ProCharger Supercharger Kit Installation & First Start-Up on 2021 Gladiator Rubicon

[Greg_L]

Again it's a Jeep so no I don't want 18k or even 7k rpms. Power that comes in quick and peaks before 5k, especially mated to an 8 speed auto is perfect. Is it a drag build? Of course not. Will it work great in all types of terrain? Absolutely. Only the Toyota guys are ever out here bouncing off the rev limiter rock crawling.... and that's because they only make their 100hp at 6k rpms.

Whatever floats your boat man.

It’s a procharger, you can get better mpg, supercharger is a more broad term.

ProCharger is a supercharger. Like Coke is a soda pop.

I had to specify if my car's engine was 500 HP or below, or over 500 HP when I ordered a new fuel pump from RobbMC last week. There's a reason for that.

Who is RobbMC? I am trying to find a higher flow fuel pump for my 2020 SC'd Gladiator. We are now running 660cc injectors and getting around 525hp at crank (420 to 440rwhp) I'm in Australia.

He's performance parts - started out mostly for AMC cars but has other stuff as well, including Chevy fuel pumps for small block chevies up to the 400. (mechanical, engine driven) For carbureted engines.
Sounds like you need electric.

After a long wait my ProCharger showed up! After searching the internet there was not many detailed write up on it. I will do my best to keep this thread updated with what it took to install, actually running with it and longevity.

2021 Rubicon
28,000 miles.
5.38 gears on 38s
Magnaflow rockcrawler muffler.
Fresh spark plugs and gapped to spec.

The Procharger kit is top notch! All parts and materials are not cheap products. The packaging of each part set is done very nice with everything labeled. One of the best instruction manual I have seen for a product in awhile. My only complaint would be the instructions jump around a bit and dont finish a process, so if do not paying attention or read ahead you will do some steps then go back to finish it later. The Kit fit like a glove and there was no real fight to get the part on because of manufacturering flaws.

Thing you have to deal with.

Spark plug gap or replace with new.

PCV lines all needing hose clamps or modified.

New fuel injectors.

Relocation of alternator

Routing new intake tube's.

Routing new serpentine belt in new configuration.

Moving radiator back and mount intercooler.




The total install with 2 people took about 8 hours. The install was pretty straight forward with no major modifications to the vehicle. This is a OEM bolt on for a Jeep keep in mind, there is not much room to begin with. If you are not good with your hand this might not be a kit to DYI. I found most was difficult but lots of tight finger tip work while holding up parts. You could do this with one person but two people made it nice.

IF YOU HAVE the baxter oil system you will need the model that relocated the filter. The fixed filter model will interfere with the Procharger! My friend got a free kit for his JK and I have a new one on the way.

If you have any questions feel free to ask me, I physically installed this myself so know all about it now lol.


We did not realize we need to send stock Pcm file back to Procharger. We will have to wait to fully see what it does. Being who we are we did take it for a nice stroll down the road, with stock tune it was already a big improvement!




This is the 1/4mile information before we tore into it.

I am not a jeep expert any means. I have a question for you Dickster. I am considering getting one of these prochargers to help with smiles and towing power. Right now I tow a 5000lb camper and do well on flat surfaces etc but I live in NM and we are at 5000 feet above sea level in the low spots of the city and to get our of the city in most directions I need to go over 7000ft above sea level and when I pull my camper to Colorado or Utah etc I go over 10000ft above sea level and it gets a little tough. Do you think the procharger will have a positive / negative or neutral effect on towing power? also now that you have had it on for over year any problems or concerns you can make us aware of?

NA engines lose 3% per thousand feet of elevation. The 285hp v6 is below 200hp at the crank at 10k feet. Subtract another 20% for drivetrain losses and your lucky if you've got 160hp to the ground. Conversely the procharger adds 140 wheel hp or ~175hp at the crank. Forced induction only losses 1% per thousand feet. You'd still be pushing ~415hp at the crank at 10k feet and ~325hp at the wheels. I'd bet the pink slip to the gladiator that 325hp at the wheels pulls a whole lot better than 160hp.

Thanks!

Thanks for the feedback. I am debating on a replacing my 2020 gladiator with 110k miles with a new one or a ram RHO.

The trx is back for 2026... with 777hp.

I have about 9k miles on it since install. It definitely quite noticeable in power. I gained about 2 sec in in the quarter mile. Its still pretty slow since im pushing 40s with 5.38 gears. The Procharger is vacuum operated and it typically kicks in around 2500rpms and it's enough to feel it pull without any more throttle input.

I have never towed anything with my Gladiator so I couldn't tell how it performs in that aspect. I would imagine it would do fairly well since power is power? I will say in town I went from 13mpg to 10.5 and open freeway around 70mph I get around 15mpg.

I have been happy with my install and its been fun having the extra punch. When on trails and around town it turns heads when it spools up lol. The tuning aspect might be iffy with elevation change and I definitely get a different tune to load for it. There is a lack of support with gladiator tunes and would have to source someone local. Try getting a hold of Diablo sport, they have some tuner that works for the gladiator and they have a few Trans tune for it as well.

I have a Ram 3500 6.7L I tow with so the jeep is just a fun vehicle. 5,000lbs puts you at the 80% safe towing mark and if your towing a lot I would be upgrading. Now the RHO i would not get not a v6 towing kinda guy. Like stated by others the 8v is coming back and my old 1500 5.7 would love towing 5k around.

I think the RHO is gonna 'struggle' towing because of its soft suspension - it's unlikely the 540HP/521TQ is gonna be the shortcoming, even if it's 6 cylinders

I'd buy a TRX - but because of V8 noises, not power.

I'm not in the market for either though

I don't think the rho rear suspension is any softer than the mojave and it tows fine. The OP is only pulling 5k pounds and his biggest gripe is power at altitude. The RHO would definitely solve that.

That's why I said 'struggles'.

It probably tows like shit compared to a normal half ton that doesn't have pillowy suspension.

Probably tows fine compared to most Gladiators. Better in pure power.

My coworker has a TRX - which on the suspension side is more or less the same truck I believe, and it wallows along the road likes its on its fifth trip to the buffet line.

It's fast and it feels like you could drive over the local railroad crossing at 100MPH. Just doesn't feel like hauling anything would be its favorite job. Again. no worse than a Mojave to your point...

But yea - probably fine for his use case. I'd rather do that than put a supercharger on a 3.6L.

Yeah I am not worried about the suspension. I tow it with rubicon now with metal cloak 3in lift with metal cloak black shocks and 38’s right now. A weight distribution hitch solves most of the sag and I will do towing airbags if needed but no sag on current rig even fully loaded and no sway either
