting ear bend and I decided to cut and safe the 1st main OEM leaf ears off and stack additional 2 leafs of Toyota HJZ 75 1st leaf as my 1st and 2nd leaf on my repacked leaf spring pack that now is 7/1 setup which by calculation should be able to carry 380kg constant load without sagging problem in future. Have anyone tried this setup before ? I will post the outcome of this upgrade once I get the repacked leaf spring pack try out on an upcoming offroad trip this weekend.

Interested to hear how it rides - on & off road.

I haven't tried exactly that, but I did re-arch my leafs and added one full leaf at that time. It holds the weight much better now. But it is stiffer and needs at least 50-100 lbs in the cargo area to soften the ride on the street.

The repacked springs project is still ongoing as had to rework the Schwarttzy high clearance leaf springs mount bracket with some additional rib support weld on the bracket to be able to take the repacked leaf spring pack. Will make some photo available to be uploaded for referral next week.

Hey got a part number on that sexy, blue, poly-u spring bushing?

The repacked rear leaf spring ride on the road was better then expected as I tried driving thru a stretch of road with speed breaker bumps at 50km/h the rear has been solid did not bounce around which I was expecting at bit without load. The rack angle of the H3 has also improved with my front torsion bar already being crank to the maximum safe limits of 23 1/4" + 1" body lift in place. The rear came up an additional 1 3/4" from the lifted 3" after this repacked leaf spring mod with the vehicle having any rear load in place. Will be going to a 3 days medium difficulty offroad trip next week to try out this setup and will have report on this to all.

The bushing are actually for Toyota HJZ 75 rear leaf springs PU bushing made in Malaysia and I burn out the rubber bushing on the original to get the bolt steel collar and press fit it to fit the PU Bushing and need to trim the side walk of the PU bushing thickness with a sand paper grinding dish to get the accurate width to fit the rear shackle and I used new OEM rubber mount bushing on the front of the leaf spring mount to reduce the squeaking sound that normally happen with a PU Bushing fitting tighten up. I will get you a part number for the bushing made by SuperPro Australia on this in my next reply to you.

The repacked leaf spring packed stood very well under load of 300Kg at the rear and the ride during off-road drive was super flexible for a 7/1 setup.

The side bar as we call it locally is s customs one off made by my buddy which runs a fabrication shop for 4x4 vehicles locally in my area. So far had a few close calls passing thru wall slope area with bar in between the cabin and wall !
