About Belltech
Belltech develops lowering systems and dampers around application-specific suspension geometry. Its Street Performance shocks use matched compression and rebound tuning, low-friction internal components, and protective seals to balance ride quality with improved chassis control.
Related Parts
- No internal product is linked because the companion rear shock, springs, and lowering components must match the exact model, trim, drivetrain, and intended ride height.
FAQ
What is the 2212DG?It is one rear Belltech Street Performance shock for the supported Chevrolet SSR, Trailblazer family, and GMC Envoy family applications.
Is this shock sold as a pair?No. The manufacturer lists a unit of measure of each. Most rear installations require two shocks, ordered individually.
Does this shock lower the vehicle?No. A shock controls suspension motion; lowering requires the correct springs or other suspension components for the vehicle.
What are the compressed and extended lengths?Belltech lists a 14-inch compressed length and a 22.5-inch extended length.
Is it intended for the front or rear?It is a rear-position shock with eyelet mounts at both ends.
Does it fit every Trailblazer or Envoy?No. Match the exact model year, model, trim, drivetrain, and suspension configuration to the fitment table and current Belltech catalog.
Can it replace one worn shock only?A single unit can be purchased, but shocks on the same axle are generally serviced as a matched pair unless the vehicle and component inspection supports another approach.
What should be checked after installation?Verify fastener torque, bushing seating, brake-hose and wiring clearance, full suspension travel, and the absence of leaks or contact before normal driving.
Installation Instructions
- Confirm the exact vehicle, rear position, ride-height configuration, and Belltech 2212DG before supporting the vehicle.
- Read the current Belltech instructions and the vehicle service procedure, then safely raise and support the chassis and rear axle.
- Remove the original rear shock without allowing the axle, brake hoses, or wiring to overextend.
- Compare the compressed and extended lengths, eyelet widths, bushing sleeves, and mounting hardware before installation.
- Install the shock in the correct orientation and torque the upper and lower fasteners with the suspension at the condition specified by Belltech and the vehicle manufacturer.
- Cycle the suspension, verify clearance and bushing alignment, road-test carefully, and recheck the fasteners after the initial drive.
