    LB7 to LLY heads question?

    So far the 03+ have not had an issue on the OBD2 side, it's only been the 01/02 with LLY electronics that get kicked back for some reason. Nobody has had an issue with the Ref, they just give a compliance sticker for future smog's. Either way, your conversion is 100% Cali legal because all smog...

    LB7 to LLY heads question?

    01/02 * (LLY using LB7 electronics) I only do this job in house, my cell rings Constantly about this swap. I will not send or sell a tune file. If you need tunes, Rob and I had countless hours into this and he could assist you. It's possible to get running good, but You'll go crazy trying to...

    LLY: 2005 Duramax mystery T connector

    The motor will be much happier if you leave it as routed, just fix the seeping clamps and cracked rubber line. You don't want that oily mist introduced into the turbo as it came from factory. I'd be more concerned with what looks like a coolant leak on the turbo coolant stat housing.., and the...

    Lift kits

    Cognito makes nice quality product, & has the price tag to go along with it. We've been one of Cognito's top dealers for many years now, and have seen very little come back for warranty claims. Most are the Bilstein shocks, and it's very rare we get a Fox shock issue. I've installed pretty much...

    LML Level????

    Center of hub to top of wheel well should not exceed 26" max (leveled). Without hacking up the truck, a 33x11.50 9" wheel with 5.0-5.7" BS is about max. If you want to go bigger or wider, you can find a link to the NCT fender mod at the site below.

    Won't start after alternate fire cam

    Crank the motor over with the sensor & sensor housing pulled out, see if the reluctor is bent. Could have been dropped and tweaked slightly.

    Won't start after alternate fire cam

    Longest Sensor plug (last on the harness) is going to the cam correct? And you have cleaned the block to bare metal where the ground goes (ground wire next to cam/crank sensors)? Ohm the wires at the plug back to the bale connector, and then to the fuse box (while bale connector connected), I've...

    Bilstein 5100 Longevity

    Fox will have less shock fade when being abused compared to a Bilstein, they are rebuildable and much easier to deal with if you ever need to warantee one or more. If you plan on abusing them all the time off road, the Fox resi's work great also.
