The biggest limit to the TTB suspension is flex, there are a few ways to overcome that but they are not cheap. If you were going to wheel hard, a solid axle swap is probably your best option up front.

I guess I could have been more specific. Most of the off-the-shelf kits really limit flex. There are mods you can do, such as softer springs etc, but then the steering starts to bind. Custom steering (either a modified K or swingset) can get costly. By the time you figure out how to get your TTB to REALLY flex (like for rock crawling) you still have a D35... It just seems like why not put the cash into a HP44 and you'll be further ahead. I don't know many guys with an SAS that wish they had gone for a flexy TTB...but I have read a ton of posts of guys with a flexy TTB wishing they had done a proper SAS.
My D35 has been good for quite some time now. I broke a shaft romping on it when the axle was still under my Ranger, which (being I was ignorant at the time) led me to a D44 swap on that back in '97. I broke 3 more shafts almost right after the swap. What finally fixed the issue for me was switching to the newer Spicer 5-760x u-joints and using full-circle retaining clips around the u-joint caps, which I now run on both my 35 and the 44 (being a little older and knowing my limits is probably helping some as well). Once past this point however, the cost of putting decent quality upgraded shafts into a 44 tends to run the same as just getting the 60 (and still wouldn't be as strong), and is why I'd just skip the 44 altogether.I guess guys that are wheeling a 44 hard are snapping shafts almost as often as the TTB 35. I guess a 60 woulkd be the best bet. How have the shafts in your B2 held up? I'm probablly gonna stick with my TTB and learn how to make it flex. It's kinda unique and that's why I don't have a Heep in the first place. Thabks for the good info. So, saving me some research, what's my best coil option to replace my Superstiff 5.5" coils? Planning on a plate bumper and winch. Sticking with the 4.0 for now but with all my gear I'll be around 5000lbs I think.
they make an 8 inch lift for the ranger i saw it awhile back its a bit pricey though (1200) so maybe SOA then 2 inch block (or new leafs)
