1. Daystar Polyurethane Coil Spring Spacer (KU09011BK): Best Overall
Daystar’s KU09011BK is a top choice for those seeking a reliable 1.5-inch lift. In our evaluation, the polyurethane formulation shows excellent resistance to deformation and cracking, based on owner feedback over extended use. The integrated alignment nibs simplify installation, ensuring the spacer stays centered. However, some users report occasional squeaking after months of use, which can be mitigated with silicone grease.
This spacer is best for Jeep Wrangler and truck owners who want a durable, no-nonsense lift. Skip it if you prefer a completely silent ride or need a spacer for a vehicle with a complex coil spring setup that requires custom fitment.
- Precision-molded polyurethane resists compression set and cracking
- Includes integrated alignment nibs for proper positioning
- Corrosion-resistant hardware included
Pros: Excellent durability and long-term performance; Easy installation with basic tools
Cons: May squeak over time without lubrication
2. Rough Country Leveling Lift Spacer (Rough Country 1000): Best Value
Rough Country’s spacer is a popular budget-friendly option for leveling Chevy and GMC trucks. Our research shows that the steel construction offers good rigidity, but the powder coating can chip off, leading to potential rust in harsh environments. Owner feedback indicates that installation is straightforward, but some notice a firmer ride after installation.
This spacer is ideal for truck owners on a budget who want a quick leveling solution. Skip it if you live in areas with heavy road salt or if ride comfort is your top priority.
- Heavy-duty steel construction with black powder coat finish
- Designed to level front end of 2WD/4WD trucks
- Includes all necessary mounting hardware
Pros: Affordable price point for a 2 inch lift; Simple bolt-on installation
Cons: Steel can rust if coating is scratched; May stiffen ride slightly
3. Supreme Suspensions Polyurethane Coil Spring Spacer (SS-1003): Premium Pick
Supreme Suspensions delivers a premium polyurethane spacer that impressed us in our evaluation. The high-density material and CNC machining ensure a precise fit, and the lifetime warranty reflects confidence in durability. Based on owner feedback, the spacer maintains its shape and does not squeak when properly installed. The UV stabilizers also help prevent degradation from sunlight.
This is the best choice for Ford F-150 owners who want a high-quality, long-lasting spacer and are willing to invest a bit more. Skip it if you need a larger lift height or are on a strict budget.
- High-density polyurethane with UV stabilizers
- Precision CNC-machined for exact fit
- Lifetime warranty against defects
Pros: Outstanding build quality and fit; Lifetime warranty provides peace of mind
Cons: Premium price compared to steel alternatives
4. Pro Comp Suspension Coil Spring Spacer (Pro Comp 13120): Most Durable
Pro Comp’s aluminum spacer is built to last. In our comparison, the billet aluminum and anodized finish offer superior corrosion resistance, making it ideal for off-road and salt-prone environments. Owner feedback highlights that it maintains its integrity even under harsh conditions. However, the 1 inch lift is modest, and the price per inch of lift is higher than polyurethane options.
This spacer is perfect for Jeep JK owners who prioritize durability and off-road capability over maximum lift. Skip it if you need a 2+ inch lift or want a more budget-friendly option.
- Billet aluminum construction for corrosion resistance
- Anodized finish for added protection
- Designed for off-road use
Pros: Extremely durable and rust-proof; Lightweight compared to steel
Cons: Only 1 inch lift may not be enough for some; Higher cost per inch of lift
5. Zone Offroad Coil Spring Spacer (Zone Offroad ZONFRCS20): Best for Off-Road
Zone Offroad’s spacer is designed with off-road enthusiasts in mind. The dual-durometer polyurethane aims to absorb impacts, and the grease grooves help reduce squeaking. Based on owner feedback, it performs well on trails, but some users experienced fitment issues on specific Toyota model years, requiring minor modifications. The material, while effective, may not withstand extreme rock crawling as well as aluminum.
This is a good choice for Toyota 4Runner and Tacoma owners who do moderate off-roading. Skip it if you have a late-model vehicle or if you need a spacer that can handle heavy abuse.
- Dual-durometer polyurethane for impact absorption
- Includes grease grooves to minimize squeaking
- Evaluated for off-road use
Pros: Good impact absorption for rough terrain; Grease grooves help reduce noise
Cons: Some fitment issues reported on certain Toyota years; Not as durable as aluminum in extreme conditions
6. Tuff Country Coil Spring Spacer (Tuff Country 1000): Budget Pick
Tuff Country’s spacer is a no-frills option for budget-conscious Ram 1500 owners. Our research indicates that while the steel is functional, the paint finish is prone to chipping, leading to rust over time. Owner feedback mentions that installation is straightforward, but some report a slight misalignment that requires adjustment. The spacer provides a basic 1.5 inch lift, but ride quality may suffer slightly.
This spacer is suitable for those on a tight budget who need a temporary or minimal lift. Skip it if you want long-term durability or a precise fit.
- Economical steel construction
- Black paint finish
- Simple design for basic leveling
Pros: Very affordable; Easy to install
Cons: Paint can chip and rust; Less precise fitment than premium options
7. Spyder Off-Road Coil Spring Spacer (Spyder Off-Road 1000): Lightweight Option
Spyder Off-Road offers a lightweight nylon composite spacer that is one of the most affordable options. In our evaluation, the material is easy to install due to its low weight, but durability is a concern. Owner feedback indicates that the nylon can crack or deform under heavy loads or in cold weather. The universal fit design may not sit perfectly in all coil springs, leading to potential alignment issues.
This spacer is best for light-duty use on smaller trucks or SUVs where maximum lift and durability are not required. Skip it if you plan to carry heavy loads or off-road frequently.
- Lightweight nylon composite material
- Universal design with multiple bolt patterns
- Includes hardware for basic installation
Pros: Very lightweight and easy to handle; Low cost
Cons: Nylon may crack under heavy loads; Universal fit can lead to poor alignment
Frequently Asked Questions
Are coil spring spacers safe for daily driving?
When installed correctly and within the vehicle’s design limits, coil spring spacers are generally safe for daily driving. However, they can alter suspension geometry, potentially affecting ride comfort and handling. We recommend using spacers that are designed specifically for your vehicle model and staying within a 2-inch lift to minimize risks.
Will coil spring spacers void my vehicle warranty?
It depends on the manufacturer and the specific warranty terms. Some automakers may void suspension-related coverage if aftermarket spacers are installed. We advise checking your warranty documentation or consulting with your dealer before installation.
How much lift can I get from coil spring spacers?
Most coil spring spacers provide between 1 and 2.5 inches of lift. Going beyond 2 inches often requires additional modifications like longer shocks or control arms to maintain proper alignment and avoid excessive wear.
Do I need an alignment after installing coil spring spacers?
Yes, we strongly recommend a professional alignment after installation. Spacers can change the vehicle’s ride height, affecting camber, caster, and toe angles. An alignment ensures even tire wear and safe handling.
Can I install coil spring spacers myself?
Installation is possible for experienced DIYers with proper tools and a safe workspace. However, compressing coil springs is dangerous. If you are not confident, we recommend professional installation to avoid injury and ensure correct fitment.
