Frequently Asked Questions

What size lift kit should I get for my truck?

The right size depends on your goals and tire size. A 2-3 inch lift is ideal for levelling the front-to-rear rake and fitting 33-inch tires. A 4-6 inch lift provides clearance for 35-inch tires and a noticeably more aggressive stance. Lifts of 7 inches or more are built for 37-inch-plus tires and serious off-road clearance, but typically require additional modifications like extended brake lines, longer driveshafts, and upgraded steering components.

Does installing a lift kit affect towing capacity on a truck?

A lift kit changes the truck's centre of gravity and suspension geometry, which can affect stability when towing heavy loads. Most 2-4 inch lifts have minimal impact on towing when paired with the correct shocks and alignment. Larger lifts of 6 inches or more can reduce towing stability and may require additional upgrades like traction bars, sway bars, and steering stabilizers. Always check your truck's towing ratings and consult with a professional installer after lifting.

Can you install a lift kit on a truck with factory air ride suspension?

Yes — BDS Suspension and other manufacturers offer lift kits specifically designed for trucks with factory air ride, including Ram 2500/3500 and GM HD models. These kits retain the factory air ride system while adding the desired lift height. Using a non-air-ride kit on an air-ride-equipped truck will not fit correctly and can damage the factory suspension. Always select the kit matched to your exact suspension configuration.

What is the difference between a radius arm and 4-link lift kit?

A radius arm lift kit replaces or extends the factory radius arms and is typically simpler to install with fewer components. A 4-link lift kit replaces the entire front suspension linkage with four separate control arms, providing better axle articulation, improved ride quality, and more precise alignment geometry at higher lift heights. On Super Duty and Ram HD trucks, 4-link kits are the preferred choice for lifts of 6 inches and above.

Does a lift kit void your truck warranty in Canada?

Under Canadian consumer protection law, a dealer cannot void your entire warranty simply because you installed a lift kit. However, if a warranty claim is directly related to the lift kit installation — such as a driveshaft failure caused by incorrect angles after lifting — the dealer can deny that specific claim. Using a quality lift kit from BDS, ReadyLift, or Rough Country installed by a professional shop minimizes warranty risk.

What is the difference between Fox and NX2 shocks in a lift kit?

Fox 2.0 and Fox 2.5 shocks are high-performance monotube shocks with larger bore sizes, remote reservoirs (on 2.5 models), and superior heat dissipation for heavy off-road use and towing. NX2 shocks are twin-tube shocks from Zone Offroad that provide solid on-road comfort and moderate off-road performance at a lower price point. For trucks used primarily for towing, hauling, or aggressive off-road driving, Fox shocks are the stronger choice. For daily driving with occasional off-road use, NX2 shocks deliver reliable performance at a better value.
