they are just shorter versions of the small brackets on the rear of the leaf springs.... in my opinion its the bast way to lift the rear up to 2" since if anything it just strengthens the leaf to frame connection and doesnt change ride quality...

 

Can make them pretty easy. Should only be about $5 in material and half hour labour from a welding shop.
I had a gmc canyon with underaxle leaf springs and I made my own lift shackles for it, worked out great.
I am a welder myself and if there was enough interest I could make a bunch of lift shackles and give everyone a great deal at cost pretty much.

 

what size tires do you plan on running? i just bought the same setup except mine has the 2.5" coil. ive got a thread called lifting my 2wd and on page 6 it shows redheadhunter21's 2.5/1.75 setup running 285/75/16's just to give you a picture.

 

these arent the same type as say a jeep would use.... they are actually replacements for the stock hardware complete with bushings installed... I bought them from summit for like 72 bucks they are the belltech ones... you could easily mod stock ones but I think these would be a bit more to replicate...

... and the front coil spacers he got from me are the 2.5" ones but they are adjustable to 2" as well...

 

ok yes I was thinking that they were just a shackle with only the leaf pack bushing.

 

i haven't had much time to update on here, but i got that brand new 600ft lbs impact wrench and it wont budge the nuts.. its getting bout 100lbs-120lbs air to it.. i tested the gun on my dads murano, and they came right off, i took the truck to local shop to get them to (loosen) them for me, and he put them back on too tight again. but he got them off with ease.. confused..

 

Bounce the trigger on your impact, don't just pull and hold. Make sure your compressor is up to speed as well. (if it starts running, wait till it stops, hit the trigger again.)

 

okay, ill try bouncing it next time around lol. ive waited on the compresser to fill before too.
