If you own a Honda Integra Type R (DC5) or its North American counterpart, the Acura RSX Type S, you know the suspension is a key part of the driving experience. Whether you need to replace worn components or upgrade for better handling, having the correct part numbers is essential. This guide covers OEM and aftermarket suspension part numbers for the DC5 Type R, helping you find exactly what you need.
Understanding DC5 Type R Suspension Part Numbers
The DC5 Type R suspension system includes struts, springs, control arms, bushings, sway bars, and more. Each component has a unique part number assigned by Honda or aftermarket manufacturers. Using the correct number ensures compatibility and performance. OEM part numbers typically start with a prefix like 516xx for struts or 526xx for springs, while aftermarket brands use their own numbering systems.
Why Part Numbers Matter
A wrong part can lead to poor fitment, altered geometry, or safety issues. The DC5 Type R has specific spring rates, damper tuning, and ride height different from the standard RSX or non-Type R Integra. Always verify with your vehicle's VIN or chassis number when ordering.
Where to Find Original Part Numbers
Original part numbers are stamped on the components themselves. Common locations include the strut body, spring coil, or control arm casting. You can also find them in parts catalogs from Honda or online databases. Dealership parts departments can look up numbers using the VIN.

Aftermarket Suspension Part Numbers for DC5 Type R
Many enthusiasts upgrade to aftermarket parts for better performance or adjustability. Below are common aftermarket options and their typical part numbers or model references.
Coilover Kits
When replacing the entire strut and spring assembly, coilovers offer adjustable ride height and damping. Popular brands and their part numbers:
- Tein Flex Z: Part number GSG20-11132 (for DC5 Integra Type R / RSX Type S)
- BC Racing BR Type: Part number BC-DC5-BR (typical kit)
- KW Variant 3: Part number 10220047 (for DC5)
- Ohlins DFV: Part number HOA DC5-01
Coilover kits come complete with springs, dampers, and top mounts. Verify fitment for right-hand drive (JDM) or left-hand drive (USDM) versions, as brake line brackets may differ.
Lowering Springs
If you want to keep the OEM struts, lowering springs lower the car and improve stiffness. Common part numbers:
- Eibach Pro-Kit: Part number 30100.140 (Lowers ~1.2 inches)
- H&R Sport Springs: Part number 28746-1 (Lowers ~1.3 inches)
- Tein S-Tech: Part number SKH01-11132
Sway Bars
Thicker sway bars reduce body roll. Upgrade part numbers:
- Eibach Anti-Roll Kit: Part number 36060.140 (Front 21mm, Rear 18mm)
- Progress Technology: Part number 65.1500 (Front 22mm, Rear 19mm)
- Whiteline: Front sway bar part number BHF44Z (22mm), Rear BHR44Z (18mm)
Bushings
For tighter handling, polyurethane bushings are common. Energy Suspension and Whiteline offer master kits. For example:
- Energy Suspension Master Bushing Kit: Part number 16.3101 (for DC5)
- Whiteline Control Arm Bushing: Part number W0502 (front lower control arm)
How to Find the Right Suspension Part Number for Your DC5
To ensure you get the correct parts, follow these steps:
- Identify your chassis: DC5 Type R (Japanese) vs. Acura RSX Type S (USDM). Some parts have subtle differences.
- Check your VIN: The VIN gives the exact model year and production details.
- Inspect the existing parts: Look for original part numbers stamped on the metal or printed on stickers.
- Use online parts catalogs: Websites like HondaPartsNow or OEM parts sites let you search by VIN or model.
- Contact a specialist: Performance shops or Honda dealer parts departments can confirm compatibility.
Common Mistakes to Avoid
- Mixing up left and right components (strut assemblies are side-specific).
- Assuming RSX Type S parts are identical to DC5 Type R – they are largely interchangeable but brake line routing and top mount can differ.
- Using aftermarket springs with worn OEM struts – replace both at the same time for best performance.
Common Suspension Upgrades and Their Part Numbers
If you are planning a suspension refresh or upgrade, here are typical combos with part numbers:
Full OEM Replacement
Replace all worn struts, springs, and mounts with OEM parts. Use the part numbers listed in the OEM section. This restores factory ride quality.
Budget Performance Upgrade
Install Eibach Pro-Kit springs (30100.140) and Koni Yellow struts. Koni part numbers for DC5: Front 8745-1348L/R, Rear 8040-1378L/R. These provide adjustable damping and a moderate drop.
Track-Focused Setup
For autocross or track days, consider Ohlins DFV coilovers (HOA DC5-01) plus Whiteline sway bars (BHF44Z/BHR44Z) and polyurethane bushings. This combination offers maximum adjustability and stiffness.
Final Recommendations
When selecting suspension parts for your DC5 Type R, start by determining your goal: restoration, daily driving improvement, or track performance. Always cross-reference part numbers with your specific vehicle to avoid fitment issues. For reliability, reputable brands like Tein, Eibach, BC Racing, and Koni have proven track records. If you need exact OEM fit, stick with genuine Honda parts. Aftermarket parts may require additional components like camber adjustment kits (e.g., SPC 67560) to correct alignment after lowering.
Keep in mind that suspension labor can be significant, so invest in quality parts that match your driving needs. Whether you are rebuilding with OEM or upgrading with aftermarket, using the correct part numbers ensures your DC5 Type R handles the way it should.
