    Weaver w-RJ35 Sliding Jack

    Posted by Greg Rice on 17th Feb 2024

    This hydraulic Jack is a game changer for the 4 post lift I purchased from Derek Weaver a couple of months earlier. High quality and easy to use! Derek Weaver is the best car lift supplier to my experience by far. Super fast shipping and superior customer service. I highly recommend Derek Weaver.

    Arrived with out instructions, so used it anyway. Later, when I downloaded the instructions saw that the pump reservoir was shipped dry and to add fluid before use. Worked anyway. Also it's got two safety locks, and if you don't know that, your car won't come off the jack (jack doesn't go down all the way. Again, it would have been nice to have the instructions when I received it. Great Jack though.

    Smooth and powerful

    Posted by Steve on 15th Aug 2018

    These are a must. Raised my car off the lift to change u joints and was able to do the whole job without having to lay on the floor 1 time. Smooth & powerful operation.

    A must have!

    Posted by Vintage RPM on 22nd May 2018

    This is my third lift and jack... jack is a must if you work on your vehicles suspension, brakes or tire rotation. Some people opt for a roller type center jack, but for my work, the rolling jack is a detriment as the vehicle will move/ slide on jack. I truly wouldn’t know how to work without it!

    If it only had rollers

    Posted by Greg B on 19th Feb 2018

    This would be a 5 star if it had rollers to make it easier to move from end to end of the lift great jack for the price.

    Our 3rd Direct lift

    Posted by Pratt Customs on 22nd May 2017

    This is the best addition to our lift. Makes working on the suspension so much easier. This is our second lift we have with the pro jack.

    Roling jack for 4 post lift.

    Posted by Curt Wright on 12th Oct 2016

    Great value and GREAT product. I recommend the 4 post lift and the rolling jack to everyone, especially the more "senior" group like me who still love to work on their cars. The delivery was quick and packaged very well. The people were very knowledgeable and made the complete experience great.

    Pro Jack- a must have

    Posted by Mickm on 3rd Nov 2015

    When ordering my new Pro Park lift it was a no brainer to order the Pro-Jack at the same time. I had one with my last lift and sold it to the buyer of my home with a promise to have another one when I got ready to order. The jack works great, and is universal in how many ways it can help you work on the front and rear of your vehicle. I highly recommend this product.

    Great Sliding Jacks

    Posted by Steve Harris on 13th Aug 2015

    Bought 2 jacks to go with my Pro Park 9 lift. They work great. Easy to install and move about. Anyone with a 4 post lift should add these jacks. You would not be sorry.

    Must have accessory for any 4 post lift.

    Posted by Steve Hayes on 8th Jul 2015

    If you own a 4 post lift, you need this jack! The jack weighs in at a hair over 300lbs and is easily capable of lifting 3500lbs. Well built and a very good value. This jack will withstand the rigors of a commercial shop without a problem. It is easily the best 4 post lift accessory I have.

    The perfect addition to a 4 post

    Posted by Don on 3rd Jun 2015

    Should be standard equipment with every 4 post lift. Safe and secure way to elevate either end of a vehicle. Well made and easily operated

    Pro Jack

    Posted by Dan Stewart on 19th Feb 2014

    The Pro Jack lift was purchased to compliment the 4-post lift I purchased from Derek Weaver. This is a heavy-duty and quality piece of equipment that required minimal time and effort for installation. At 350 pounds, I'm confident the Pro Jack will fulfill my "lift on a lift" needs for many years to come. A great jack sold by very courteous and knowledgeable staff.

    If you are going to use your lift for anything other than parking an extra vehicle I do not know how you would do it without this jack.

    3500 JACK

    Posted by clovisvette on 12th Nov 2012

    Easy transaction. Excellent communication. Fast shipping

Derek Weaver Company is proud to offer our high quality products with free shipping or warehouse pickup. Here's how it works...


All Products on our website are offered with "Free Shipping". This means the freight charges are included in the price. Most of our products weighing less than 800-lbs. are offered with “Absolute Free Shipping” which means there are no extra fees. In this case you will notice the phrase “FREE SHIPPING! Includes Free Residential and Free Lift Gate Service!”, in the description of the products page. Absolute Free Shipping also means there are no additional fees for Liftgate Service or Residential Delivery. The only additional fee that you may incur would be if the address were changed during shipment which would incur a reconsignment fee by the freight carrier that we would only pass on if it were not our mistake.

