Street Legal Headers by Doug Thorley

Street (CARB) Legal headers for the 4.0L V6 Xterras, Frontiers and Pathfinders is something that has been talked about for many years under the roof of Doug Thorley Headers. It never happened in the past with these particular headers. However, with the changes that have happened internally, Mike Johnson is now looking seriously at finally putting their Nissan 2005+ V6 Shorty headers through California testing.
Once this test is passed, all DTH-470-C headers would become street legal and all DTH-470-C headers manufactured moving forward would have a CARB street legal tag on them making them legal for street use and in smog tests.

If you have interest in these headers becoming steet legal, please reach out to Mike Johnson at Doug Thorley through any of the following avenues with your vehicles Year, Model and stating if you already have a set of headers or if you are looking to get a new set.

Mike will also be needing a 2014 Frontier with a specific engine block code to get the testing done. A free set of headers will go to the owner of the proper test vehicle if used to complete the tests.
Please help spread the word about this. Tell your friends, post on forums and social media.

3-Link Solid Axle Swap & 4-Link Rear Suspension by Rugged Rocks

Back in 2012 we finished the Rugged Rocks solid axle swap. I worked with Diamond Axle to make my H233B/Dana-60 Hybrid front axle. As you can see in the picture to the right, It’s not short on travel. The axle itself uses a H233B 3rd member from the rear of the early 90’s  – early 2000’s Nissan 4×4’s which has a ring gear of about 9.25″. This 3rd member drives Dana 60 axle shafts with Dana 60 kingpin steering components The shocks are 14″ travel coilovers with remote reservoirs. The brackets to make it all work are the same between the Pathfinder/Hardbody(’86-’95) generation of trucks and the first generation of Xterras/Frontiers (’98-’04) which are all available on the Rugged Rocks website, here: Nissan Solid Axle Swap Parts
Even if you don’t want to copy my design exactly, I have many Nissan solid axle swap parts available that are useable for your own design. There parts are listed below:
