R&P Service InsightLeaf springs are wear items in trailer suspension systems. Repeated loading, road shock, corrosion, and uneven weight distribution can reduce spring arch and cause the trailer to sit low or ride unevenly.
- Measure First: Confirm spring length, width, eye size, and slipper-end configuration before ordering.
- Replace in Pairs: Replacing only one spring can leave the suspension uneven if the opposite spring is worn.
- Inspect Hardware: Check hangers, equalizers, bolts, bushings, and U-bolts during spring replacement.
Compatibility: Best matched by part number, spring length, spring width, eye diameter, slipper-end style, and hanger/equalizer layout.
Vehicle / System Fit: Trailer slipper spring suspension systems using a 2" wide, 26-1/8" slipper spring with 4,000 lb spring capacity.
Installation Notes: Support the trailer safely, unload the suspension, and inspect related suspension components before installing new springs.
Performance Insight: Properly matched springs help restore trailer ride height, suspension travel, and balanced load support across the axle.
Brand & Fitment NoteSelling Brand: R&P Carriages / Need A Trailer Part suspension component listing.
Application Reference: Axle rating and trailer type references are application guides only. Final fitment must be confirmed by measurement and suspension layout.
What This Means: This listing is for one 1403T3 slipper spring, not a complete suspension kit.
Before Ordering: Verify spring dimensions, hanger configuration, axle capacity, and whether additional hardware is needed for installation.
R&P Repair InsightA flattened, cracked, shifted, or fatigued leaf spring can affect trailer ride height, tire clearance, axle alignment, and load balance. When replacing slipper springs, inspect the entire suspension system rather than only the failed spring.
- Spring Condition: Look for broken leaves, sagging arch, rust separation, or signs of overload.
- Mounting Points: Inspect hangers and equalizers for elongation, cracking, or uneven wear.
- Hardware Check: Confirm the correct bolts, bushings, U-bolts, tie plates, and nuts are in good condition or replaced as needed.
Multi-leaf spring construction designed to support trailer axle load and help absorb road shock during travel.
4,000 lb Spring CapacityRated for 4,000 lbs per spring when properly matched to the suspension system and trailer application.
Common Heavy-Duty Trailer FitCommonly used on trailers equipped with 8,000 lb axles where the spring dimensions and hanger layout match.
Nylon Eye Bushing InstalledIncludes a nylon bushing in the spring eye for the mounting point. Confirm bushing size and hardware compatibility before installation.
