Power steering on a ls swap

Seems every ls swapped vehicle I see at car shows and cruises does not have power steering. Is it hard to mount the power steering pump from the ls to the original steering box. I’m looking more and more into doing the 5.3 in my 70 but am afraid I’m going to run into problems like this.

Re: Power steering on a ls swap

I must see every car you don't see. Almost every LS swap I see has power steering.

There are many ways to address the issue with the lines, custom made hoses, adapters, AN lines etc.

Re: Power steering on a ls swap

Many LS swappers run into pump to steering box clearance issues with truck based engines. The problem is solved by installing a smaller diameter pump pulley from a mid-nineties V6 Camaro.

I guess I read the question wrong.

So, yes a smaller pulley as mentioned above or some of the aftermarket accessory drive systems.

X2.
That's what i used on my swap with a Truck LS.
And if you already did the Jeep GC steering box upgrade, the hoses thread right in to the box.

Re: Power steering on a ls swap

Installed a Silverado 5.3L into a '67 Camaro which require accessory relocation brackets due to the narrow subframe.
Truck PS pump fit fine and plumbed right up to the OEM Camaro steering box using it's original style hoses and O-ring to flare adapter fitting on the pump's pressure side.

Re: Power steering on a ls swap

I used a gm corvette accessory drive kit on my 66 along with a Holley kit for my ac and it all worked flawlessly. I did however used a more modern steering box so the hose connections were a non issue.See pics in my garage.

Wow that looks amazing. I need a new steering box also so I’ll tackle that first. Dam, there’s so many upgrades I would like to do so. Oh did I mention, my Muncie is going behind the Ls so more work for me.

Re: Power steering on a ls swap

I'm running an LS truck pump, ZQ8 (Xtreme S10) quick ratio steering box, and 2005 tahoe hydroboost in my chevelle, used all the stock hoses. Looks like medusa threw up on the driver's side, but it turns and stops like butter.

There's a lot of places that have aftermarket brackets for your setup. Dirty Dingo, Goat Built, etc. Just be aware there are 3 different pulley spacing setups on the LS. Corvette is the tightest to the engine, then camaro, then truck. I'm running truck accessories w/ 0 space concerns.

Re: Power steering on a ls swap

Yes, I too am using the truck waterpump and accessories.

Bought the relocation brackets off Ebay...A/C billet bracket from Lsxinnovations and P/S & Alt brackets from ICTbillet. All fit perfect...97" serp belt from Jeep Cherokee.

Oil pan is Holley 302-2...multi-position engine mount plates are Lsxinnovation. Cam is BTR Stage II truck cam kit

Jeff, I have the same ZQ8 box as you in my 67. Mine isn't on the road yet, just wondering about steering feel and if the lock to lock limits are right.

Steering feel is great, like driving a new car, mine is pulling to the right though, unsure if it's a bad alignment or I'm off on the box alignment when I put it together. No complaints though, driving the car is a grin generator.

I’m going to look into a zq8 box. Does anyone have any part numbers to look for, or can I just go to local parts store and ask for a 2002 s10 extreme box? I tried an eBay search but only seen 1 or 2 under zq8. Thanks.

Re: Power steering on a ls swap

They're "rare" depending on who you talk to. Just make sure it's around 3 turns lock to lock. Older "SS" s10s had the quick ratio box as well, but yes, going and asking for an 00-02 xtreme steering gear box is the correct path. You will most likely have to pay a core charge.

Keep in mind I'm LS swapped, running a silverado pump, tahoe hydroboost, and everything bolted together. Unsure if you will need adapters for your hoses if you're still running a stock setup.

From past experience I would NOT run a camaro Z28 box. I tried one once on an S10 and literally had to make 3 point turns to get into a parking space, it was ridiculously embarrassing.

A lot of guys are talking about the grand cherokee box swap and t-bar. I found this info searching the other day:

Re: Power steering on a ls swap

With the mid 90s camaro pulley, did you have any issues with the pump heating up because it is spinning faster?
