2007 silverado classic lowering


Recommended Posts

Posted

Hi everyone,

 

I recently bought my first brand new truck, it's a beautiful white 2007 Siverado Classic Crew Cab. :) I'm thinking about the mods that I can do to it. One of the first things I want to do is lower the suspension, but I'm a little confused. I called one local shop and got a quote for $799+ tax etc for a 2"/4" drop.. They mentioned that they would install new spindles, shackles, and hangers. I thought it was a little on the high side with the price. Then I called another pretty popular shop in town, they quoted me $525 otd. This other shop won't change the spindles, they only mentioned changing the springs in the front and rear, and of course an alignment. I would also have the choice of a 2"/4" or 3"/5" drop for the same price. I like the $525 price better than $799, but I'm not sure that it would be the right way of doing things. I'm concerned about the ride quality and if it would be bad for the truck in the long run. Anyone got any ideas/suggestions?

Remember when your doing searches, that the 07 classic is the same as the 06's!! Lots of guys on here have them lowered, just search around.

I did 2 inch torsion keys in the front and removed the factory 2 inch block from the rear. Then I added 2 inch drop shackles in the back to get 4 inchs. McGaughy and Belltech make good kits for our trucks. My truck is a 07 Classic Sierra Denali.

I lowered mine because it looks good and rides really nice. I didn't spend all this money on my Denali truck to hammer it and take it offroad. Some of us have open minds and don't care if someone else lowers or lifts their trucks. Some of you apperantly have a problem with it. As you can see, I have a lifted truck-I don't need two. Plus, my truck gets better mileage being lower to the ground.

thanks for the input sikgmc, glad to hear from someone with an open mind :cheers: . I don't need a lifted or stock-height truck. for years I've always owned sedans, this is my first truck ever. The main reason I got it is because I ride a dirt bike and needed something to transport it with. I won't be doing any towing, nor do I need a 4x4 to get it into the mud. I always drive within the city limits, in fact, I live within 10 miles from work, so the truck won't even see that much mileage on it. With that being said, it's not a "useless" truck to me if I lower it, I LOVE the look of a lowered truck, in fact, I won't be fully satisfied until I lower it one way or another. Now, if I lived out of the city limits or in a place where there's lots of snow/mud and used it as a "work" truck, then I would not even consider lowering it. I'm an office worker, my work area is within the limits of a cubicle, I'm no farmer, I have no use for a "work" truck, to me it will be like driving a large sedan with a cargo space for whenever I need to take my bike around with me. Well, that's the end of my venting session.

 

Anyone else got some constructive input on the matter?

I totally agree. I lowered mine for the same reason as you. I own a CNC machine shop and most of the day my truck is parked in a parking lot. I still however tow a 6000lb trailer, I still tow my boat, and I still through stuff in the back. So like you, my truck isn't worthless either. Some people just think if its a truck, it should be big and ugly. Most of the people that think this way are usually broke down somehwere or stuck in the mudd just off the road. I get a good chuckle when I see them around here as I drive to work in my nice smooth quite ride, which by the way, isn't broke or dirty.

Take this for what it's worth because I don't have personal experience, only what I've heard.

 

if you do springs instead of spindles you change the suspension geometry and place pressure on the ball joints and other components because the truck is acting like it's got 2" of travel on it at all times. You'll also need new shocks that account for the 2" spring change. If you go with the spindles, the suspension and steering geometry stay the same and you use stock springs, shocks and everything else. IMHO this is the way to go and also IMHO it's easier to change a spindle than to do a set of springs if you change back at some point. YMMV.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
