Product Details

The King Engine Bearings MB 788XP is a precision-engineered crankshaft main bearing set designed as a direct-fit replacement for the Jaguar XJ 3.8L engine. Manufactured to OEM dimensional tolerances, this set ensures proper crankshaft support, oil film retention, and long-term durability in demanding engine environments.

King's XP Series bearings feature an advanced tri-metal construction with a copper-lead or aluminum-based overlay, delivering superior load capacity and wear resistance compared to standard replacement bearings. The XP designation indicates enhanced performance characteristics, making these bearings well-suited for both standard rebuilds and mildly performance-oriented applications.

Key Features:

  • Precision-machined to OEM tolerances for correct oil clearance and fitment
  • XP Series tri-metal construction for improved load capacity and fatigue resistance
  • Enhanced overlay for superior wear protection and longer service life
  • Engineered for consistent oil film maintenance and reduced friction
  • Complete main bearing set included for full crankshaft coverage
  • Manufactured under strict quality control standards by King Engine Bearings

King Engine Bearings is an ISO-certified manufacturer with decades of experience supplying OEM and aftermarket engine bearings worldwide.

First time and liked it.

Great, simple shopping experience. Best price on the web.

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

Very please with ease of ordering and checkout

Cheapest Bilstein shocks anywhere online!!

Was quick and easy

Quick-n-easy

It was easy and the price is good, but this is just the order. If I get the product in the same manor, that will be great. Thanks, Mike

It doesn't get much easier. I liked the PayPal and Amazon check out option. Tracking shipping information was very vague, not having any tracking number or any exact dates around shipping and expected deliver date (other than a window of dates). Overal

Best price and instant service.<br>What more can you ask for.

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.
