The original Vard instruction sheets reveals that you could get special order booster springs for your frontend if you were planning on running a front fender and the usual extra garbage like spot lights, windshield, mirrors and stuff like that... Only problem is – the Vard special order booster springs aren’t exactly something you can just get at the local McDonalds, and since I’m running all the extra cheese on the ’47 I was getting a bit anxious since I really hate to shop at other places than McDonalds, and also because I really hate spongy frontends.
That was until I found out that Knucklehead valve springs has got the exact same inner and outer diameter as the Vard booster springs must’ve had!! They also have the perfect squeeze fit inside the bottom retainer washer.
And the Knuckle valve springs even has the perfect 'height' inside the bottom aluminium tube part of the fork, all this almost makes you wonder if someone at Vard had a set of Knuckle valve springs laying around...
I'm also pretty sure the Knucklehead valve springs has pretty much the exact same spring rate and wire diameter as the Vard booster springs since they bottom out at just the right height!
