I see the rear leaf spacers, but what’s the front lifted by? Coil over top spacer?
Is that the extent of the lift kit?
‘23 TB
 
Do they run a diff drop for cv shaft angle?
No diff drop. Not needed for TB stock height as it was designed by the factory... It seems most folks that level up the front go with a strut kit and new upper control arms as the upper ball joint is the angle that gets funky. Either that or a complete 6" lift with proper diff drop to get 4" of lift above Trail Boss stock height. I'm running stock TB suspension with 34x11.5 tires on stock 18 wheels. I added a 1/4" spacer to give a little more room at the UCA/tire clearance and removed the mud flaps. Very happy with the performance. 🤙

1/4” wheel spacer?

I’m more versed on Colorado suspension’s than the TB. It’s all new to me.

Have you looked at the TB diff height compared to a stock 4wd silverado? I would be very surprised if GM put a lowered diff on the trail boss. I say that only because of the horrible upper arm angles and terrible tire wear on the stock tires. Not doubting you -would be cool if true, but I am looking to run 35" tires and want to ensure I account for all considerations and do it right.

I'm not quite sure what you're asking... :) But to clarify what I wrote above, TBs don't have a diff drop. Front differential location is the same from the factory on a 4x4 Silverado no matter if the truck is a TB or not. Aftermarket lifts with Diff drops are, of course, available. My point (which I may not have made well, haha!) was that if you want to lift above a simple leveling kit, IMHO, you would need to install a proper lift kit with a differential drop to keep your CV axles at a reasonable angle. (or go the long travel suspension route for tens of thousands!)

My set up works for me as follows... Stock suspension with Wildpeak 295/70r18 (34.4"x 11.6") tires on stock TB wheels, 1/4" wheel spacers, mud flaps removed (I did a $2 mud flap delete!). When I installed my bumper and winch the added weight caused the front suspension to sag 3/8" so I added 1/2"leveling plates from MotoFab on top of the struts and now the truck sits 1/2" above stock height (or 7/8" total level). I haven't had any UCA issues. I'm happy with it. 90% of my driving is on road but it does fine off road when I go thrash on it and the tires don't rub.

Best of luck with your search for bigger tires. Our trucks look way better with those wheel wells full!🤙
 
285/75r18 Goodyear Wrangler Duratracs on a stock 2020 Trail Boss LT with OE wheels. No wheel spacers installed. I have a leveling kit waiting to be installed, but haven't needed it yet. I did do a mud flap delete due to rubbing. I Sisto have a slight rub on the wheel well liner in reverse at full lock. I'm happy with the setup.
