250r with +6 swingarm

[400in300]

What rear shock should i use for my r with a +6.I weigh 260 and I will be doing hill climbs with vertical 3-6 FOOT lips mostly(some drag racing) so i will be jumping some off the lip.the motor is built for low end and I love passing the banshees up hills and then launching the lip.THE HILLS I WANT TO GO UP YOU HAVE TO HAVE A EXTENDEN ARM THAT IS WHY I GOT THE +6.:devil

i would say definately an aftermarket. I would call up works and get them set up for u. justdescribe what u do. they should be able to help u
