Lifting a pup - troubleshooting

Post by OK! »

I’m in the process of raising my 82 p’up and reinforcing the suspension in the rear to hold up a camper, square tube rack and roofnest pop up tent.

So far I have installed bigger tires and new shocks.

I have cranked the torsion bars all the way up and the front end has lifted up a couple inches. I am going to fabricate a longer shackle for rear-end lift. To stiffen and accommodate the rear I plan to either get new leaf springs or add-a-leaf.

My questions are: will this leaf kit work with an 82 pup?
http://www.calmini.com/detail.php?b=3&m=10&t=2&p=928&n=

Will re-indexing the torsion bars provide more lift? In addition to that, should I also buy some new extended control arms to properly lift the front end? Calmini has some for 84 trooper as well.

Detailed pics coming soon.
Thanks guys

UPDATE!
Figured the rear lift out. Lots of free time with the virus...

Got an add-a-leaf from SD truck springs.
https://www.sdtrucksprings.com/index.php?main_page=product_info&products_id=31448

Hard work but ended up lifting the rear end a few inches!

Add a leaf installed at bottom of leaf stack.

Done!
Done!


For reference...my stock truck U-bolts had enough purchase left to install the add a leaf. I did not have to find new u-bolts. $50 for a 2.5” lift, not bad

Stay home and be safe every body!

Thanks for the information. I tried lifting my 1983 P'up diesel 4x4 by installing longer shackles but ran into a nasty shimmy in first gear. The driveshaft had just been rebuilt with new u-joints and center bearing so I felt confident it wasn't the issue. I re-installed the stock shackles and the shimmy stopped.

I tried the link you included but the website appears to be down. Do you remember the brand and part number of the add-leaf you purchased? Thanks!

U bolts should always be replaced.

Never ever ever re-use them. I don't believe isuzu says to replace them in this application, but I would never chance it. Especially when they are 40 years old

Link works on my end. Try just going to sdtrucksprings.com, and finding the drop down menu for Isuzu pup 82-84 and find the add-a-leaf kit, should only cost about 40-50 bucks for both sides. The part number it says is 13120 but that appears to be the same number for many other add a leaf kits. Anyway, the one I got was labeled “1975-1998 Chevy/GMC LUV Pickup, S10 Blazer - Pro Comp Add-A-Leaf Kit (1.5"-2.5" REAR Lift) [Pair - Short Leaf]”

Be prepared to cut the centering pin down to length and all that. You might have to unhook your hydraulic brake cable mount temporarily too. Good luck! It gave my truck quite a bit of lift. I was surprised

Thanks for the heads up, I’ll order some right now (truck is currently out of commission due to clutch issue anyway). I’m new to all this and did not know that !

Thanks for the info and tips on the centering pin. I was able to open the link with the Chrome browser so apparently sdtrucksprings.com doesn't like the Opera browser I normally use.

Thanks for all the info. If I already have 2” lift shackles installed and then do the add a leaf, will it give me additional lift or am I already topped out?
