Gabriel Load Carrier Rear Spring-Assist Shocks for Chevrolet/GMC C/K Trucks — Pair, 500 lb Support, Heavy-Duty D.O.M. Construction

Gabriel 43163 Load Carrier rear spring-assist shocks are a matched pair of heavy-duty replacement shocks that combine variable-rate coil springs with a sealed shock design to help support up to 500 lbs per pair and improve stability when towing or hauling. Gabriel has engineered ride-control products since 1907, and the Load Carrier line blends suspension spring support with conventional damping to reduce rear sag and restore ride height during sustained loads. These rear shocks are built with D.O.M. tubing, a chromed piston rod, and a leak-resistant seal to hold up under frequent towing and heavy use. They are sold as a pair and designed to fit select Chevrolet and GMC C/K-series pickup applications — always verify vehicle fitment before purchase.

How do these shocks help when towing a trailer?

The Load Carrier design adds spring-assisted support to the rear axle so the truck maintains a more level stance under continual loads. That extra support helps keep headlight aim more stable, reduces rear-end sag, and improves overall vehicle control while towing.

• Variable-rate rear coil springs supply up to 500 lbs. of support per pair (not an increase to GVWR).
• Shock damping controls rebound and compression for smoother handling under load.
• Improved ride height retention reduces sway and instability from rear-heavy loads.

Will these change my truck’s payload rating or GVWR?

No — Gabriel Load Carrier shocks provide supplemental support but do not alter the vehicle manufacturer’s payload rating or GVWR. They are intended to assist stability and ride height during loaded conditions, not to increase certified carrying capacity.

• Use the shocks to help maintain ride height when hauling, not to exceed vehicle limits.
• Always follow the vehicle manufacturer’s weight ratings and towing guidelines.
• Variable springs are measured as support, not an increase of payload certification.

What are the key construction features and how do they help longevity?

Gabriel builds these shocks with drawn-over-mandrel (D.O.M.) tubing to minimize internal wear and a chromed piston rod for corrosion resistance and consistent seal performance. A leak-resistant piston seal extends service life, and the robust coil springs are wound to provide dependable load support through repeated use.

• D.O.M. tubing reduces internal abrasion and improves durability.
• Chromed piston rod protects against rust and promotes smooth operation.
• Leak-proof piston seal helps maintain damping performance longer.

How do I confirm fitment for my Chevrolet or GMC truck?

Fitment varies by year, model, and bed configuration; always verify with a fitment tool or parts guide before ordering. The Gabriel 43163 rear shocks list compatibility with many C1500, C2500, C3500, K1500 and K2500 series trucks as a starting reference.

• Check the vehicle year, make, model, and rear mounting codes.
• Use retailer "Confirmed Fit" tools or consult OEM cross-reference numbers.
• Compare extended and collapsed lengths (25.05" extended, 15.69" collapsed) and stroke (9.36").

Who is this for? These Gabriel 43163 Load Carrier rear shocks are aimed at truck owners who frequently tow or carry heavy rear loads — boat owners, landscapers, contractors, and anyone who wants improved rear support and more consistent handling while hauling. If you need durable, service-oriented shocks built to resist leakage and corrosion, provide spring-assist support, and fit older Chevy or GMC C/K pickups, this Gabriel pair is engineered for that use. Remember to confirm exact fitment for your vehicle and adhere to your manufacturer’s weight limits.
