1999-2014 GMC Yukon / Yukon XL Rear Adjustable Control Arms | Heavy-Duty Suspension Upgrade








Factory rear control arms on the GMT800/GMT900 Yukon are fixed-length — correct at stock height, but once you add lift, pinion angle drops, driveline vibration increases, and U-joint wear starts. The Apoc Industries Rear Adjustable Control Arms restore proper rear suspension geometry from stock to 6" of lift, keeping your Yukon or Yukon XL handling correctly no matter how your build evolves.
Fits 1999–2014 GMC Yukon and Yukon XL. Includes all 4 arms. Built in the USA.

What all comes with Apoc control arm kits?
Complete Kit – Ready to Install:
Each kit comes as a full set of four control arms — including two upper arms and two lower arms — fully assembled and ready for installation. You can reuse your factory hardware for mounting, or upgrade to new hardware if it is included or added to your order. Our goal is to make your installation as smooth and hassle-free as possible.
Premium Bushings – Built for Life:
Apoc Industries backs our bushings with a Lifetime Warranty for lasting confidence. We use only the highest quality polyurethane (PTMEG-based) in all Apoc products.
PTMEG polyurethane offers superior articulation and a firmer, more responsive feel — without the harshness commonly found in solid joints like heims or flex joints.
These bushings are ideal for daily driving while providing excellent durability and performance for moderate off-road use.
Adjustable Length for Precise Handling:
Apoc control arm kits are designed with flexibility in mind. They are stock length when fully collapsed and up to 2.5 inches longer when fully extended, giving you plenty of adjustability to fine-tune your truck’s suspension geometry and handling. Whether you’re leveling, lifting, or optimizing alignment, our arms provide the range needed for a perfect setup.
Lifetime Warranty Polyurethane Bushings
Apoc Industries' high-performance polyurethane bushings are backed by a lifetime warranty and engineered for durability you can count on. Easily rebuildable with basic tools, they deliver a firm, responsive ride without the hassle—made for daily drivers and built for the long haul.

FAQ'S
A: If your Tahoe came with factory air ride suspension, you’ll need trailing arms with sensor tabs to retain proper ride height control. If your vehicle doesn’t have factory air ride, the standard arms without tabs are all you need. If you’ve added aftermarket air ride, you do not need the sensor tabs—those systems are typically self-contained and do not rely on factory sensor locations.
💡 How to Tell If You Have Factory Air Ride:
Look for a small sensor arm connected to the rear trailing arms, or check your RPO code sticker (typically in the glove box or driver’s door jamb) for codes like Z55 or Z95.
A: Absolutely. Our trailing arms are fully adjustable to accommodate stock height up to 6" of lift, allowing you to dial in proper axle placement and suspension geometry.
We supply instruction and resources for establishing correct lengths.
A: Yes. Apoc trailing arms are designed to work seamlessly with most aftermarket lift kits, and performance shocks used on lifted GM trucks (Avalanche) and SUV's
For PTMEG (polytetramethylene ether glycol) polyurethane bushings, the best grease is a silicone-based lubricant with PTFE (polytetrafluoroethylene) additives. Here’s why and what to consider:
Why Silicone-Based with PTFE?
: PTMEG polyurethane is resistant to petroleum-based products, but silicone-based grease is preferred as it won’t degrade the material and is explicitly recommended for polyurethane bushings.Tackiness
: PTFE additives lower the coefficient of friction and are waterproof, ensuring long-lasting lubrication and quiet operation.
: Silicone-based grease repels water, protecting bushings from corrosion and maintaining performance in wet conditions.

Custom Polyurethane Bushings
Built for performance and practicality, our custom polyurethane bushings deliver a firmer, more responsive suspension feel while still allowing enough flex for a comfortable ride. Designed with DIY rebuilds in mind, these bushings can be easily serviced at home using basic hand tools—no press required. Durable, reliable, and user-friendly, they’re made to enhance handling and stand up to long-term use without sacrificing everyday drivability.
Serviceable 1/4"-28 Grease Zerks for Easy Maintenance
Our bushings are equipped with 1/4"-28 grease zerks for easy maintenance and long service life. These fittings are a common size, making them easy to service or replace with standard parts from any auto parts store. Designed for convenience, they allow quick re-greasing without disassembly to keep your suspension performing at its best.
Presicion Fit
Instead of using a one-size-fits-all approach, Apoc meticulously machines each arm to fit individual vehicles using precise tolerances and factory specifications. This guarantees a perfect and lasting fit, unlike other companies that rely on shims and generic components. Trust the expertise and quality of Apoc for your vehicle's needs.
Extra Thick tubing
Apoc opts for thick wall tubing, which is significantly stronger than stock and one of the toughest on the market.
