One of the reasons most of the team are now running the Big bore shocks from the 22 on our XX4's (and XXX4's) is because it's thus a common set of springs, pistons and spares that we carry to each meeting. Nothing more sinister than that.
However they do work well, look good (which is important
) but as to whether or not its a transformation I don't know.
However, if it's something that interests you, the set up we're mainly running is 4 hole 55 pistons in the front with 27.5Wt - 30Wt and Green springs and 4 hole 54's in the rear with 27.5wt and Pink or Yellow springs.
Magic setup? Don't know - but you'll need 4mm limiters under the front piston andwe're using a 22 ball cup (cut 3mm) on the rear with a ball stud in the wishbone so that the spring cup can clear the wishbone. Some have reamed the inside of the spring retainer to allow it to drop a bit further down and relax the spring a touch more.
Oh - and bleeder caps / emulsion style damping of course along with rounding the edges of the pistons as per normal
Hope this helps
