rear leafs need help

Ok so i have the TSB rears, 5100s all the way around with fronts at .85" i like the ride and the looks, it looks just about stock with the back a little higher. the issue is when i load the bed up, the rear end still sags a lot, just like before the TSB was done. it does not bottom out as much but still sits very low. and that is with my 1985 Honda ATC 250sx 3 wheeler and some gear in the back, the trike weights 357 lbs so maybe 400# max in the bed.

i have considered getting air bags, or helper springs, i do not want an AAL because i do not want lift or rough ride all the time. i have heard that the helpers do not make the ride stiff when unloaded but also heard that they do?

i know that air bags are ideal for me but also they are not cheap, any experience with the Helper Springs? i have searched and only found a handful of threads on them, most were about how they were used for axle wrap.

thanks

 

I just installed a set of timbrens on the truck. I know that wheelers also came out with a similar product that also replaces the factory bumpstops. Will be carrying a small load this morning.. Will see how they ride and perform.

 

yeah my 4 leaf TSB is flat to almost frowning when NOT Loaded

 

help please?

 

Firestone has a decent set of air bags

 

I use the Firestone Ride-Rite air springs on my truck. I use them to raise the rear of my truck with bilsteins at 1.75" in the front, the ride is a little stiff at 15psi(unloaded). But if you're looking to match it with .85", they should be absolutely fine. My 4 leaf pack had sagged a lot from my atv, so this was my solution. If you have any specific questions, feel free to post them, or pm me. I'll help the best I can.

 

get a 2" AAL and take out the 3rd leaf toyota put in and replace it with the 2"

 

thanks guys. i think airbags is my best option but i just dont want to spend that much for occasional use, i might have to bite the bullet, i do not want an ALL because i dont want any lift or a much stiffer ride

any experiences with helper springs? i hear Hellwig is ok

 

less than a week with the timbrens, but I think they are an awesome product.

the only caviot is that they need to be setup properly... They say that you should have an inch (empty bed). I don't know if I had more or less than an inch (bed empty) cause I am not looking forward to taking off my shell just to measure.

with nothing else in the bed, I do hit a little stiffly over speed bumps.. But with some additional weight in the bed it is pretty darn awesome...

if I had it higher or lower by 1/2" I think I would be awesome loaded or unloaded...