For equipment over 800-lbs (most 2 & 4-Post lifts) there are some limitations for Free Shipping depending on weight and delivery location. In this case you will notice the phrase “Free Shipping To Over 85% of the USA - See Where It's Free” in the description of the products page. Most of the USA will require no additional fee. This applies to over 85% of the continental USA (lower 48 states). Free shipping does not apply to Alaska or Hawaii. Some parts of the country are affected by higher freight rates due to the combination of weight and delivery location which will require a small additional charge to cover the higher rate charged by the freight carriers. Our shopping cart will not calculate the difference (added fee), so we will contact you if this is the case. Rather than advertise the higher rates across the board we choose to show the lowest possible cost to most of the country. Like “Absolute Free Shipping” there will be no extra charge for lift gate or residential delivery. The following areas may have additional freight: North Western US, North Eastern US, Long Island, Western Colorado, the Dakotas, some parts of Florida & California and any area deemed a remote location by the freight company. Prior to ordering give us a call at 817-560-9510 or email and we can provide accurate information regarding Free Shipping or any additional charges.


Shipping and delivery time given during the freight quote process is an estimated time of delivery given by the carrier. Choosing Liftgate Delivery may extend delivery times due to limited liftgate equipment at the delivering terminal. Meeting the delivery schedule is subject to the day the freight is shipped and the carrier’s ability to meet their schedule. Derek Weaver Co., Inc. does not guarantee that a carrier can meet their projected delivery time but we will provide you with the proper tracking information by email so you can follow the tracking time and arrange for special delivery needs with the carrier as needed. Any additional fees incurred as a result of consignee being unable to meet scheduled delivery time or cause for redelivery or reconsignment to a different location will be at consignee’s expense.


Choosing Residential may extend the estimated delivery time due limited liftgate trucks at the delivering terminal, additional communication and handling by the freight company. Please keep this in mind when choosing residential delivery.


Make sure you can unload the freight. A forklift or lifting equipment is required for items over 800-lbs. The trucking company is only responsible for delivery to your loading dock if delivered to a business address or curbside if a residential lift gate delivery. Lift gate service is available for some equipment and can assist in unloading 2 and 4-post lifts however you will still need a forklift. Liftgate capacity is typically 1000-lbs and cannot unload a 2 or 4-post lift on its own.


If you are unable to unload a truck, we have the option of letting you pick the freight up at the closest terminal to your location. When picking up at a terminal, the freight company will load your truck or trailer for you which is included in the freight cost. Call our office (1-817-560-9510) to determine the location of the closest terminal. If you require terminal pickup please place a note in the comment box requesting terminal pickup and we will contact you with the terminal location. Covered trailers or trailers with ramps are not acceptable as they prevent the forklift from getting the load into the trailer. They will not drive onto a ramped trailer. Please remove the ramps prior to picking up if possible.

All shipments must be inspected immediately upon receipt



Choose this option if you have minor dings and scratches or a part that needs replaced to make the unit satisfactory. Make note of the damage before you sign the freight bill. You will be responsible for filing the freight damage claim with the carrier. Derek Weaver Co, Inc. will provide any replacement parts or touch up paint needed should you choose this option and the carrier should provide for reimbursement. If you have any questions or need further assistance, please call our customer service department @ 1-817-560-9510


Choose this option if the carrier has severely damaged the freight beyond your judgment of a simple repair. Derek Weaver Co, Inc. will file all freight claims. Get a copy of the freight bill from the truck driver and email it with a brief explanation of the situation to us. A replacement will be shipped as soon as we verify possession of the freight with the carrier.


If you would like to pick-up the item at one or our warehouses, please call ahead to make sure the item is in stock and schedule your pick-up. Picking up at our warehouse will save you in freight fees but will require sales tax to be collected. If you do not see a pickup price on our website for the product you are interested in you may call our office for more information.

In Texas we load Monday – Friday by appointment only.

In North Carolina we load Monday – Friday by appointment only.

All Two Post and Four Post Lifts require trailer for pickup. Be prepared for pick-up by understanding the item’s weight and dimensions and using the proper truck and/or trailer for hauling. We cannot load open or enclosed trailers with ramp gates. Our warehouse will load the item onto your vehicle and/or trailer but is not responsible for properly securing the load on your vehicle and you will need to make sure you have the proper straps and equipment for hauling. All items for local pick-up are charged state sales tax at the appropriate local rate. If you have any questions or need further assistance, please call our customer service department @ 1-817-560-9510
