Any roll cage that fits under the hardtop of a Blazer/Bronco/4Runner/Ramcharger will fit under the Softopper with no issues However, the Softopper may not retract with the rear roll cage installed without needing to go through an extra step. You just take the folding frame off the pivot pins and lower it into the bed, then fold it backward, and then pop the folding frame back onto the pivot pins.

We warrant all of our Softoppers to be free from defects in material and workmanship for a period of one year, with the exception of vinyl windows and zippers, provided there has been normal use and proper maintenance.

Vinyl Windows are warranted for a period of 3 months from the date of purchase.

Zippers are guaranteed to be in perfect working condition when leaving the factory. Due to atmospheric conditions, dirt, sand, road grime, dust, and abrasive cleaners, etc., zippers are warranted for a period of 6 months from the date of purchase.

Toyota 4 Runner, Blazer, Jimmy, Scout, Bronco, and RamCharger side curtain windows are warranted for 45 days from the date of purchase. Retracting or closing the top when the temperature is below 40 degrees may void the warranty on the side windows, as clear vinyl plastic can crack very easily at these temperatures. Use caution when retracting the top or cleaning off the windows in freezing temperatures.

Additional Information

Installation/Removal
The Softopper installs in minutes with custom clamps without any permanent modifications required. No drilling needed. Non-adhesive weather stripping provides waterproofing for your entire truck bed. It takes one person mere seconds to remove your Softopper entirely and folds flat for quick, easy storage in any space.  

Modular and Versatile
Customize your Softopper for how you work and play. In addition to the fully open and fully closed configurations, the canopy’s side panels and rear window roll up for easy access. No more crawling through the bed to get to gear up front. It’s also dog friendly. Open up the sides and give your pal plenty of air with protection from the sun and rain. Replaceable clear vinyl windows provide complete visibility through your truck bed.

Quality/Durability
Made in North America from the highest quality materials. A rust-free, anodized aluminum frame supports a 2-Ply, laminated PVC-coated canopy. The canopy is waterproof, UV, rot and mildew resistant, and is incredibly easy to clean. This 4-season sailcloth shrugs off beating sun, pouring rain, heavy snow and hurricane-force winds. Uses heavy duty #10 YKK zippers. The non-adhesive weather stripping protects your entire truck bed. And all parts are user replaceable.

Substance with Style
Available in three colors: Stealth Black, Desert Tan, and Battleship Gray. There are three options for the replaceable window panels: Clear, tinted and solid. Looks as great as the day you bought it, for years to come.

Everyday Utility
Strikes the balance of bulky, heavy camper shells and space-limiting flat tonneau covers. Use fully closed for weather protection and security, quickly collapse it open for hauling or go safari style with sides rolled up. No significant change in gas mileage. No wind noise even when driving at highway speeds.
