Love spelab products diff cover is so mint the charge air cooler pipes look sick and the rad shroud pops when you open the hood Looking at other products but seem to be unavailable at the moment 🤘
These guys are great. They have fast shipping and their product is great. I wish they had more parts for my truck but they cant make them all i suppose. They added quite a bit of HP to my build. It turned out great
Best investment i bought and proud to have from SPELAB
Instructions were great, could
Be more detailed but overall great product, install wasn’t bad at all, unfortunately snapped oil dipstick tube following instructions but other than that I would say the plugs in the intake could’ve been put in prior rather than leaving room for install error
Very nice
Good products great pricing
Works great, find out how to wire it on YouTube if you aren’t sure, super easy though only two wires
this 2017 3500 Ram with now 111274 miles was used by PO to pull 5th wheel and now it pulls a 30 ft airstream TT.. I change out fluid at 96K with OEM cover and started looking for replacement.. this is great with magnetic drain plugs which is a great help as we change out oil every 35K miles as we tow a lot..
This new alum cover with fins is much like the AAM unit used on teh HO engines from factory with not quite the amount of and placement of fins but in the end this accomplished the goal of keeping the fluid cooler especially when towing.
One thing i did notice was the no actual instruction on what was proper level of oil in sight glass.. Usually on OEM cover you fill till the oil dribbles out the fill plug on cover and that if good..
on this model I noticed the sight glass was lower than the OEM plug determining the level need to be not the middle of the sight glass but at the TOP of the sight glass.. just saying.. the inside has fluid diversion fins so help move the oil to ponion gear and the side bearing on housing..
The fit and finish are great and it looks super cool now in the alum color.. I though about spray painting and sanding the edge of the fins to have that nice contrast but left it silver.
highly recommend and the price is right..
Order came in a few days earlier than the expected delivery day pretty easy install it makes the engine may look a lot better
I purchased a pair of Spelab Electric Cutouts for my BMW. Everything in the kit was shipped quickly, was perfectly packaged and the quality of their product is top notch. I installed the cutouts and I couldn't happier with the way they work. I was even able to pair the remote to the Homelink buttons to open and close the valves.
Hoping to gain a sponsorship soon I use yalls parts on my personal build and customers builds
Very good quality kit and was easy to install!! I highly recommend it!!
Excellent quality product that definitely delivers a difference in throttle response. You can tell that the engine is breathing much better. I highly recommend this to everyone out there. Shipping was fast too!! And to top it off, the dreaded engine killing grid heater plate is gone for good! Look how bad the grid heater was after only 46,000 mi. You can barely see thru the grids. Ridiculous design by Cummins/Ram. They should be ashamed for putting that piece of junk on such a good engine. Next up, turbo tubes!
Fit my 08 6.4 extended cab just fine. Sounds great with a 5x7 tip
I have always used there products and customers always are happy
Powerstroke Differential Cover FAQS
Yes—finned aluminum covers add surface area for heat dissipation, lowering gear oil temperature under sustained heavy loads. However, the primary value of an aftermarket cover is structural strength: stamped factory covers flex under load, while SPELAB's thick aluminum casting resists deformation from impacts and high torque. For trucks doing heavy towing or rock crawling, both the cooling benefit and impact protection matter.
The 1999–2016 Ford Super Duty F250/F350 uses a Sterling 10.5" axle often called a "Dana 60" in 2005+. The Dana M275 (2017+) is a larger 10.8" axle found on F250/F350 with the higher GVWR package—both use 14-bolt patterns but are not interchangeable. The Dana 50/60/70 10-bolt covers fit older Chevrolet/Ford swaps. Always check your axle stamp on the housing before ordering.
Yes—but only if the existing gear oil is clean and at the proper level. Most installers do a drain-and-fill at the same time since you have the cover off anyway. Use the cover's drain plug if equipped, or remove the fill plug to check level. Always use the manufacturer-specified gear oil weight (typically 75W-140 synthetic for heavy-duty applications) and Torque the cover bolts to spec to avoid leaks.
The 2008–2010 6.4L Powerstroke uses the Dana Super 60 front axle and a Sterling 10.5" rear axle. SPELAB's Dana Super 60 cover ($155, 42% off) and Sterling 10.5" cover ($155, 42% off) are both available. The Dana Super 60 is a 10-bolt pattern; the Sterling uses 12 bolts. Verify your axle stamp on the housing cover before ordering—6.4L rear covers are different from 6.7L covers.
No periodic maintenance is required on a solid aluminum differential cover. Check the gasket/seal at each oil change for leaks. Some SPELAB covers include a magnetic drain plug to collect gear wear particles—check it at every service. Unlike fluid-based coolers with lines and fans, a finned cover is purely passive. Inspect mounting bolts for tightness after the first 500 miles after install.
