I did a lot of research on springs and ended up with GB Springs as my choice. So they turned up not packaged well and had a few scratches on them...
...A phone to GB springs and the MD of the company was in his car with a tin of paint!
...Anyway I fitted them and was not really happy as they felt too hard. next day a 2 leaf set arrived in the post! (wouldn't reccoment going for 2 leafs, but my landy is significantly lighter than a standard one!!!!)
I really, really cannot fault the after market service of this company. The quality of the springs is amazing but more importantly the ride is truly transformed. They have been coping with a sh1t load of power, and have had no signs of dropping after 1 year of me not been very kind to them!!!!
My point is this, they are not the cheapist, but why waste money on a sh1te product when you can have a good quality product built in the UK....
Oh with extended shackles they move car up about 3"....
