Have a set of Jeep 2.5L Inline 4 Cylinder connecting rods with noisy or damaged pistons? Let us do the work for you!

This listing is for our Piston Installation Service. Simply send us your connecting rods, and we’ll take care of the rest.

Once we receive your rods, we will:

• Remove your old pistons
• Thoroughly clean the connecting rods
• Inspect the rods for cracks, damage, and wear
• Inspect the connecting rod bearing surfaces to make sure they are in good usable condition
• Install your new Sealed Power pistons onto your connecting rods
• Return them to you ready for installation

We'll get your rods and new pistons assembled and ready to go so you can get your Jeep 2.5L back on the road for many more miles!

Shipping: We can provide a shipping label for you to send your connecting rods to us. Contact us by email or mail if you need assistance with shipping.

IMPORTANT: This service is for installation of pistons onto your existing connecting rods. Rods will be inspected before assembly. If we find a rod that is damaged or outside of what we consider usable condition, we will contact you before proceeding.
 
 - After years of buying, tearing down, and rebuilding Jeep engines, DeXJs has seen firsthand how these factory pistons can become a major problem. Cracked pistons, broken piston skirts, excessive piston slap, and wrist-pin noise are issues we regularly encounter when dealing with these engines.

 -The problem is that replacing a failed engine with another used engine can simply put the same problem back in your Jeep. A used engine may run great today, but if it still has the original pistons, you may only be buying time before the same issue appears again.

 - That's why we started offering NEW replacement pistons pre-assembled on quality connecting rods — giving you a way to replace the problematic factory pistons before they fail, without having to hunt down and rebuild an entire used engine.

YOUR PURCHASE INCLUDES:

• 4 NEW replacement pistons
• Complete set of NEW piston rings - NOT Installed
• Pistons installed on your connecting rods
• Ready for installation - Rings are NOT Installed

IMPORTANT — KEEP YOUR ROD CAPS MATCHED!

DO NOT MIX UP YOUR ROD CAPS!

Each rod cap must remain with the exact connecting rod it came from and in its original factory position.

Typical turnaround time is approximately 2 weeks from the time we receive your rods. 

 - I usually have the pistons changed on your rods the same day we receive them and shipped out the following morning. I say 2 Weeks just to cover if I am busy or away from the shop! 

Piston and connecting rod assemblies are non-returnable and non-refundable. Please make sure you have verified that your engine is suitable for rebuilding before ordering.

 -  ADD KING ROD BEARINGS & CHECK YOUR BEARING CLEARANCE

If you're replacing your 2.5L pistons, this is the perfect time to replace the rod bearings while you're in the engine. We now offer KING brand rod bearings — a high-quality bearing option at a great price for your 2.5L rebuild.

For just a few extra dollars, we also offer Plastigage for checking your actual rod bearing clearance during assembly. Don't simply assume the bearings are correct because the parts look right. Checking your clearance during assembly can help identify problems before the engine is put back together and help ensure the proper clearance for long engine life.

NEW PISTONS + NEW RINGS + GOOD ROD BEARINGS + PROPERLY CHECKED CLEARANCES = A MUCH BETTER START FOR YOUR 2.5L REBUILD.

 - IF you are reusing your rod bearings - Keep them, do not send them to me. My cleaning chemical will destroy them.

Protect your investment!

Our piston and connecting rod assemblies are high-value, heavy engine components. For $10, you can add shipping protection covering your shipment for up to $650 in the event of loss or damage during transit.

Standard carrier coverage is limited to $100, so we highly recommend adding the $10 protection to your piston assembly order.

WHAT'S COVERED

This optional protection is intended to cover your piston and connecting rod assemblies if your shipment is lost or damaged while in transit with the shipping carrier, subject to the carrier's applicable terms and claim requirements.

IMPORTANT

Once your package has been accepted by the shipping carrier, the shipment is in the carrier's possession. If a package is lost or damaged during transit, the customer is responsible for submitting the required claim with the carrier.

For a $500+ engine component, we strongly recommend the additional $10 protection.

PLEASE NOTE

This $10 shipping protection is ONLY for orders containing eligible piston/connecting rod assemblies. Do not purchase shipping protection by itself.

OVERSIZED PISTON OPTIONS

Most Engine rebuilds will use standard bore pistons to replace the original OEM pistons. If your machine shop determines that your engine block needs to be bored oversized, we also offer oversized piston options.

CLICK HERE to order oversized pistons.

Oversized piston orders are special-order items and typically require approximately 2–3 weeks before they are ready to ship.

IMPORTANT: Do not order an oversized piston based solely on the condition of your original pistons. Have your engine block measured by your machine shop first and order the piston size based on the final bore size recommended by your machine shop.
