50 Caliber Racing 4-Point Harness for Bucket Seats — Quick-Release, Heavy-Duty Polyester (Black)

50 Caliber Racing's 4-point harness is a heavy-duty, quick-release safety belt designed to replace factory lap belts and secure drivers and passengers in bucket seats during off-road and racing use.

If you want a visible improvement in occupant restraint without a complicated installation, this 4-point harness offers durable webbing, a fast-release buckle and adjustable straps that fit most 17"–22" bucket seats. Built for UTVs, RZRs, race cars and custom rigs, it balances comfort, range of adjustment and compatibility with universal mounting points—while offering nine color choices to coordinate with your vehicle.

How does the quick-release buckle speed up exits?

The harness uses a push-button quick-release mechanism that lets you free the lap and shoulder straps in one motion. That minimizes fumbling during exits and keeps timed egress predictable under stress.

• Single central push-button release for rapid unbuckling
• 2" lap belt width for stable hold across the hips
• 3" shoulder straps distribute load across the chest and shoulders
• Steel hardware ensures the buckle stays reliable under repeated use

Will this fit my bucket seat and body size?

The shoulder straps are designed to telescope from approximately 20" up to 70", and the harness is intended for standard 17"–22" wide bucket seats. Multiple adjustment points make it simple to tailor the fit for different torso lengths and sitting positions.

• Shoulder adjustment range: 20"–70" for small to large drivers
• Compatible with most 17"–22" bucket-seat widths without trimming
• Adjusters and sewn loops allow fine-tuning of strap tension
• Works with aftermarket seats and many stock seat configurations

What materials and construction ensure durability?

This harness is built from high-strength polyester webbing combined with steel adjusters and reinforced stitching. Those choices provide abrasion resistance, consistent load distribution and long service life when used in off-road and track environments.

• Heavy-duty polyester webbing resists wear and UV exposure
• Steel adjusters and mounting hardware for secure anchoring
• Reinforced seams at load points to reduce stretch over time
• Quality control for consistent strap length and strength per piece

How do I mount this harness across different vehicles?

The product ships with universal hardware intended to work in UTVs, RZRs, race cars and custom automotive installs. Mounting points and included fittings accommodate several common anchor configurations to simplify installation.

• Universal mounting hardware for bolt-in anchor points
• Works with floor or chassis-mounted anchor locations
• Can be adapted for roll-cage webbing mounts with proper fittings
• Installation recommended by a qualified technician for racing use

Who is this for: Drivers and passengers upgrading from a factory lap belt or basic harness who want a robust, user-friendly restraint for recreational off-roading, UTV trails, autocross and track use. It suits owners of RZRs, UTVs and race cars seeking a balance of quick egress, adjustable fit and strong materials—plus a variety of colors to match interiors or safety themes. For competitive motorsport where specific certification is required, check event rules and consider professional installation to meet those standards.
