when did they go to Hydroboost
What year did they go to Hydroboost? our 97 3500 4x4 has hydroboost but someone i know has a 96 3500 2wd and it has no hydroboost.
i need to get all the hydroboost lines for a 97 so i was wondering what year range i need to look for here.
thanks

sweet. i also read somewhere 97 is 1 year only because the threads are SAE and 98+ hydroboost is metric? so i need 1 year only stuff. cool

97 is first year for hydro boost... a step backwards if you ask me.
my old 97 12v had non-stop power steering pump and leak problems.
went thru 3x pumps and had a devil of a time stopping all the leaks.
when pump goes out... not only do you loose your power steering,
brakes also goes out.... not a good situation!!!
my 96 12v has been all but trouble free... vacuum boost brakes. works like a champ with zero problems.

I have not had any issues with either of mine except one PS hose rusted a pinhole.
I see more people here with Vacuum issues than hydraboost issues.
To each his own I guess.

If the power steering pump fails on a vehicle with hydroboost, there is a canistor of compressed gas (nitrogen if I recall correctly) on the hydroboost assembly that provides enough pressure to stop the vehicle using the service brakes.
If vacuum pump fails or the vacuum system develops a significant leak on a vehicle with vacuum assisted brakes, the brake system will become ineffective after a few applications as well.

having owned both with and without hydroboost...
my opinion is very little difference in braking power.
don't get me wrong... not saying all folks with hydroboost will have problems.... just that mine had loads of problems due to excessive pump failures.... believe me... worrying about losing your brakes and steering is not fun.
vs I've had zero problems with vacuum pump on my 96 12v and 97 12v. as a matter of fact... out of all the vehicles I've ever driven with vacuum assisted brakes.... have NEVER had a vacuum boost failure. have had numerous brake failures due to brake hydraulics and hydroboost failure.
used to be in the auto parts business and have seen more than my fair share of parts failures. in ten years I sold one vacuum booster vs sold a butt load of brake hydraulic parts and power steering pumps.
all I can do is relate my personal experiences

Sorry to hear of your bad luck, but I could not disagree with your opinion more. I consider hydroboost to be a huge improvement over vacuum assisted brakes as it provides consideraby more line pressure and braking ability. The hydroboost system on my 97 has been utterly reliable and trouble free.
If the power steering pump fails on a vehicle with hydroboost, there is a canistor of compressed gas (nitrogen if I recall correctly) on the hydroboost assembly that provides enough pressure to stop the vehicle using the service brakes.

Reason the switch to hydroboost came about was concern about liability if oil got in the system and destroyed components including the booster.
There was even a recall to install a check valve to try and eliminate oil intrusion but it didn't always work. The recall even replaced the entire vacuum system if it was contaminated and came with a seven year warranty.
Very expensive for Chrysler.
Dodge was just covering their butt by making the switch.

chevy has been running hydroboost for a long time and i have never had any major issues with any truck i have driven with it. As far as braking the hydryboost is far superior to any vacuum braking system

sorry but gotta disagree...
don't get me wrong, not saying anything is wrong with hydroboost.
vacuum boost brakes are used all over the world.
vacuum boost are way more common than hydroboost.
both systems are able to put out enough pressures to brake.
each system has it's weaknesses and advantages.
both are very reliable...
just that mine had all sorts of problems due to repeated hydraulic pump failures and leaks in system. so I got up and close to hydroboost's weaknesses. which is if pump should go out... you will lose assist to both power steering and brakes at the same time.
vs if you lose your vacuum pump ... you will loose your brake assist only. just like loosing your brake assist shortly after motor dies in a gas vehicle and vacuum reservoir is used up.
