    Product Description

    SDP 3" High-flow Billet Y-Bridge & Intercooler Pipe kit - LBZ LMM

     *Cannot be sold or shipped to California addresses*

     

    This is our new high-flow billet 3" Y-bridge with a full 3” bore! We used computational fluid dynamic software to test the air flow and turbulence in the factory Y-bridge, and using the results from this testing, we implemented a diverter vane on the inlet that splits the airflow to both runners and maximizes flow potential and minimizes air turbulence. This translates to real world results, you'll notice quicker responsiveness and HP gains. Machined on our 5 axis CNC mill and designed in-house, our 6061 billet Y-Bridge not only has a perfect fit, but is the only Y-bridge on the market of its kind. Our 5 axis machine Y-bridge requires less setups than a 3 axis machined part, meaning the flange surfaces are machined in the same operation making for a 100% perfect fit every time. Due to the nature of others hand-fabricated units, welding them results in warpage and distortion, they will never fit 100% perfectly. Others 3-axis machined Y-bridges require multiple setups that add time(cost to you) and the potential for human error with misalignment that you will notice on install.
     
    With our steel bolt-on neck, there are no worries about clamping the T-bolt clamp to the silicone boot too tightly and bending the tubing (such as with aluminum tubing designs), and the provided silicone o-ring ensures a proper seal at all boost levels. Other cast designs with 3" OD are typically 1/2" smaller ID (inside diameter) than our billet design, which dramatically reduces the amount of air it will flow. With our Y-bridge you get the best of both worlds, higher flow AND strength, along with the easiest install for a 3" Y-bridge available!
     
     

    -True 3" Y-bridge that is perfect for trucks with small or large twin kits! Also works with the factory turbo configuration.

    -Tubing has precisely rolled beads to make install easier and keep the boot from blowing off.

    -Includes miscellaneous parts which are all made in the USA such as the black aramid reinforced silicone boots, T-bolt clamps, heat shrink wrap, high temp silicone O-ring and any necessary mounting hardware.

    -Includes both Intake runner to Y-bridge gaskets

    -The 09-10 trucks require a MAP sensor seal which is included in the kit.

     

     

    The Y-bridge, studs, intercooler plumbing and intake horn are all manufactured under the roof of SDP's shop with our custom powdercoating to top it off in any color that you choose.

      Lbz y bridge kit

      Posted by Nick on 31st Aug 2020

      Let me start off by saying this is a pain in the butt to install. Took me a day and a half to do mostly solo. When I got the parts in the mail I was shocked at how well they packed it, ceran wrap on everything, and lots of other packing material. The powder coating was perfect, well worth the money. Looks so much better under the hood now.

      Y-Bridge Install

      Posted by Hunter Jones on 30th Aug 2020

      After ordering another companies Y-Bridge and having an unsuccessful install due to poor craftsmanship, fit and finish, I reached out to Scott at SDP and told him my situation. Scott was very helpful and sincere about my situation and went to work making me a Y-bridge kit for my LMM. These are made to order! When I recieved the Y-Bridge from SDP, I knew this was a Top-notch product, fitment and quality is second to none. Install was a breeze, the two-piece studded design is awesome and allows room to work. Would definitely recommend to anyone who is considering a Y-Bridge install.

      3” y-bridge

      Posted by Nelson Logan on 23rd May 2020

      It’s amazing how much more power it produced the best $710 I’ve ever spent planning on getting the 4” cold air intake with filter in the upcoming weeks

      Exactly what i needed

      Posted by BG on 12th Jul 2018

      This kit comes with everything you need and is beyond high quality. My kit did come with the required gaskets, unlike stated in a post below. Thanks to Scott and team for answering my endless questions throughout the process. Note: The supplied instructions could be more detailed but this is by no means an amateur level install. The interweb has a good amount of install support too.
