Truck lift - Your opinion is wanted!

[HippoNZ]

Hi guys
update for you all, I now have some dosh to spend and wanted to know this,
will this kit be suitable short term until I can replace more parts
4" springs
4" shocks
steering damper
drop boxes
panhard rods
longer brake lines

Will this be ok and enough to stop the rear tailshaft from slipping at the yoke - as quoted by beneboy "ooo and dont forget your drive shaft with a shorty and depending on the amount of flex it may separate at the slip yoke"? will the drop box be ok to sort this issue.
Times are getting serious lol cant wait!

Drop boxes won't help the rear driveshaft. Fit the suspension and flex the car up on a travel ramp or similar and check the driveshaft extension, you may need a rear tailshaft spacer if it's over extending. Rear driveshaft angles will probably also be an issue being a shorty, you will most likely need the tail shaft modified to fit a double carden joint.

Diff breathers will need to be extended and you will need an extension bar for the brake bias valve.

Thanks tony, after some researching I've found out what you mean lol so normal driving wont affect it, just when i start to flex a bit I could run into trouble with the rear shaft falling out? are double carden joints expensive?

[YNOT]

Rear tailshaft length will be OK (after the lift) for normal driving but you will probably have driveline vibrations because of the angle - that's what the double carden joint will fix. I have no idea of price to get the tailshaft modified, you will need to talk to a driveshaft specialist.
At least you can keep driving around while the rear shaft is out getting modded, just put it in 4WD, lock the hubs and run around front wheel drive!

what the difference between caster corrector bushes and a dropbox? and do I need both?

what the difference between caster corrector bushes and a dropbox? and do I need both?

Castor correction bushes are limited to about 2 degrees of castor correction, OK for a 2" lift but not nearly enough for a 4" lift. They work by twisting the front diff back to compensate for the forward twist caused by the lift. Correction bushes do not correct the alignment of the radius arm which will be in a droop position after the lift putting stress on the rear mounting bush.

Drop arms replace the original radius arms and are shaped to put the front diff back in correct alignment as well as keeping the main part of the arm in the original (horizontal) position taking stress off the rear bushes. Most drop arms also move the front diff forward about 13mm as well.

Drop boxes relocate the rear mount of the radius arms approximately 90mm (depending on what drop boxes you get) below the original mounting point which puts the radius arms and therefore the diff back close to correct alignment. Most drop boxes also move the mount forward about 12mm as well. giving better wheel arch clearance for bigger tyres.
