If you're in the market for suspension upgrades, you've likely come across ASP suspension parts. This review covers the key product lines, what to look for when buying, and how to match components to your vehicle and driving needs. Whether you're lifting a truck for off-roading or improving on-road handling, understanding the options helps you make a sound investment.
Overview of ASP Suspension Parts
ASP manufactures a range of suspension components including lift kits, shocks, struts, control arms, coil springs, and track bars. Their parts target trucks, SUVs, and off-road vehicles. The company is known for offering complete kits and individual components at competitive prices. Many enthusiasts choose ASP for budget-friendly builds without compromising basic reliability.
Key Product Categories
Lift Kits
ASP offers leveling kits and complete lift systems in various heights (1.5 to 6 inches). Kits typically include spacers, blocks, or new coil springs depending on the vehicle. For example, a 3-inch lift for a Jeep Wrangler might come with front strut spacers, rear coil spring spacers, and sway bar end links. Some kits include shock extensions or longer shocks.
Shocks and Struts
ASP shocks are available in gas-charged and reservoir styles. Gas-charged shocks provide consistent damping for daily driving, while reservoir models handle extended off-road use by preventing fade. Struts are assembled units for vehicles with McPherson front suspension, sold as complete assemblies or with separate coils.
Control Arms
Upper and lower control arms from ASP are built from steel or aluminum. Steel arms are more durable for rock crawling, while aluminum reduces weight for better ride quality. Many come with replaceable bushings and ball joints, extending service life.
Coil Springs and Leaf Springs
ASP manufactures progressive-rate coils that balance comfort and load capacity. Leaf springs are available for rear applications, with options for add-a-leaf or full replacement packs.
What to Consider Before Buying ASP Suspension Parts
Vehicle Compatibility
ASP parts are designed for specific makes and models. Double-check application guides on packaging or manufacturer websites. Using incorrect parts can compromise safety and handling. Note that some kits fit multiple years, but minor differences in steering or brake components may require additional adapter parts.
Intended Use
Match the parts to your driving style.
- Daily driver / pavement only: A leveling kit with gas shocks is sufficient. Avoid overly stiff springs that degrade ride comfort.
- Light off-road / trails: A 2–3 inch lift with monotube shocks and extended sway bar links works well. Control arms may need upgrading if alignment becomes difficult.
- Heavy off-road / rock crawling: A 4–6 inch lift with reservoir shocks, adjustable control arms, and a track bar relocation bracket is necessary. ASP’s heavy-duty options suit these demands.
Lift Kit Components
Complete lift kits from ASP include all necessary hardware: shock mounts, bump stop extensions, brake line brackets, and alignment cams if required. Partial kits may only include spacers, requiring you to source shocks separately. Evaluate what is included to avoid hidden costs.
Comparing ASP Parts to Other Brands
ASP competes with brands like Rough Country, Skyjacker, Billstein, and ReadyLIFT. While ASP often comes at a lower price point, material quality and finish may not match premium brands. However, for many budget-conscious builds, ASP provides adequate performance. Welds on control arms are generally clean, and powder coating resists corrosion for several seasons.
Shock damping characteristics tend to be firm, which is acceptable for off-road but may feel harsh on washboard roads. Consider pairing ASP springs with aftermarket shocks if you prioritize comfort.
Installation Tips and Common Issues
Tools Needed
Basic hand tools, a spring compressor (for coil-over or strut assemblies), jack stands, and a torque wrench. Lift kit installation can take 4–8 hours for a DIYer with experience.
Potential Fitment Problems
Some users report misaligned bolt holes on control arms or incorrect bushing hardness. Inspect parts before installation. ASP customer service can send replacements if there is a defect. Always verify part numbers against your vehicle's specifications.
Alignment After Lift
A lift of 2 inches or more often requires cam bolts or adjustable control arms to correct caster and camber. ASP sells alignment kits separately. Plan for a professional alignment after installation.
Maintenance and Longevity
ASP parts generally last 2–5 years depending on usage. Bushings may squeak after exposure to mud or salt; regular cleaning and lubrication extend life. Check ball joints for play during oil changes. Replace worn components promptly to avoid premature tire wear.
Where to Buy ASP Suspension Parts
ASP parts are sold through off-road retailers, truck accessory shops, and many online stores. Compare prices across vendors, but avoid suspiciously low deals. Some sellers offer free shipping or bundle discounts. Check return policies in case of fitment issues.
Practical Recommendations
For a first-time suspension upgrade on a daily-driven truck, start with a small leveling kit and gas shocks from ASP. This improves stance and tire clearance without radical changes. If you plan to off-road regularly, invest in a complete kit with control arms and upgraded shocks. Remember that suspension modifications affect the entire vehicle – plan for larger tires, possibly speedometer recalibration, and driveline changes if lifting over 3 inches.
ASP suspension parts are a solid choice for those on a budget who understand their limits. They deliver reliable performance for moderate use but may not satisfy extreme demands. Combine ASP components with careful planning and regular maintenance to get the most from your suspension system.
Final Verdict
Are ASP suspension parts worth it? Yes, for the price-conscious enthusiast who does their homework on fitment and realistic expectations. For extreme off-road abuse, consider higher-end brands. But for everyday upgrades, ASP offers functional parts that get the job done without breaking the bank.
