ReadyLIFT 2 inch front leveling kit with tubular control arms

What are you paying extra for?

The control arms—not the two inches.

ReadyLIFT 66-1921 is the complete-package choice in this group: a fixed 2-inch front level plus tubular upper control arms. Rough Country 35400 reaches the same headline height with a simpler spacer kit, while Bilstein 24-232203 trades the all-in-one package for ride-height adjustment and monotube damping.

We read the owner threads; the install note to check first is possible spacer-to-strut-stud contact during installation. Notes below.

The public evidence is useful but thin: one long-term owner reported no trouble, while a separate install thread raised a spacer-to-strut-stud clearance concern. Treat both as configuration-dependent owner reports, not a reliability score. On the positive side, a two-year follow-up reported trouble-free use on the owner's truck. (Two-year owner follow-up). The concern to inspect: another owner documented possible spacer-to-strut-stud contact during installation and asked the community to check the setup. (Install-clearance discussion). Anecdotes are attributed and never treated as a reliability score.

Choose it, pass, or verify

A common 5th-gen Ram 1500 front leveling kit that pairs a 2 inch front level with replacement upper control arms for non-air-suspension trucks.

Choose it if

  • Best fit for owners who want a more complete front leveling package with upper control arms included.
  • Confirm non-air-suspension fitment, installer comfort, brake-line routing, and alignment before ordering.
  • Compare seller price and stock, but do not choose this only on price if the truck needs simpler spacer-only hardware.
  • Use for new-body Ram 1500 trucks when the retailer fitment selector confirms the exact cab, drive, and suspension package. The 2022 Big Horn 4x4 route is inside this checked body style.

Pass if

  • The ReadyLIFT 2 inch front leveling kit with tubular control arms is not the right choice when your truck falls outside 2019-2026 Ram 1500 new-body trucks, or its trim, engine, and package cannot be matched to the documented application.
  • Pass when this exclusion applies: Ram 1500 Classic / DS old-body trucks
  • Choose another kit when the truck needs more height, rear-load support, adjustable damping, or hardware this package does not include.

Verify

  • Exact body style and trim
  • Air-suspension and factory pre-lift status
  • Alignment and electronic safety-system calibration after install
  • Year/model/trim match matters here: Big Horn 4x4 non-air-suspension trucks can be checked against this range, but Classic, air-suspension, factory pre-lift, and conflicting off-road packages must be filtered out before checkout.
Workshop & DIY Guidelines

ReadyLIFT 2 inch front leveling kit with tubular control arms Installation & Fitment Protocol

Front leveling kits work by adding a top-mount or preload spacer above the factory coilover strut, neutralizing the built-in factory rake. Because independent front suspension operates on a motion ratio (typically ~1:1.5 to 1:2.0), the physical spacer thickness is smaller than the resulting ride height gain. A 1.25-inch thick spacer produces approximately 2.0 inches of net lift at the wheel hub.

Install Difficulty

Shop & Bench Specs

Difficulty: Moderate (3/5)

Estimated Install Time: 2.5 – 4.0 hours (DIY Garage) / 1.5 – 2.5 hours (Pro Shop)

Required Tools

Installation Equipment

  • Heavy-duty hydraulic floor jack (3-ton+) & matching safety jack stands
  • Calibrated torque wrench (50–250 lb-ft range)
  • Metric socket & combination wrench set (15mm, 18mm, 19mm, 21mm, 24mm)
  • Ball joint separator / tie rod puller tool (prevents boot tearing)
Post-Install Safety

Post-Install Protocol

  • Mandatory 4-wheel computer alignment within 50 miles of install to set toe and camber.
  • Re-torque all chassis fasteners, strut top nuts, lower control arm bolts, and wheel lug nuts at 50 and 500 miles.
  • Re-aim headlight vertical cutoffs downward to compensate for raised front nose height.

Wear Triggers & Maintenance Checks

  • Upper ball joint binding at full suspension droop if lift exceeds 2.25 inches without aftermarket control arms.
  • Accelerated inner tire edge wear if alignment toe-in is not corrected post-installation.
  • Front CV axle boot rib-rubbing and grease weeping under sustained 4WD high-speed operation.

Chassis Fitment Context

Ram 1500 DT uses a coilover strut with an IFS motion ratio of ~1:1.68. The rear suspension features a 5-link coil setup that maintains ride comfort but requires careful rear spacer height selection to prevent rear spring unseating at full droop when extending rear shocks.

The 2019 model year split Ram 1500 into two distinct architectures: the continuing 4th Gen Ram Classic (DS platform, 5-lug) and the all-new 5th Gen (DT platform, 6-lug). In 2025, Ram refreshed the DT architecture with the 3.0L Hurricane Twin-Turbo inline-six powertrain, updated front fascia, and electric architecture changes, while preserving the 6x139.7 wheel fitment.

Pre-Installation Unboxing Verification Checklist

Step 01: Confirm Physical SKU & Labeling

Inspect outer box label against your order invoice and the manufacturer part number shown here before opening hardware bags.

Step 02: Dry-Fit & Hardware Inventory

Unpack fasteners, brackets, and instructions. Perform a preliminary dry-fit check against the vehicle before removing factory components.

Step 03: Review Torque & Thread Requirements

Identify critical torque values and whether thread locker (Blue Loctite) or anti-seize compound is required by the manufacturer.

Step 04: Plan Post-Install Calibration

For suspension, steering, or lighting parts, schedule a professional alignment and verify forward-facing ADAS sensor calibration.
