I have both of our HUMMERs (H3 & H3T) @ 23 1/2". The H3 has the stock adventure shocks with the HUNNER 1/2" nut modification to the shocks and the stock "bump stops"(progressive dampeners) the H3T has Bilstein Cognitos and the 1/2" TrailDuty bump stops (not progressive dampeners). The H3 wiout the extended "bump stops" has about 1/2 or a little less space between the LCA and the "stop", the H3T with the extended stops has ZERO space between the LCA and the stop. I acutally prefer the OnRoad and OffRoad ride in the H3 to the H3T so we are going to put the stock progressive dampeners back on and see if the ride close to the H3 or better...... So I'm prob. not the one to ask.

 

so is it safe to drive around for a little while with the t-bars cranked without the new extended bump stops installed? Or should I order the bump stops first then do it all at once? thanks

 

ahh screw it, next paycheck im just going to order this kit Trail Duty Bilstein Hummer H3 Front Leveling Kit is this what most of you guys bought when u adjusted your stock keys?

 

Good post Tainter.....anyone needing the stops can be found here or also on e-bay

Trail Duty Hummer H3 Extended Front Bump Stops

 

you can safely drive without the extended bumpstops but the nose diving at every stop sign and red light will drive you crazy. the trail duty kit is the way to go it is well worth the money. To me the ride is alot better then when the H3 was stock.

 

I've been driving with the T Bar lift and stock bumpstops for more than 3 years. That nose dive so many complain about is called suspension "travel", and I will always prefer to have as much of it as possible.

Sorry, but I'm not going to use a bumpstop to limit it.

 

How hard is it to change the bump stops?

 

good question

 

Not hard at all.
Jack up the truck enough to get the upper arm away from the bumpstop so you have room to work. It's much easier if the tire is removed but not mandatory.
Pry the old one out of the metal cup with a large screwdriver. It is held in by 3 or 4 barbs.
Lube up the new one with something like liquid dishwashing soap and wiggle it into the metal cup. Then rinse off the excess soap. Should take all of about 5 minutes each side.

Only use soap as the lube, NOT any type of grease or oil. You need to be able to rinse away the lube when you are done !!!

 

great info thanks Bunger...
