The price of the Gen V 5.3's is dropping rapidly, currently they do not cost much more than a Gen IV 5.3. The yards are gouging as usual on the 6.2's, the 6.2 is in high demand and they ask top dollar. The cost of the 5.3, like the 6.0, is a major factor for the swap. I have been doing engine...

Gen V 5.3 startup The Gen V 5.3 L83 engine has a lot of promise. With direct injection, high compression and CVVT we hope it will have the mid range torque a heavy JK requires. We are hesitant to recommend the Gen IV 5.3 in a heavy JK because the 6.0 does a much better job hauling the weight...

LS3 is an awesome engine, pretty much the pinnacle of old American V8 technology. The LS3 is very mild but has a lot of power and excellent drivability. The LS3 does require premium gas and synthetic oil but runs for 200,000+ miles and maintenance is low. The Gen V engines are bringing in...

AFM is almost useless in a heavy JK. In Gen IV engines AFM only kicks in under light loads but when turning 40's on a lifted, heavy JK your rarely under a light load. Light JK's with minimal lift and 32's may see 1-2 mpg increase. We can turn AFM off since it can be annoying. Gen V engines have...

Both work but I am partial to our JK drive. If running the GM drive it's best to have a 3" lift or the passenger UCA will get close to the AC compressor. We do offer a compact Sanden compressor for the GM drive that gives good clearance. With the JK drive the AC and PS hoses remain stock, with...

You can go either way. If running our JK drive you can retain your PSC PS pump and hydraulics. If running the OE GM drive you will use the GM PS pump. I feel the GM pump is a good choice, it is quiet and has plenty of volume and pressure, they use these pumps for hydroboost. If running 40's...

Yeah PS hydraulics. I don't like noisey pumps either.

Were sending our first Gen V kit out for feedback. We are installing a Gen V 6.2 with 8 speed in a high profile build, I will have pics up soon.

Here you go Dean, this is your JKU. This video shows how simple and quickly the swap can be done with experience. https://www.youtube.com/watch?v=vDoqQIrbWsI

Were booking in house swaps now, kit available in about a month.

Gen V I just put a few miles on the Gen V 6.2 JKU. Very impressive, it drives different than the Gen IV's. The engine feels more aggressive. With the Gen IV engine the programming kept the rpm's as low as possible, then when you needed to accelerate the transmission would downshift. This...

Another quick video of the Gen V 6.2 JK. Were learning the new technology that the Gen V engines employ. The brake pedal position sensors are critical to engine operation on these Gen V engines. The BBPS is used for torque converter control, torque management, cruise control and other functions...

LFX engine Somewhere I promised an LFX video, here it is. Over 300 HP with a 6 speed automatic transmission. Some variants are over 400 HP plus it is compact and light. We have much of the network online here including the cluster. We have the driver information center operational for guys that...

Try it now?

Hi Guys, This is literally the first drive out of the shop; the first functional Gen V LS JK Direct Injection, Continuous Variable Valve Timing and the Vacumn pump all worked perfect. If the mileage claims are true this may be the ultimate Jk engine, I'm excited to drive it...

The 6.0 has plenty of power for 40's. The 6.0's are intended for HD trucks so they have a lot of low end torque, similar if not more than the 6.2's off the line. The 6.0's have VVT and the LS3 does not. This means the 6.0 has great bottom end to get you rolling and at about 4,000 rpm the torque...
