Equipment Lease Options

Dynojet offers competitive and affordable lease-purchase options through programs that are provided by third party Equipment Leasing Partners. Over the years we have developed strong relationships with our vendors and trust in their abilities to provide prompt service, and ‘best in the business’ lease rates for our dyno customers. We have long term partnerships with lease vendors who can facilitate lease/finance programs for all types of buyers – whether you’re a new start-up performance shop or a multi-line dealership.

Our Leasing companies are quick to respond to your needs, and after receiving your basic one-page application, you can expect an offer put together for your lease within 24 hours, many times the same day! Most of our Leases are structured with a $1 buy-out (some states are restricted to a slightly different term) and this makes Leasing your dyno even more attractive.

Equipment Leasing offers several key advantages to a conventional bank loan or standard financing. Here are a few of the key advantages:

  • Tax advantages including easy to implement deductions, and leasing may help you to avoid the Alternative Minimum Tax. A larger deduction, would be more cash in your pocket! Thus reducing the true cost of leasing.
  • No down payment or low down payment. Leases can be structured with very little down, or nothing down, upon approved credit.
  • Some leases can be structured to fit your cash flow needs, such as Seasonal Payment packages, whereby your payments will be higher during your peak earning months (summer) and then lower in the Off-Season (winter).
  • Secure 100% financing, Plus ‘soft costs’ such as computers, installation, shipping, taxes, etc. Usually up to a 10% addition to the primary dyno cost.
  • Conserves capital and credit. This frees up your funds for any immediate needs that may arise such as payroll, or quick capital purchases that may arise.
  • Leasing can offer longer terms than a conventional loan, thus lowering your monthly payment. We currently offer as long as 72 months, in some cases.
  • Hedge against inflation. Your payment will remain the same, for the term of the lease, even if the buying power of the dollar fluctuates.
  • Quick and efficient, as there is very little paperwork for most deals under $50,000, and you will have an offer within 24 hours, most on the same day!

A final thought on leasing - We have done the shopping around for you and our Lease Partners offer the best rates in the leasing business, with a commitment to honesty and integrity.

Some of our customers have procured their own financing and leasing and we do welcome that, however we would caution you to investigate any company that may be offering you a deal that is simply ‘too good to be true’. We recommend a simple Better Business Bureau search, before you sign any documents or send any payments into a funding source that might be questionable.
