Match support to your load: EZ for occasional duty, LP-25 or LP-35 for steady weight, Silent Support for quiet refinement, Contact Helpers to wake factory overloads, and add a Hellwig sway bar to cut roll.
Start with two facts you can trust: how much weight you carry and how often you carry it. Everything good with Hellwig comes from matching support to reality. If your truck sits level most days but sags for a few road trips a year, EZ-series helper springs are your smartest starting point. They bolt on with hand tools, add adjustable support above the leaf pack, and let you fine tune preload so the rear sits right with a trailer or vacation cargo. On Monday after you unload, the vehicle goes back to its normal, friendly ride.
If your world includes steady weight, step into the progressive families. LP-25 is a sweet spot for trucks and vans that carry tools, camping builds, or a couple of dirt bikes often. LP-35 brings more authority for heavier beds or one ton platforms that see real payload. Progressive support means the spring stiffens as load grows, so you don’t get a lazy second bounce after speed humps and you do keep headlights aimed where they belong. When product pages call for a separate mounting kit, add it at checkout so the install stays painless.
Want a refined feel on patchy concrete. Silent Support System helper springs mount over the axle with bushings that hush little noises. You still get real load support, but your passengers won’t hear the rear working through seams and joints. It’s an easy recommendation for family SUVs and people haulers that also carry gear.
If your truck has factory overloads that engage late, Contact Helper Springs bring that help in earlier. The difference shows up when you hitch a small trailer or load stone in the bed. The rear stays flatter right away, braking feels more natural, and the steering stops going light on crowned lanes. It’s a small change that pays off every time you work the vehicle.
Roll control is the final piece. A level rear solves sag, but a tall load still leans. A Hellwig sway bar trims body roll so you can steer once and relax. On long on-ramps and quick transitions, the bar keeps the chassis from heaving side to side. With helper springs and a sway bar together, the wheel grows calm and the cabin stays quiet.
Finish well so good parts feel great. Stage hardware and torque specs before you wrench. Mock up the helper spring stack on the leaf pack, align the crossbars, then tighten evenly. Set the vehicle back on its tires and torque at ride height. Re-aim headlights after any change in rear attitude. Set tire pressures cold based on the day’s weight. Book a four-wheel alignment if the steering wheel sits off center. Take a short test loop with one rough patch, a long sweeper, and a mile of highway. If the rear still porpoises after dips, add a touch of preload, then repeat the loop. Keep the setting that felt best in a quick note with the load you carried so next time is fast.
Here’s a quick cheat sheet you can save.
-
EZ-series: occasional loads and weekend towing.
-
LP-25: frequent payloads on half ton and three quarter ton trucks or vans.
-
LP-35: heavier duty support for one ton and steady weight.
-
Silent Support: quieter, over-axle mounting with tunable help.
-
Contact Helper Springs: earlier engagement for factory overloads.
-
Hellwig sway bar: reduce roll with trailers, campers, and tall cargo.
