Rock Slide Engineering 2nd Gen Gas Spring Replacement - 4 Door - SL-200-SP4

The Rock Slide Engineering 2nd Gen Gas Spring Replacement – 4 Door (SL-200-SP4) is the purpose-built extension spring update designed to replace the original gas spring on your Generation 2 Step Sliders. If your Gen2 Step Sliders have lost their smooth, controlled deployment or the gas spring is no longer performing the way it did when new, this is the direct replacement part you need to restore full functionality — no guesswork, no universal-fit compromises.

Key Features & Benefits

• Designed Specifically for Gen2 Step Sliders: This is not a generic spring — it is engineered as a direct update for Rock Slide Engineering's second-generation step slider system, ensuring proper fit and function without modification.
• Extension Spring Design Update: Rock Slide Engineering developed this extension spring to replace the original gas spring mechanism on Gen2 sliders, addressing long-term wear and improving durability of the deployment system.
• Restores Slider Functionality: A failed or weakening gas spring can leave your step sliders sluggish or non-functional. This replacement gets your sliders operating correctly again, keeping your entry and exit assist working as intended on the trail or in daily use.
• Installation Without Removing Sliders: Based on real-world owner experience shared in Jeep enthusiast forums, this spring update can be installed without having to fully remove the step sliders from the vehicle — a significant time saver during the repair process.
• Regularly Stocked Product: Unlike some specialty parts that require long lead times, this item is a regularly stocked product, meaning faster fulfillment and less downtime for your build.

Fitment

This gas spring replacement is compatible with Rock Slide Engineering Generation 2 Step Sliders installed on the following 4-door Jeep platforms:

• Jeep Wrangler JK – 4-Door
• Jeep Wrangler JL – 4-Door

Important: This is the 4-door version (SL-200-SP4). If you have a 2-door Jeep Wrangler TJ or LJ with Gen2 Step Sliders, you will need the separate 2-door gas spring replacement part instead. This part also requires that you already have Rock Slide Engineering Gen2 (second-generation) Step Sliders installed — it is not compatible with first-generation or third-generation Rock Slide step slider systems. If you are unsure which generation of step sliders you have, contact our fitment team before ordering.

Frequently Asked Questions

Q: Will this gas spring replacement work on my 2-door Jeep Wrangler TJ or LJ?
A: No. The SL-200-SP4 is specifically the 4-door version, compatible with the Jeep Wrangler JK 4-Door and JL 4-Door. Rock Slide Engineering makes a separate 2-door version for the Wrangler TJ and LJ. Make sure you order the correct part for your vehicle's door configuration.

Q: Do I need to remove my step sliders from the Jeep to install this spring replacement?
A: Based on owner-reported installation experiences in Jeep enthusiast communities, this spring update can be installed without removing the step sliders from the vehicle. This makes the job more straightforward and reduces total labor time significantly.

Q: Is this compatible with Gen1 or Gen3 Rock Slide Step Sliders?
A: No — this replacement is designed specifically for Rock Slide Engineering Generation 2 (Gen2) Step Sliders only. If you have a different generation of Rock Slide sliders, this part will not be the correct replacement. If you're unsure which generation you have, contact our team for help identifying your sliders before placing your order.
