ARB front bumper,got it 14 years ago from 4 wheel parts($600 back then).

Cool, thanks. I have a front hitch on right now and the winch on a cradle to put front and back as needed, but would like something like you got there. I'll look it up. Thanks again.

B&G does stock+ reflashes for the KJ's and once you go past the CAI/TB/Catback level they'll do rolling tunes - there's some gains in it between 2200 and 4400 - roughly 25 ft lbs at any point along that curve and it gets rid of the torque drop at 4150 that was a result of the stock torque management kicking in

i built mine only for the purpose of the rebuild, and learning about the motor - if i had done it for the purpose of juiced up power yields i would have done an engine swap - it cost me about the same

It's a Jeep... not a Corvette. Drive it as it was meant to be driven.

Some cars/engines lend themselves well to modifying, there is room for improvement. The Chrysler engineers did a pretty good job getting the most out of the 3.7L without overbuilding or over-spec'ing the engine for it's intended purpose.

If you bought a KJ to go fast, you bought the wrong vehicle. If you think it's under-powered, trade it in for a Grand Cherokee with an HO engine.

Hard to beat a ARB front bumper
Got mine leass than 6 months after I bought the 04 new.
After hitting 4 different Deer at highway speed, a Toyota Camry ( that had to be towed away, ) a GMC 3/4 ton pickup it was still in great shape. They save you money every day you have them! LOL
This picture is after the Deer and the Toyota

No won't bolt up afterwards
Never was hurt at all
The 4 deer were on 2 lane road near where I grew up just like hitting a speed bump, stop back up, finish killing them, call the Law and take em home ha ha
Toyota pulled out in front of me, I was doing about 40-45 in town, legal speed , then the guy just stopped dead. Police seen it all and gave the guy all kinds of H ! :Insane:

That's my normal driving style.

You don't want to know what I've hit with my ARB,heck just recently my rear gas tank skid and rear Riddler diff cover totaled a civic(took the whole top of the motor off).

They don't have the acceleration my Cherokee had stock. This V6 just doesn't do as good at getting a move on as that straight 6 did. Sometimes I wish I could just swap it out for the straight 6.

XJ's weighed about 3200-3400lbs and the KJ starts at 4000lbs and goes up to 4300lbs(CRD's).Take that same 4slow and put it in a WJ and now you'd think the KJ is a sports car since a WJ with that engine can't even get out of it's own way trying to move a 4200lbs Jeep.

Besides that 4slow is not even worth hauling to the junkyard for scrap.

Having owned 3 XJs I bought new, ran up into the 250,000 mile range, I'll take the 3.7 over them any day of the week.

Nope it's the Kilby gas tank skid.

Oh and if anyone wants to play my personal record is about 1000' for sending a shopping cart across the parking lot,via the ARB.

How fast were you going when you hit said shopping cart?? :gr_grin:

My sticker on the inside of my driver door says my rig weighs 5600lbs. Where are you guys getting 4300 from?
