Eibach 1300.300.0700S ERO Off-Road Coilover Spring 13in x 3in 700lb

Vehicle/Application Fitment

• Universal - this is a standalone off-road racing coilover main spring, sold by physical dimension and spring rate, not matched to any specific vehicle
• Fits coilover shock bodies or sleeves with a 3.00" inside diameter

Fitment Notes

• Spec derived from Eibach's standard part-numbering convention (Length.ID.Rate) and cross-checked against multiple confirmed sibling part numbers in the same 3.00" ID / 700 lb/in ERO off-road spring family (1200.300.0700S, 1400.300.0700S, 1600.300.0700S, 1800.300.0700S) - I did not find a retailer listing for this exact 13" length SKU, so treat the length and rate as high-confidence but not directly source-verified
• Not vehicle-specific - compatibility depends entirely on your coilover's shaft/sleeve diameter (must match this spring's 3.00" ID) and the free length your suspension travel requires (13.00")
• Part of Eibach's ERO (off-road) line rather than the standard ERS street/track race spring line - built specifically for off-road durability rather than circuit/street handling characteristics
• Sold individually
• Block height and total travel figures were not confirmed for this specific 13" length - for reference, the 14" version of this same ID/rate spring lists a 6.57" block height and 7.43" of travel, but don't assume this 13" spring matches those numbers exactly; confirm against your specific coilover before ordering

Features

• Legendary Eibach off-road durability and performance
• Made from Hi-Ten spring steel to precise Eibach tolerances
• Maximum suspension travel in combination with smallest block heights
• Each spring individually tested for rate accuracy and linearity
• Highest linearity and guaranteed spring-to-spring consistency
• Silver powder coat finish

Specifications

• Free Length: 13.00 in (330.2mm)
• Spring Rate: 700 lbs/in
• Spring Type: Linear, off-road (ERO series)
• Finish: Silver powder coat

Included Components

Product Description

The Eibach 1300.300.0700S is a standalone off-road coilover spring from Eibach's ERO line, built for the repeated high-load impacts of off-road racing rather than street or circuit duty. At 13 inches free length, a 3.0-inch inside diameter, and a 700 lbs/in rate, it's a heavy-duty spring aimed at trophy truck, UTV, and off-road coilover applications running large-bore shocks.

Eibach's off-road-specific durability testing is the differentiator from their standard ERS street/track spring line - these are built to hold dimension and rate through the kind of repeated jump and impact loading that would fatigue a standard race spring faster. The 700 lbs/in rate puts this toward the stiffer end of the range, suited to heavier vehicles or setups needing to resist bottoming out under hard compression.

As with any bare coilover spring, fitment is entirely dimensional rather than vehicle-based: your coilover's inside sleeve diameter needs to match the 3.00" ID here, and your available shock travel and target ride height need to work with a 13" free length spring. Given that I couldn't directly verify the exact block height and travel figures for this specific length, I'd recommend confirming those numbers against your coilover's spec sheet, or contacting Eibach directly, before finalizing a purchase.
