Z55 Pigtail Set: rear shock adapter
2 pigtails for one rear axle, with waterproof heat-shrink crimp connectors. For our 2005-2014 Kit on 2005-2014 trucks and SUVs, and our 1997-2012 Car Kit.
The M&P USA Z55 Pigtail Set (also called our pigtail adapter set or universal adapter) converts the 2-pin rear shock plug to the standard GM large 2-pin connector, so our 2005-2014 Kit and 1997-2012 Car Kit plug in. Each set includes 2 pigtails, enough for one axle, plus waterproof heat-shrink crimp connectors. It adapts the connector only: the MagneRide bypass itself is the kit.
The most common use is the rear shocks on 2005-2014 Cadillac Escalade, ESV, and EXT, Chevy Tahoe and Suburban, GMC Yukon and Yukon XL, and 2007-2013 Avalanche LTZ, where most rear shocks have a rear-only 2-pin plug that is a different style than the front. On a rear plug with side-by-side latches the set is optional, because the 2005-2014 Kit includes an adapter for side-by-side plugs. Made in the USA by a certified veteran-owned company and backed by our lifetime warranty.
The short answer
- Converting only the rear of a 2005-2014 truck or SUV with one 2005-2014 Kit? This is the set you need.
- Ordering two 2005-2014 Kits or the 2005-2014 2-Axle Kit? The pigtails are included free, so skip this set.
- It adapts the connector only. It doesn’t bypass anything by itself, and installing it means cutting and splicing the rear wires.
- 2015 or newer SUV, or 2013 or newer car? Not needed: our 2015-2020 Kit, 2021-2023 Kit, and 2013-2018 Car Kit plug straight in. More detail in our Z55 MagneRide bypass guide.

Read before ordering
- These do not bypass anything on their own. The Pigtail Set adapts the connector so our 2005-2014 Kit or 1997-2012 Car Kit can plug in.
- Installation requires cutting and splicing: you cut off the factory connector and crimp the pigtail onto the vehicle’s wires.
- Ordering two 2005-2014 Kits or our 2005-2014 2-Axle Kit? The pigtails are included free, so you don’t need this set.
- For the 2005-2014 Kit and 1997-2012 Car Kit only. NOT for our 2015-2020 Kit, 2021-2023 Kit, or 2013-2018 Car Kit.
Do you need the Z55 Pigtail Set?
Yes, if
- You’re converting the rear axle of a 2005-2014 truck or SUV with one 2005-2014 Kit, and your rear shock has the rear-only 2-pin plug.
- Your 1997-2012 GM car’s shock connector doesn’t match the connector on our 1997-2012 Car Kit (for example, some Buick LaCrosse and early Cadillac Seville models).
No, if
- You’re ordering two 2005-2014 Kits or our 2005-2014 2-Axle Kit: the pigtails are included free.
- Your front connectors match our kit: the front on 2005-2014 trucks and SUVs generally plugs straight in. Your rear plug has side-by-side latches: the adapter included with the 2005-2014 Kit works instead.
- You have a 2015 or newer SUV or a 2013 or newer car: our 2015-2020 Kit, 2021-2023 Kit, and 2013-2018 Car Kit plug straight in.
Message us first: 2000-2004 trucks and SUVs, and any older or unusual plug, such as a round connector. This set can adapt those too. Send us a photo of your plug before you order.

How to install the Pigtail Set
- 1Cut off the factory connector. With the vehicle off and safely raised, unplug the rear shock connector and cut it off, leaving as much wire as possible on the vehicle side.
- 2Strip the wires. Strip a short length of insulation from the vehicle’s two wires and the pigtail’s two wires.
- 3Crimp. Join each pigtail wire to a vehicle wire with the included heat-shrink crimp connectors and crimp them firmly.
- 4Seal. Heat each connector until it shrinks tight and seals.
- 5Plug in the simulator. Plug our shock simulator into the pigtail’s GM 2-pin connector until it clicks, then mount it to a metal surface, away from the exhaust.

Frequently asked questions
Do I need the Pigtail Set?
Usually only for the rear of 2005-2014 trucks and SUVs, where the rear 2-pin connector differs from the front, or for 1997-2012 cars whose connector doesn’t match our 1997-2012 Car Kit. Send us your year, make, and model if you’re not sure.
Are the pigtails included with the 2005-2014 Kit?
Yes, when you order two 2005-2014 Kits (front and rear), we include the pigtails free. They also come free in our 2005-2014 2-Axle Kit. Order the Pigtail Set separately only if you’re converting the rear axle with a single kit.
Will these work with my 2015-2020, 2021-2023, or 2013-2018 Car Kit?
No. The Pigtail Set is only for 2005-2014 Kit and 1997-2012 Car Kit connectors, used with our 2005-2014 Kit and 1997-2012 Car Kit.
Do I have to cut wires?
Yes. You cut off the factory connector and crimp the pigtail onto the vehicle’s wires with the included waterproof heat-shrink crimp connectors. You’ll need a wire stripper, crimping tool, and heat gun.
Can I use these alone to bypass my shocks?
No. The pigtails only adapt the connector. You still need our 2005-2014 Kit or 1997-2012 Car Kit.
How many pigtails come in a set?
Two, enough for one axle (both rear shocks).
Not sure you need the pigtails?
Use Find My Kit, read the Z55 guide, or send us your year, make, and model and a real person will tell you what to order.
