So, what are the drawbacks of using rear shock extenders and stock shocks, versus installing shorter shocks?

 

And does anyone make shorter bumpstops that can be mounted to the OEM bump stop bracket?

Nothing that I can tell. I am running my stocks shocks with extenders. Rides like stock. As far as bump stops belltech and mcgaughys sell shorter ones but I don't think there's much advantage to utilize them on the stock perches bc with mine I had my stock ones trimmed as low as I could and I was bottoming hard only being lowered 4 inches. 8f lowered less than 4 inches then you can just trim the stock ones.

Mcgaughys bump stops and shock extenders

 

You might still have issues with the McGaughy's bump stops on some harder bumps, if you do you can look into the energy suspension ones, they are even shorter but still provide plenty of bump stop.

Shock extenders try to keep the shock in the ideal dampening range but they can also effect the geometry of the suspension and so you are possibly going to wear the stock shock out faster just for a different reason. With stock shocks and no extenders you are actuating the shock outside the ideal range it was designed to work in. Stock shocks with shock extenders helps to get it back in the ideal range but applies more lateral force to the shock because the additional angle. For what the rear shocks cost on these it is probably a good idea to go ahead and just replace them with drop shocks but make sure and read around as there are some out there that will make the ride worse.

 

I think the common agreed upon belief around here is that the Belltech drop shocks are the best ones for our trucks.

Depending how much drop you have, could also look into the Bilstein 5125 as they come in custom sizes and valving. RideTech has the same thing with their shocks (built by Fox) they like them a lot though. LOL

 

I have the 5100's on rear of mine, lowered via shackles and block removal, not using the shock extenders, I may put them though at some point

Combination of Belltech and DJM to give a 4/7 drop. Goes back in for air assist in a week so I can still haul a race trailer (which is the whole reason I bought one... can't put a Class 3 hitch on a CTS-V Wagon.)

Looks great Croak. Nice & clean. What size wheel & tire setup are you running? Those are all terrain factory replicas right?

Thanks! Yes, they're 285/40/22 Falken Ziex tires on OE Wheels LLC reps. Couldn't justify spending 3 times as much on the OEM ones and then having to pay to strip the chrome and powdercoat them.

Got some OEM SEY 22" now I need to get smaller tires these 285/45r22 rub. Any suggestions?

I run a 285/40/22 Falken Ziex STZ05. Toyo makes the Proxes ST2 in the same size.

I rub a bit at full lock 4/7 on 22's. I'm guessing you'll have more issues because you're an inch higher (which has you covered vertically for clearance, effectively a trade-off with my measurements) but that still puts the tire an inch further out from the hub so you're an inch closer to rubbing on the inner side of the wheel well when the steering wheel is cranked.

 

:EDIT: Also depends on your offset, obviously. My setup is pretty close to stock offset.

I will look in to that. Was looking at 285/35/22 but that seems too small. I see that you wrote that you rub on full lock which is not a big deal to me. Any issues on bumps?

Probably depends on your offset, I see you have OEM wheels. Mine are tucked like stock fitment and I haven't noticed any rubbing at speed but it rides like a covered wagon. I'll bottom out the bumpstops in the rear before anything touches there, I haven't managed to rub up front yet other than cranking the wheel in parking lots. Scraped the front air dam a few times.

    • A little girl said her prayers every night before bed and she asked G d to watch after each person she loved. One night she forgot to pray for her babysitter and her babysitter died. A few days later she forgot to pray for someone else and they died. The next night she forgot to pray for her dad. The next morning her dad was terrified. A bus almost crashed into him. He almost fell off a fifty foot ladder and almost wrecked on the way home. When he arrived home, he said I had a terrible day. His wife replied, “You think you had a bad day? My aerobics teacher died during class.
    • Nice! I had one here, once. The car dealer I used to haul for stopped by with it. That was over 10 years ago now. Those are SUPER rare these days, especially up here! Never even see them at car shows anymore.   https://postimg.cc/0rvcNZ1W
    • I remember watching one of the auctions on TV. It just happened that they had two little red express trucks. My brother bought one new in 1979, still has it. So I hung on to watch them cross. The retro redone example brought more bids and went for more money than the original one did. My brother has redone his 3 times and raced it. He’s now in the process of making more tame for cruising. 
    • I always upgraded the suspension and steering components - bushings and ball joints, and had older cars that I could out-corner ANY modern car with. I used to be able to take my '78 Cutlass on off-ramps at stupid speeds and make the sharp MA corners without even squealing the tires. So much fun. My '72 El Camino must've had work done by the previous owner, since that thing seemed to handle even better than the '78.   I think the suspension & steering on the '72 was much more advanced than the '64, so that probably just made a good system even better.   I'm the same way with vehicles. I hate having to worry about the paint on my '93 W250 Cummins. I'm not used to that, lol.   https://postimg.cc/mzKr55sY
    • BEAUTIFUL!! That a Cutlass F85? Or 442? My side-ID skills are lacking thanks to failing memory, lol. Love that color & year, too!   Yeah I was never big on entering my own stuff, but I always liked seeing what everyone had, the rare models, and what's been modified. That was always fun. These days I have barely enough time to do what needs to be done at home.    Oddly enough, here in MA there are more car shows than ever in history! You'd think up here it would be dead, but it's bigger than EVER!          Took the 940 for its maiden voyage with the carburetor. At first I couldn't get out of the yard! This originally had the "Bosch" system (our other 940 has Regina - single fuel pump in fuel tank, and space-age-looking ignition coil on driver's fender) - that has dual fuel pumps. One in the tank, and one under the center left of the vehicle. I had unplugged the external one thinking I wouldn't need it with the carburetor ... but the way I have the pressure regulator hooked up, 90% of the fuel volume is going back to the fuel tank, so cranked all the way down, the regulator is only supplying a hair above 3.5 PSI to the carb. Turns out the in-tank pump (15 PSI alone, instead of 45) couldn't handle the load. Plugged it back in and went for a rip. Ran great!   Throttle response is always amazing with carburetors. ZERO delay that no FI system can reproduce. Also fires up in half the crank rotations as before. Low end power was DRAMATICALLY improved. There was an ongoing lean issue with the FI that I got tired of figuring out, so this is a MASSIVE improvement! Above 50 MPH on hills it feels SUPER weak, though. This is more than likely due to the timing not being advanced enough by the computer, since it believes there are multiple failures. I can live with that through the winter. Will keep me from passing slowpokes where I shouldn't and getting speeding tickets at least. 😁
