While testing larger tires for our mud runs, the stock springs didn’t give enough clearance. The 31s are fine, but 33s need a bit more. But since time and money aren’t plentiful I simply buzzed on some new Daystar bumpstops to limit suspension travel and save the tires. The old red poly units came off easily enough, after being beaten into submission for 25 years. Information: Daystar, www.daystarweb.com.
