Complete Kit – Ready to Install:

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.

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.

Durable, reliable, and user-friendly, they’re made to enhance handling and stand up to long-term use without sacrificing everyday drivability.
Presicion Fit

Serviceable 1/4"-28 Grease Zerks for Easy Maintenance
