About how much more lug clearance can I expect from doing a drop and roll on my sled? 1990 650 SKS, thanks.
Drop and Roll Clearance
- Thread starter WyoUltra
- Start date
Depends on the kit you use. I did one on my early 90s sled and it gave me enough clearance to run 2.5" Simmon's speed cleats with room to spare. If I remember right I ended up with about 3" of clearance between the drivers and the top shaft.

What kit would you recommend? I was planning on updating the chain case with an edge one, and if money allows, do a belt drive.

It's a 1990 sled... cheapest way you can go is what I'd recommend. 
Back when I did mine there weren't additional chaincases available.
I have seen people put Gen II chaincases on the old Indy's but not Edge ones... the Edge ones are even longer than the Gen II. Your limitting factor is going to be how far you can move the bottom shaft down and still keep it in the tunnel.

Would I even need a kit? Or could I just put the chain case in, basically mount the top jack shaft, then see where my drive shaft bests fits? Then basically drill my tunnel, and also put a brace on the tunnel for added strength?
I have a gen2 chassie I'm working on right now that somebody put an edge chaincase into, the jackshaft is still in the stock location and the mainshft just ended up wherever it ended up. There is alot of room for the track in there, this one is running a CE 2.5" with room to spare. You do have to shim the chaincase off the bulkhead to clear the brake rotor so you have to do some side to side adjustments on your drivers but for a guy on a budget it works just fine. Like sledguy says it's a 1990, just have fun with it.

Kit? I've never used one. Just take lots of measurements and make darn sure you've got it all square to the bulkhead.
I vote for edge case.
Remember to keep the driveshaft as far forward as you can to prevent the nose from getting too heavy. I've rolled them too far and it makes a huge difference in how the sled handles.

Actually, I think I have a Tison extended Gen II chaincase I'd donate to the cause if you want to pay shipping. Hell, your in Casper, you down in SLC once in a while? I could meet you and give it to you.

I'll actually be in Evanston, WY next week, maybe I can pick it up?
Tuesday and Wednesday would be my best bet, otherwise I'll pay shipping.
i have an edge case in a wedge tons of clearance

Edge chain case in a wedge too. No kit, I just measured carefully. Tons of room, I can reach my whole arm in between the tunnel and my 1
