Can da Spam!

Hello all,
Sorry for the performance of the website.   I've had to do some major house cleaning and enabled spam protection.  Deleted and blocked a whole bunch of spammers.
We are trying to make the web a better place meanwhile there are tools who have nothing better to do but mess it up for others.
Pardon our performance, it should be better now.


Throttle Body Upgrades

So you want to squeeze as much horsepower and increase performance for your 4.0 in your XJ or MJ?   A bored throttle body is an easy upgrade to do just that.  

  • There are various sizes of bored throttle bodies ranging from 60mm all the way up to 68mm!  
  • HO 4.0Ls factory throttle bodys are 58mm.   Renix is 52mm.
  • The most commonly used size is the 62mm.   If your 4.0L is stroked, you may need something bigger than 62mm depending on your intake manifold bore.

How to Flat Tow an XJ or MJ

What is Flat Tow?

Means the vehicle wheels are all on the ground and connected via tow bar.   

What do I need to do?

Depending on your XJ Cherokee or MJ Comanche specs, the transmission and transfer case must be set correctly to avoid any damage to the drivetrain.

  • Automatic transmission should be in PARK.   
  • Manual Transmissions should use 2nd gear.
  • Transfer Case should be put in NEUTRAL.
