Product details

The WCFab ARP Bolt Kit for 2001-2016 Duramax Up Pipes or LB7 Turbo Down Pipes is comprised of 6 specially selected high strength 12 point ARP fasteners and matched washers with a pack of assembly lube and are designed as an upgrade to the aging OEM fasteners used on the 2001-2016 and newer 6.6L Duramax engines to connect the up pipes to the exhaust manifolds and turbocharger pedestal or the down pipe to turbo exhaust outlet on the LB7. During our performance development work on these engines we have seen numerous occurrences of factory fasteners seizing or breaking in the manifolds, pedestal, or turbine housing. This kit is a simple, cost effective upgrade for peace of mind and ease of serviceability for both stock and modified trucks. - - Torque to 54 FT LBS - - Replaces the following GM part numbers: 11611132 Wehrli Custom Fab Up Pipe Bolt Kit, for 2001-2016 Duramax / LB7 Turbo Down Pipe Up Pipe Bolt Kit, for 2001-2016 Duramax / LB7 Turbo Down Pipe

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is quoted in your reviewed estimate before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
