Lowering Rear End

Howdy, all. I'm running a stock 2WD 2006 W/T long bed w/ stock 245/70/17s and I am frustrated with the nose down, tail up look. I don't haul very much at all...no trailering, either. Mostly city driving back and forth to work. Been thinking about maybe lowering the rear end a bit to make it even.

 

1) How does that effect payload capacity? I do run and get a load of landscape bark for the wife every once in awhile.

2) Resale ramifications? Will it hurt my trade in value much?

3) How does it effect the ride/handling?

 

I'm not looking to "slam" the truck, nor do I want to do any front end mods. I will probably end up keeping the stock 17s on the rear, too. Any guess as to the cost of this? Would rather have a shop do this for me than try to do it myself and screw something up.

Lot's of folks here have dropped the rear approximately 2" using longer shackles. I'm sure payload capacity will take a slight hit but I doubt resale would be affected especially since the factory shackles can always be put back in place. Ride/handling shouldn't be affected either....you should be able to pick up the shackles for less than $60.

So is replacing shackles as easy as it sounds....jack up truck, unbolt old shackle, bolt in new shackle, repeat for other side, remove jack? Most of my DIY experience is just with normal maintenance things (fluid change/tune up/etc.)

I've run lowering shackles on the rear of all of my trucks since the 90s.

 

1. Payload: You are using the same suspension but you have to watch out at or near the limit because the axle will bottom out quicker.

2. Resale: No change whatsoever. Nobody will even know you did it but you.

3. Ride is actually smoothed out a bit due to the shifting of a little more weight to the rear.

 

It's not a big deal at all... Just do it.

Installation is a TAD more complicated. You have to put some jack stands under the frame with the wheels off of the ground and then use a floor jack to lift the rear axle and relieve pressure from the leaf springs. It helps if you have a friend do the jack work and you do the wrenching.

I agree totally with the friend helping run the jack make the process a lot easier in the end. Not hard a tall it is 4 bolts total, really easy with air tools but can be done with hand tools be careful not to tighten the shackles too much because of annoying squeaking and not allowing for flex.

 

I bet even cheaper then $60 on the shackles check ebay or around the site from other members, thats where I found mine.

 

Good luck

Ok, that makes sense. I am assuming you put the jack under the differential to lift the axle evenly? (Its looking like this is gonna be a one person job: me) Also, I found some drop shackles on ebay that have zerks. Are these better than non-lubed shackles? Or are all shackles pretty much the same? I don't want to put something on that is gonna bust on me at 65 on the freeway.

I use BellTech shackles myself. I like the fact that they have urethane bushings instead of the limp rubber the OEM ones have. Never had any problem. It seems odd to me to have a grease fitting on a rubber bushing...

One other point. Make sure you have the truck off of the stands and sitting on the ground BEFORE you tighten the shackle bolts. If not the bushings will be preloaded (twisted) and have a negative effect on the ride and maybe even the life of the bushings..

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Why don't I have a good scanner? I've always wanted one when I've needed one.   My latest reading says I don't need to do a relearn on the ckp sensor on a 1995 with OBD 1.5. The relearn is prescribed for the later-model 1995's which shipped with actual OBD II when GM completed the transition in prep for the 1996 MY. I need to confirm that. Did you know forums are disappearing? Knuckleheads on Facebook... it's not the same. It's just not.   So, scanners. Again, shooting myself in the foot for having eBayed my Snap On MT2500 "brick" with all the adapters. Not that I couldn't buy another but those are getting quite old, and mine wasn't new enough to work on 2000's vehicles.   Damn it (as I'm scanning my email between paragraphs here). Did you know there's a 2000 Jimmy 2-door on BaT that's ending this morning? It's local. I want it. 14k miles. Absolutely beautiful.   Back to scanners. MT2500's are old. Solus, now that could be a contender. There's a ~2008 Verus with a system error that's basically new in box for cheap. Hmm...I'm not sure about a scanner that runs an archaic version of windows (95 or CE, I can't tell).   I want the ability to reset and rotate TPMS, test individual modules, bleed ABS, electronic parking brake controls for servicing brakes, relearn procedures and other bidirectional controls.   Snap On does an MT2600. It's a new model as of last year, marketed as their "entry" scanner. Entry? Only where $1900 gets you through the doorway plus, I'm guessing, $1000/year if you wish to keep it current. So goes scan tools actually designed for production environments. Want decent products with excellent support, you pay for it.   Everyone is raving about Autels and TopDons and Foxconns and all these newer brands that are selling the $500 "prosumer" scanners for backyard hacks like me. They're tempting...honestly. Updates are cheaper, base prices are remarkably cheaper... And you get to deal with bugs and translation whoopsies and, well, just don't use it on anything expensive, OK? Having a dealer replace an ECU because it needs to be re-imaged after an adventure in scanning is no joke. But I think most people are getting by OK with these units.   eBay on a scratch-and-sniff pro-model oldie, a shiny new TopDon, or???   God dang it, I can't stop looking at this Jimmy. I'm ready! I'll Bring The TRailer! It's beautiful.

      What have you done to your K2 today?

      By Texasdeere · Posted

      I removed the OE running boards.  It looked so much better.  I wish I took them off a long time ago.     I had to put something back on for my wife.  I wanted Westin Sure Grip Running Boards but they are very pricey, like $600 plus.  I was going to go with the Ionic 41's like I had on the 2019 Silverado but went with Westin Outlaw Drop Steps instead, about $200 cheaper.  They are sturdy and functional but not super crazy about the look, but it works.

      Disable DRL's

      By fondupot · Posted

      I had a Gen5DIY DRL relocate harness from a 2022 1500 that I saved. I had Gen5DIY modify the harness for my 2024 Silverado 2500. Plug n Play, worked perfectly.    Here's a video I made for the 2022 1500 truck. The install is more or less the same on a 2500.    The harness relocates the DRL tot he top amber turn signal on my 2500.

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.
