Product Knowledge
Are new Y-bridge gaskets included with the bridge?
We do not include new Y-bridge gaskets with the Y-bridge. We recommend reusing the factory gaskets as long as they are not damaged to make installation easier.
Is this just a plug-and-play fit from stock?
I have a 2017 chevy 2500hd with rear airbags. Will the 70inch traction bars still work with the airbags installed?
Yes however
Do these up pipes match up to the PPE performance exhaust manifolds? I installed your entire bundle kit a few months back, and it's awesome. But would like to install new manifolds.
No, as our up-pipes are made to work with the factory style mounting.
I received this filter in your bundle kit, and it does not appear oiled. If it is pre-oiled, as the product title suggests, what oil should be used, moving forward, and do you have a cleaner you recommend as well? Thanks!

Installation Help
When installing the traction bars, should the rear wheels be off the ground with rear leafs at full sag or wheels on the ground and leaf springs supporting the weight at a natural stance?
It is recommended when installing our traction bars.
Does it only come with one traction bar or with both of them? I think there was some slight confusion on that.
Yes it does
