SecureCaps Prevents Unnecessary Repairs

Our precision-machined locking dipsticks fit just like the o.em. products but provide a better grip and easily pop into place without the use of your existing o.e.m. parts. 

The stock spring-loaded oil caps on Harleys are not strong enough to protect your engine. These cheap parts are known for wobbling loose and popping up or off while you are riding down the road.

SecureCaps clinch the cap in place, preventing messy spray outs and unnecessary engine repairs. Fitted with silicone and fluorocarbon O-rings, SecureCaps are built to withstand the heavy heat Harley engines produce even if you have made powerful torque and horsepower upgrades.

You can easily remove a SecureCap even when the engine is hot without getting burned, making this a necessary item for long road trips, everyday riding or racing.

Protect Your Harley Engine

Dynamically Cool Dipsticks

SecureCaps are more than just an aftermarket anti-theft device. Unlike the original part, our dipsticks connect directly to the cap, so you no longer have to blindly swirl your fingers in oil until you find the lost line.

Available in day glow green for DYNA models, hot rod yellow for FLH bikes or cherry red for SOFTAIL Harleys, these vibrant colors create a great contrast against the amber-hued oil.

You will be able to determine the exact oil level whether you are standing in the dazzling sunlight or under a starry sky.
