Default Power steering hose

I've lost 4 high pressure hoses in 3 years. I lost one today in the second session at Pocono with a Diablo on my azz. (I couldn't pull him but he couldn't pass me either on the straights ) But had to let him go by once my steering started to fail. The hose failed again at the fitting that goes into the pump. The last 2 did the same. The last 2 were GM hose kits.

I e-mailed DRM to see if they still have a better hose they used to sell. Has anyone ever used it? Any idea on price, modifications? How do you guys that track your cars make the hose survive?

At least I got to take my buddys 96CE out I modded to 400hp, and my other buddys 02 ZO6 to beat a few more Ferrari and others. Working on all my buddys cars mean a have a bunch of back up cars. I had about 6 there to choose from. What a great bunch of good friends

its just a a thought but,maybe some underdrive pulleys would help out by lowering the speed of the power steering pump?

How's about a custom mfg hose made from braided hose and A/N fittings? Or if you know someone in the aerospace industry, hose with MS permaswage fittings. These hoses are made with a 5k psi minimum burst pressure and MS fittings WILL NOT leak (unless they are damaged).

It's not the rubber hose it's the metal fitting right off the pump that cracks from the stress of autox/road race events.

Same experience here - went to the DRM stainless braided hose kit and haven't had a problem since. The SS hose is a bit of a PITA to get installed but worth every minute. The hose does not take kindly to being twisted / bent into the tight radius that is needed for installation but believe me, it can be done and lives quite nicely during track events. I've had mine installed for over a year and haven't seen any evidence of leakage - several track events and everything is dry. I don't think you'd be disappointed with your results.

I have had the same problem with my LT4 and it really sucks when you get that spray of powersteering fluid across the inside of the hood during a track day. It happened about 5 times to me the first few years I was doing track days.

My solution has been to use a NAPA Pressure hose and just replace them after 500 track miles as a preventive measure. I also use Redline PS fluid now. No more problems, and with a little practice it is fairly quick to change the hose.

Cheers,

Lawrence

Yes, But the fittings for the hose would be stainless steel.

Mine is doing this too as we speak. That little hose is an expensive part too! 88 bucks from GMpartsdirect!


How much for the DRM?

I run the hose after loosing several GM units.

Works as advertised-no more issues.

Cost me $125 a few years ago for part number 31 120.

Just called in my order to DRM. They said it was a full kit with aero fittings etc. Grand total was 99 bucks plus shipping.

He said it would go out tomorrow.
