Report on the slam kit:
Bike rides fine, handles well in turns, lower center of gravity, easier to hold up, no floorboard grinding even in tight turns. (I went pretty low too.) Bumps felt fine, seemed like the shock compressed a bit more.
On my "03 (lowered front and rear) I got used to it feeling like it hit the bottom travel point and it could be jarring. Current bike with the stock ultra shock it felt fine and I had to hit a big short sharp dip for me to even feel the difference from unlowered. Bumpy railroad tracks felt fine.
I like the feel of lower center of gravity, it feels more controllable in turns and stops. I'm amazed that I felt so much of a difference from one inch of lowering.
All in all I am happy with this lowering kit. I would like to hear from more who try this as far as how it worked out on their bikes.
Rider, oh man you were right I LOVE the J&S jack! This thing is rock solid and I easily rotated my bike for a faster exit. Moves around like it's floating. A little push/pull on the engine guard is all it takes. ZERO sway or flex. Oh yeah if your garage floor is not perfectly level it will start to roll on it's own. Screw down the rubber tipped stop feet since just leaning on it could send it across the garage. Best jack I ever had. Makes the cheapo "red" jacks seem like toys.
Sledge
I've been using the Pitbull Lift for seven years and feel the same way. Rock solid! But, if I'm doing a lot of maintenance, tires, engine and will be having to torque bolts, I still feel more comfortable using straps to secure it to the lift. Just one on each side. Mostly it's just a mental thing, because if an 800 lb plus piece of machinery loses balance, it's coming down. Then it would be best to just get outta the way. The real trick for best stability is finding the sweet spot where it is perfectly balanced from front to back. Once there, it's not going anywhere.
My neighbor is ordering the J&S because it's a hundred bucks less. So we'll be able to do a nuts and bolts comparison. From what I've read, I believe they're pretty close in quality and construction.
I like the lowering project...nice! Thanks for the play-by-play. Well done. By the way, I have the Brukus Saddle Bag Secure bolts on my Ultra - a great investment for a little peace of mind.
