Differential Cover For Ford F150 1997-2017 | SPELAB

Great So Far — Helpful Installation Tip

Installed this on my 2012 F-150 5.0L using a LubeLocker gasket instead of RTV. Installation went smoothly, and so far everything is working great with no leaks.

One helpful note for other buyers: I couldn't find the recommended cover bolt torque specification in the documentation, so I contacted SPELAB support. Their technical team confirmed a specification of 25–30 N·m (approximately 18–22 ft-lbs). I torqued mine to 20 ft-lbs.

It would be helpful if SPELAB included this information in the installation instructions. Otherwise, very happy with the purchase so far!

Number one fuel line not fitting properly.

The fuel line they sent with the intake horn did not fit properly and also there was a issue with the flare nut not reaching the threads

Amazing customer service

I have been having issues with the tune (hopefully not the tuner). I emailed customer service with my concerns and got a response within an hour. I didn’t even think to check my email that quick because “normal” customer service takes days. They responded both times in such a rapid manner I was not able to respond with the issues that fast. They have been great to deal with. I will continue to purchase from them because of that alone

FAQS

Yes. GM made a mid-cycle change in 2015.5 affecting EGR plumbing and exhaust routing. SPELAB sells separate DPF delete pipes and All-in-One kits for each sub-generation — confirm your build date before ordering.

The full kit with tuner ($1,349) includes an EFILive or EZ Lynk device. The hardware-only kit ($309.99) does not — you'll need to source tuning separately for CEL elimination and proper fueling.

Strongly recommended. The LML uses a CP4.2 injection pump prone to catastrophic failure if diesel contamination occurs. A Fuel Sump Kit or CP3 conversion prevents pump cavitation and protects the entire injection system.

SPELAB's LML EGR Delete Kit removes the EGR cooler, EGR valve, and associated hardware. The optional High Flow Intake Elbow replaces the restrictive factory elbow for improved airflow post-delete.

No. SPELAB's LML DPF delete pipes are not compatible with Cab & Chassis configurations. They fit standard Crew Cab / Extended Cab pickup bodies only.

A full DPF/EGR/DEF delete with custom EFILive tuning typically adds 80–120 hp and 200+ lb-ft torque. Stock LML produces 397 hp / 765 lb-ft. Results depend on tune calibration and fueling upgrades.

Yes. The LML uses DEF (Diesel Exhaust Fluid) for SCR aftertreatment. The All-in-One kit addresses DPF, EGR, and DEF together. Deleting only one or two systems without tuning will cause derates and fault codes.

The CCV PCV Reroute Delete Kit for 2011–2016 LML relocates crankcase vapors away from the intake. It's compatible with 2004–2010 LLY/LBZ/LMM as well, making it a versatile upgrade for multiple Duramax generations.
