The Trail Boss Trap: How to Properly Lift a Silverado That Is Already Lifted
Share
You proudly own a Silverado 1500 Trail Boss (or a ZR2).
It came from the factory with a highly tuned 2-inch lift, Rancho or Multimatic DSSV shocks, and a highly aggressive stance.
But like most truck owners, you want more. You want to sit 6 inches in the air and run massive 35-inch mud terrains.
So, you go online and buy a generic "4-Inch Lift Kit," utilizing standard truck math:
2" (Factory Lift) + 4" (New Kit) = 6" Total Lift.
Wrong.
Lifting a Trail Boss is not simple addition.
Most standard lift kits are engineered specifically for the base Silverado suspension geometry. If you try to stack a standard spacer kit directly on top of your factory-lifted strut, you will dangerously over-extend your upper ball joints and absolutely destroy your CV axles the first time you hit a pothole.
To safely go higher, you typically have to completely replace the factory lift components, not blindly add to them.
The "Plus 2" Logic: A premium "4-inch Kit" from BDS Suspension designed specifically for a Trail Boss actually provides about 2 inches of new lift, resulting in the exact same final height as a "6-inch Lift" on a standard Silverado LT.
In this guide, we break down the highly confusing math of lifting a Trail Boss or ZR2, and show you exactly which premium kits allow you to keep your suspension geometry safe while gaining the altitude you crave.

Frequently Asked Questions (Lift Kits)
Can I easily fit 35-inch tires with a 3.5" or 4" lift?
Yes, but you must watch your wheel offset.
A premium 3.5-inch to 4-inch kit (like those from Zone Offroad or BDS) can comfortably clear a 35x12.50 tire, but you usually need to stick to a wheel with a high-positive offset (+18mm to 0mm).
The Rub: If you use a -12mm or -24mm "deep dish" wheel, the wider scrub radius will cause the tire to aggressively rub the front bumper valance and rear mud flap area, requiring you to trim the plastics.
What happens if I put a standard lift kit on my High Country?
Severe Suspension Errors.
The High Country uses Adaptive Ride Control (ARC), which actively changes shock stiffness on the fly based on sensor position. A standard lift kit changes the physical ride height, which entirely confuses the position sensors.
Result: The truck's computer assumes the suspension is broken and puts the electronic shocks into "Full Stiff" safety mode. The ride will be bone-jarring, and you will have a permanent "Service Suspension" light on the dash. Always buy an ARC-compatible kit.
Does a BDS Lift Kit really have a lifetime warranty?
Yes, the "No Fine Print" warranty is real.
BDS Suspension is famous in the off-road industry for their guarantee: "Use it, abuse it. If you break it, we replace it." If you physically snap a BDS control arm or crossmember while out on the trail, they will send you a new one. It gives you absolute peace of mind when pushing your heavy Silverado to the limit.
